What is a csp plate. DSP board: technical characteristics, description, prices, reviews. Technical characteristics of cement bonded particle board
When constructing any structure, and even more so if it is residential, each of us is interested in not only its safety, but also its environmental friendliness. And therefore, in the construction of houses, they are increasingly beginning to use cement-bonded particleboard.
Thanks to their natural and high-quality ingredients, they have no harmful effects on human health or the environment.
These slabs are used not only in prefabricated structures, but also for internal and external construction work, namely for the manufacture of ceilings, window sills, flat roof, various storage facilities, communication boxes, mobile boiler rooms and residential containers and much more, which are subject to the most stringent requirements for moisture resistance, soundproofing and fire safety.
DSP board is a universal building material in the form of monolithic sheets with a smooth and hard surface, produced in accordance with the requirements of GOST 26816-86.
Cement particle boards are made from cement, coniferous tree shavings, minerals and water. Due to the presence of silicate cement, there is no need to use synthetic glue, and therefore there are no such harmful substances such as phenol, formaldehyde, etc.
Additional information on use is available in the collection of articles. The most low price DSP from leading manufacturers.
ANY CUTTING OF CEMENT PARTICLE BOARDS TO CUSTOMER SIZE.
When choosing cement bonded particle boards, you need to consider where they will be installed. Standard dimensions of DSP: length 3200 or 3600 mm, width - 1250 or 1200 mm.
When choosing the thickness of the sheet, it is necessary to take into account that as the thickness of the sheet increases, an additional load on the structure occurs and at the same time under high loads and the effects of cement- particle board may break. Based on all this, the recommended thicknesses are:
20 mm - 36 mm - for installing canopies, window sills, etc.
10 mm -20 mm for permanent formwork
8 mm for subfloors
From 12 to 36 mm for frame construction
10, 12 mm for partitions
12, 16 mm for external cladding

Application of CBPB
What's new in the field of modern CBPB production?
New technology production of cement bonded particle boards allows you to obtain products with extremely low thickness variation. This development of events became so successful that in this regard, there has been a steady demand for the sale of CBPB boards with a thickness 4 mm. This is the minimum tthickness for them, which can be produced. The first batch of 6 mm slabs is produced in Magdeburg and was so high quality that all the plates were within thickness tolerance± 0.2 mm. Such fine tolerances make the costly grinding process unnecessary. In addition, the plates have
smooth surfaces consisting from very small particles, and particle sizes gradually increase towards the center boards Not new, but not so widespread yet famous csp board with embossing and surface coating in various configurations, , such as
brickwork wooden boards or a natural stone. Especially in Japan a large number of those who want to buy csp these boards made the sale of csp Very successful business. More than 90 % of Japanese buy such slabs from external walls.
Based on success in Japan, several companies in many other countries have started test market for the sale of chipboard. In its simplest form, paint is applied to the surface usually with a roller or spray in the desired colors for which currently availablevarious suitable paints and coatings. In a higher quality version, the coating is performed from reinforced hard plastic with relief the surface that results so tough and durable that it can match the strength become.
Where to buy DSP sheets?
Not entirely new, but very interesting, is the use of cement particle boards as tiles. In Hungary, the use of painted and unpainted tiles on walls and roofs is common, but of particular interest are roofs and walls made from tiles developed in some states in the western United States. It undoubtedly looks beautiful, but is flammable. Nevertheless, the sale of CP is in full swing.
Very interesting is the successful use of large sizes of prefabricated walls and floor elements assembled from DSP panels. All elements consist of panels arranged in composition with metal or high-strength plastic spacers and have the necessary internal reinforcements. Each element is precisely cut to precise dimensions in the factory, including openings for cables, pipes, ducts, doors and windows. On site, prefabricated elements only need to be installed and filled with concrete. Before the concrete is poured, water, gas and electricity piping will first take place in the wall cavities. After the construction of the building, the external walls are insulated with 7 cm thick sheets of expanded polystyrene, which are covered with a thin layer of plaster or elastic finishing. Only three workers are needed to install all the walls and floors for single-story buildings per week. Thanks to the prefabricated structure system, it is fast, high quality and at an affordable price per sheet. Such effective method construction of the building does not create a lot of dust, waste and normal noise on construction site, and provides a quick return on investment. DSP with a thickness of 10, 12 and 16 mm are used as external and internal lining walls (on a frame-sheathing), cladding of columns or crossbars of public, industrial and agricultural buildings.
Moisture-resistant partitions - DSPs with a thickness of 12 and 16 mm are used in rooms with high humidity. This is due to the corresponding physical and mechanical properties of the material. DSP can be used in partitions of sanitary units of buildings for various purposes.
Interior wall decoration - DSP, having certain fire-retardant properties, is an environmentally friendly and moisture-resistant material, and therefore is successfully used for interior and exterior finishing premises of residential and public buildings with dry and normal operation.
Floors - DSP with a thickness of 16, 24 mm can act as the following floor elements: base under various coatings, underlying layer, leveling layer, finished floor with front covering. DSP with a thickness of 24 mm can be used for the construction of prefabricated floors on bulk foundations in warehouses and utility rooms. This eliminates wet processes, which allows work to be carried out at negative temperatures. In addition, slabs can replace cement screed. The advantages of this solution are: reduction in labor intensity; opportunity to lead renovation work without stopping production. The 8 mm thickness is also a popular position and is constantly available in our warehouse.
Removable, permanent formwork - slabs with a thickness of 12, 16 and 24 mm can be used as removable or permanent formwork for building foundations. The simplicity of the formwork design will reduce labor costs and achieve a significant reduction in cost when performing zero-cycle work.
Window sill board - 24mm thick CSP window sills are ideal for any modern interior. According to its characteristics, a window sill made of CSP is stronger and more durable than its wooden counterpart.
Among the slab and sheet materials used for finishing and constructing partitions and various design elements, one cannot ignore cement-bonded particle board or cement-bonded particleboard. Of course, in terms of popularity it is inferior to drywall, but, as practice shows, it is also suitable modern world there is a place. Most often, the DSP board is used by builders as formwork. It is smooth, with good strength, plus - with its help, it is much faster to assemble formwork than from boards.
Many may doubt that the use of DSP is advisable for the construction of formwork. After all, it can be replaced, for example, by metal or plywood, which are also used. This is probably true, but a slab with a thickness of 24-26 mm can withstand quite serious loads. In addition, if you install permanent formwork using cement-bonded bonding material, then, in fact, you will get a finished foundation or other structural element of the building. And this is a big plus in many situations.
In addition, it is necessary to take into account the conditions under which the room being finished will be used. For example, if this is a gym, then there can be no talk of any drywall. He just can't withstand the ball's impact. And the DSP boards will hold up. They can be used for strapping and sheathing frame houses. Today you cannot find better material for this value. Another advantage is the ability not only to paint the cement-bonded particle material, but also to use it as a finishing material. Fortunately, manufacturers today offer a huge assortment with design to suit different materials, as shown in the photo above.
DSP production technology
From the name itself it becomes clear that the main components of this material are cement (65%) and wood shavings (24%). All this is mixed with water (8.5%), and added to the resulting mixture various additives, improving the technical characteristics of the slab (2.5%).
In the process of producing CBPB, two types of particle boards are used. They differ in size: small and medium. The slab itself has a three-layer structure, so medium-sized chips are poured into the second layer, and small chips into the first and third. The production process itself takes place in the following sequence.
- The shavings are mixed with hydration additives.
- Cement grade M500 is added to the resulting mixture.
- Water is pouring in.
- The solution is thoroughly mixed until a homogeneous mass is obtained.
- The first layer with small shavings is poured into the mold.
- The second layer with medium-sized shavings.
- And the third layer.
- Pressing is in progress.
- After which the semi-finished material is heated to +90C for eight hours.
- Then it is dried under natural conditions for 13-15 days.
- After which, depending on the batch, it is either polished or simply stored.
Specifications
The fact that this is a durable material is clear because it contains a cement component. But it is also moisture resistant due to the use of hydration components. Plus, DSP boards have excellent bearing capacity, which cannot be said about gypsum board or plywood. But a lot will depend on the parameters of the stove.
As for the width, it is standard - 1.2 m. But the thickness and length are dimensions that vary over a fairly wide range. As for the length, the manufacturer can cut it to any size if the order batch is large. But there are also standard values: 2.7; 3.0; 3.2 and 3.6 m.
As for thickness, there is a fairly decent range here too: from 8 to 40 mm. Accordingly, the weight of the product will increase with increasing thickness. For example, a slab 2.7 m long and 8 mm thick weighs 35 kg. With a thickness of 40 mm, the weight will increase to 176 kg.
With a DSP length of 3.2 m and a thickness of 8 mm, its weight will be 41 kg. With the same length and thickness of 24 mm, the weight will be 124 kg.
There are no rounded edges or chamfers in the design of the DSP boards. The edges are straight and cleanly cut, so there shouldn't be any problems with joining panels and fitting. They do not need to be treated with antiseptic compounds before finishing, because during the manufacturing process an antiseptic is added to the raw solution.
Other technical characteristics according to GOST:
- Withstands high sub-zero temperatures. In this case, the defrosting process can occur up to 50 times. After which the strength of the slabs decreases by only 10%.
- The error on the outer plane is 0.8 mm.
- The difference in the lengths of the diagonals can be 0.2%. This is practically no more than 5 mm for a length of 2.7 m.
- Thickness error (permissible) is no more than 0.8 mm. This is for unsanded material, for sanded material 0.3 mm.
- Water absorption is 16%, while per day at high humidity the slab should not increase in size by more than 2%.
- Withstand tensile loads - 0.4 MPa, bending loads 9-12 MPa, depending on the thickness of the product. The thicker it is, the less it can withstand bending loads.
Manufacturers today offer two types of cement-bonded particle board material, which differ from each other quality characteristics. These are TsSP-1 and TsSP-2. The first one is better.
There is an opinion that slabs of this type are inferior to plasterboard in many respects. You should not compare these two materials; they have different purposes and different areas of application. The examples described above confirm this. Of course, DSP has its drawbacks, which we’ll talk about.
- Compared to plasterboard, cement-bonded particle boards cost almost twice as much. But gypsum board cannot be used for exterior decoration, and it’s better not to sheathe a frame house with it.
- The weight of each slab can be terrifying, especially those with a thickness of more than 16 mm. You won't be able to work with them alone. Under them you will have to build a strong and reliable frame. And the foundation will have to be strengthened if they are used to cover a frame structure.
- In addition, the cement component gives the material increased strength, so it is difficult to process. Therefore, trimming should be done with a grinder or a hand-held circular saw, and not with a simple cutting tool, but with a diamond one.
- The frame has already been mentioned, but it must be added that profiles for drywall are not suitable here, especially if we are talking about exterior decoration DSP slabs. A standard steel profile is required here.
- When cutting slabs, a large amount of dust is released, so this operation should only be performed outdoors.
Wood processing technologies in Lately are gaining momentum. That is why today boards based on shavings, sawdust, and laminated materials, which are used in furniture production, are used everywhere.
Description and features
CSP - cement particle board, which has a sufficient level of strength. This allows them to be used in the construction of frame houses, where they are used on floors and walls. If somewhere such boards can be replaced with chipboard, OSB and others, then DSP will be especially relevant where humidity is high, for example, in a bathroom, toilet, furnace room. For the same reason, they can even be used for finishing facades, as well as as a roofing base before installation soft roof.
Cement particle boards
Speaking about the features, it is worth analyzing the structure of this material. The main thing that gives the slab its gray color is the cement. According to GOST, its mass fraction must be at least 65%. At the production stage, gypsum is added to it, as well as additives that increase plasticity.
The second component is considered to be shavings. Its mass fraction is at least 24 percent. The remainder includes water, as well as binding additives. Water, after reacting with cement and additives, evaporates, leaving space with air. This results in the slab becoming lighter and warmer.
Types on sale
Like any type building materials, DSPs have a number of varieties. Their subtleties relate to the production aspect, since these plates look different, are used in different industries, and have unique features.
The first option is fiberboard. The base used here is not wood shavings, but fibers, which makes the base viscous and especially tensile. To achieve additional strength, it is used at the production stage liquid glass and calcium chloride.
Thanks to their resistance to damage, the products are not only able to withstand heavy loads, but also resist the effects of sound. That is why fiberboard is often used as sound insulation in studios, shopping centers, bars, and discos. Despite these properties, fiberboard is easy to process yourself. To do this you do not need to have any special tool. It is easy to process even at home.
1. . This is the second version of the variety. Here sawdust is used as a wood binder. As production basis They use rice straw and reeds. Among all the raw materials used for production, wood chips provide the highest strength.
The performance characteristics here are lower than those of the above option, but the cost of such a product is also cheaper. As for the total weight, the sheets are heavier, but suitable for walls. That is why they are used to decorate low-rise frame houses of private construction.
Production of CBPB boards
2. Xylolite. This is the third variety. The strength of such products is so high that they can be used for both floors and walls. Lumber, namely wood chips, is used as the basis for production. On sale you can find not only the colors of the standard segment, but also various shades, which turns out to be quite profitable in terms of finishing. Sometimes they are even left without additional cladding, because against the background of the overall interior they look interesting and expensive.
Characteristics and dimensions
Characteristics of CBPB boards important at the selection stage:
- Weight of one cubic meter is about one and a half tons. It is important to take this into account when transporting when purchasing large volumes of slabs. Loading of packages is carried out using a manipulator. It can be used to organize delivery and unloading. As for the weight of one slab, it is small and installation can be done manually.
- Humidity up to 12%. This criterion corresponds to the state standard. Low humidity indicates that the stove does not absorb water even during operation. Therefore, it is supplied from the factory with a humidity of 9%, but even if it is used in rooms with high humidity levels, such as bathrooms, the material will not deteriorate at all even after a while. This implies another characteristic, such as water absorption in maximum quantities, which amounts to no more than 16% in one day.
- Sufficient thermal conductivity. Due to the high density of wood chips, the thermal conductivity is fixed at 0.26 watts per square meter. This is enough to use similar material in frame houses. Vapor permeability is 0.03.
- The material can withstand bending pressure up to 9 megapascals. As for the compression pressure, this value is 0.4 megapascal. Flammability is equal to class G1.
The technological feature of production allows us to produce slabs of different thicknesses on the market. Basically, they are fixed values from 0.5 centimeters to 4 cm, inclusive. The width may also vary. It is fixed at 120 and 125 cm, respectively.
Dimensions of CBPB boards
As for the length, this value is fixed at 270 and 320 cm, respectively. State standard production assumes deviations in the thickness, width and length of the material up to one and a half mm, inclusive.
Application area
Regarding the scope of application, it is necessary to highlight the sphere of private and capital construction. A private developer can use this material everywhere, from finishing floor surfaces to finishing walls. DSP slabs for flooring have found their application.
They are able to withstand heavy loads and are easily processed using special paints. They do not disturb the interior to some extent; on the contrary, they give it a finished look. The main thing is to perform the installation correctly, because if there is a violation technological process there is a possibility of losing the aesthetic appearance, as well as reducing the service life of the slab.
As for other areas of application, they are used for arranging the foundation. This is the so-called permanent formwork, with which the frame is made. The slabs are cheap, so it is convenient to use them here and leave them for later use.
They will be easy to finish on the outside, which in the future will not disrupt any of the aesthetics of the house’s appearance. Frame technology also involves application of CBPB boards as a basis for future walls and ceilings. I also use DSP boards for the partitions to construct the frame.
DSP is used in the construction of frame houses
Today they are used in homes frame type, and where they are used to hem ceilings, and they can also be used for roofing structures followed by finishing soft material. Such slabs are used to hem the back side of stairs, sew up communication niches, make blind areas and paths in the garden, and arrange subfloors.
The most important thing to know Dimensions of CBPB boards. For the ceiling, for example, the thinnest material is suitable, since it will fulfill its task of arranging the base even with the smallest thickness. Otherwise, the floor needs a thicker base, since its resistance to loads should be maximum. The same can be applied to formwork.
How to install correctly and what tools are needed?
Installation of DSP boards can be done by hand. It’s not difficult, the main thing is to follow the basic rules of work. As for the basic rules, we suggest considering installation using the example of arranging the facade of a private house. Here you need to follow the following steps:
1. The foundation needs to be established. These are a kind of bars measuring 50 by 50 mm, which must be fixed to load-bearing wall. If we have a frame house in front of us, then we can use the existing frame without additional modification.
Since the plate itself weighs a lot, it is not recommended to use a smaller cross-section, unless you can replace it with metal, 50 by 20 mm. The step between two adjacent beams should be no more than 60 cm. Vertical sheathing is performed with the specified step.
2. The insulation is being laid. For this reason, we previously chose a cross-sectional area of 50 by 50 mm. This is convenient for laying insulation with an overlap of 2 and 2 cm, respectively. The overlap is done in order to remove cold bridges at the junction of two plates.
Depending on the original base, the insulation is nailed either with special dowels or fixed to a wooden profile by further installing a wind protection membrane. The membrane is nailed to the tree using a stapler. One cm of space left between the insulation and the DSP board is a ventilation gap. It must be left during installation.
3. Installation of sheets. It is advisable to lay the first sheet perfectly level in order to limit the overall horizon for subsequent installation. The sheets are screwed using a regular wood or metal screw, depending on the base.
Before screwing the sheet, level it, fix it and make markings for further installation. Manufacturers recommend drilling holes for screws. To do this, use a drill of a smaller diameter. If you are not going to drill, then buy self-tapping screws with a drill.
Fasteners must be galvanized or pre-treated with special compounds. It is impossible for two adjacent slabs to fit perfectly against each other. It is important to leave a ventilation gap, which can be up to 0.5 centimeters inclusive.
4. Don’t worry if parts of such a slab break off somewhere. In the future, you can always cover the walls with another material, but even small chips will not harm the overall integrity of the surface. The easiest way to further finish is to paint the surface.
Frame house sheathed DSP
There are special paints for CBPB, which will give your home a sophisticated look. Paints are produced on the basis of acrylic or silicone, which makes them moisture resistant and allows them to maintain their saturation at critically low and high temperatures.
As for the tool, we need:
- A screwdriver, a drill with a drill whose diameter is smaller than the diameter of the screw.
- Level, wood saw, measuring tape, marking pencil.
Price
Price of CBPB slabs different. It is determined by the plant and the direct supplier. But, if we consider the middle segment of the market, then for an 8-meter particle board, it is quite possible to pay from 700 rubles. per sheet. We already talked about sizes earlier. So, the average sheet area is almost 3.83 square meters.
If we compare this price with OSB sheets, then for a similar square footage we can pay more than 1000 rubles. Therefore, particle board is more profitable than others finishing materials.
Otherwise, decide on the thickness and remember that the larger it is, the more expensive the cost of one sheet will be. For example, a similar sheet, but with a thickness of 12 mm, can be found on sale at a cost of 1,100 rubles.
Advantages and disadvantages
Advantages and disadvantages are important at the time of choice. They are worth considering, but you need to familiarize yourself with them first. Let's start with the advantages:
- Wide range of applications. This makes them multifunctional, since today sheets can be used for interior and exterior work. You have previously become acquainted with the scope of application and understand that they cover the entire spectrum of construction of private and capital houses.
- Covers a large area. By cutting just a couple of sheets, you can easily finish a fairly large area, about 8 square meters. The material is easy to process, so even if you do not have a specialized tool, you can always cut it into the necessary parts manually.
- The manufacturing process is quite complex, but no toxic harmful substances are used here. There is cement, wood, special glue, water and plasticizers. You can see for yourself that the material does not in any way spoil the surrounding atmosphere, does not violate the internal aesthetics of the premises and does not in any way affect people’s health from a negative point of view.
- Can be finished with modern materials. This can be not only wood and wallpaper, but also paint, which is important for a material with a similar structure. Its high noise insulation properties make it possible to maintain comfort in homes, as well as hide particularly noisy objects from strangers.
Today on sale there is not only gray DSP board, but also those that were originally finished as brick, ceramic tiles and other finishing options. All this allows you to inexpensively cladding your own house, bathhouse, garage and other buildings.
There are practically no disadvantages. Unless this includes big weight of CBPB board. This involves deepening the foundation, since the load on it will be large. During the installation process, it is necessary that the fasteners be galvanized or processed in a special way. Therefore, think about this moment in advance.
IN modern construction And finishing works The term DSP is often used. The abbreviation stands for cement bonded particle board, and it is one of the popular and high-quality building materials.
Thanks to innovative technology manufacturing, CBPB boards have unique characteristics that are noticeably higher than those of wood-fiber analogues, plasterboard and plywood. Let's consider key benefits this building material.
Main technical characteristics
Cement-bonded particle boards are made from crushed wood chips and cement, adding substances to the composition that completely eliminate the conflict of materials. The raw materials are laid one by one, forming a multi-layer sheet with special properties, which is formed by a hydraulic press.
As a result, DSPs have the following characteristics:
Sound insulation indicators - up to 45 dB.
Change standard sizes with prolonged exposure to a humid environment - no more than 0.3-2%.
Bending and tensile strength - 2,500-3,000 MPa, respectively.
Fire safety - class G1 (low-flammable materials).
The average service life is up to 50 years.
It is worth noting that DSP boards are resistant to temperature changes, are easy to process and are not susceptible to mold formation. Disadvantages include dependence on humidity environment: if the material is in contact with water for a long time, the service life is reduced to 15 years.
Is it burning or not?
The combustibility of a material is one of the key issues of interest to builders and finishers. Considering that the composition includes wood, cement particle boards can catch fire, however, this requires prolonged exposure to high temperatures.
When you are in a completely blazing house, the DSP needs contact the fire for at least an hour before it ignites. In addition, the material does not contain active chemical components, so even in the event of a fire, there is no risk of poisoning from combustion products.
Composition of the CBPB board
When producing cement-bonded particle boards, manufacturers are guided by GOST standards that are used for this type of building materials. In particular, the following ratio of components included in the finished product is used:
Portland cement - no less than 58%.
Additional impurities - 2.5%.
Crushed wood shavings - at least 30%.
It is necessary to clarify that the percentage of raw materials used must be indicated on the packaging. Here are the data recommended by GOST, which may differ slightly for the products of some manufacturers. However, when choosing a material, you need to focus on the given values: this is the key to the quality and strength of CBPB boards.
Application
The main area of use of this material is to increase the thermal insulation properties and sound insulation of premises. Therefore, the material is often used in private residential buildings and in the construction of commercial and industrial facilities.
Cement particle boards are optimally suited for interior and exterior wall finishing, floor preparation finishing. In addition, the material is often used for arranging interior partitions.
Regardless of the scope of application, DSPs are guaranteed to withstand the service life declared by the manufacturer, which is about 50 years!
Standard sizes
As already mentioned, DSP boards are manufactured in strict accordance with GOST standards, and accordingly have strictly defined external parameters. If we talk about standards, the following sizes apply:
Sheet length - 2,700/3,200/3,600 mm.
Width - 1,200-1,250 mm.
Thickness - 8-36 mm.
It is necessary to clarify that this data is relevant only for products from domestic manufacturers. The European construction market has different standards.
Sheet weight
In the table above, the data is shown in a separate column. The weight of the sheet directly depends on two fundamental factors: thickness and area of the product. At the same time, the length and width of the sheet are usually standard; only the thickness changes, which largely determines the performance characteristics and scope of application. Let's look at the change in the weight of a standard sheet (3,200 * 1,250 mm) depending on the thickness. It looks like this:
Thickness 10 mm - weight 54 kg.
12 mm - 64.8 kg.
16 mm - 80 kg.
20 mm - 108 kg.
The weight of the densest sheets can reach up to 194 kg However, such material is very inconvenient for independent work. For cladding walls and arranging interior partitions, sheets are usually used, thickness 16-20 mm.
How to cut this material
It’s worth clarifying right away that it is better to cut cement particle boards in production workshops: The work is very dusty and requires a special tool for an even cut. At home, you can use the following devices:
The working surface of the tool must be made of carbide materials, rotation speed circular saws: no more than 200 rpm.
To minimize room contamination and reduce the amount of dust, it is recommended to spray the surface of the material being cut with water and prepare a vacuum cleaner to suck up fine particles.

Useful to know during installation
It must be remembered that you need to work with cement particle boards very carefully: the large area of the sheet makes it fragile, so installation is carried out by at least two people.
In addition, CBPB boards are not laid closely; expansion joints must remain. The material contains wood, which tends to expand under the influence of a humid environment. Given this feature, it is not recommended to fill joints with putty. It is better to use a sealant that will not interfere with the expansion of the DSP boards.

Facades finished with DSP take on a stylish, modern look
DSP is a cement-bonded particle board. On English language sounds like “cement bonded particle board”. Refers to a variety of leafy composite material oriented for use in the construction industry.
Characteristics of CBPB boards: sheet dimensions and price, thickness, weight
Thanks to the variety of technical indicators that meet modern requirements, cement particle boards seriously compete with common flat slate and other sheet materials.
DSP board: technical characteristics, application
The main document that regulates the characteristics and use of CBPB boards is GOST 26816-2016. According to its provisions, two brands are distinguished - TsSP-1 and TsSP-2. They have some differences in the values of technical parameters.

The scope of application of cement bonded particle boards is quite extensive and includes several areas:
Weight of CBPB boards
Most often, the weight of building materials is estimated if a low-rise building is to be erected on its own. This indicator is directly proportional to the thickness and dimensions of the material.
If we consider a cement particle board with a length of 2700 mm and a width of 1250 mm, then the weight indicators depending on the thickness will have the following values.
With a length of 3200 mm and a width of 1250 mm, the weights will be as follows.
Note! Analyzing the indicators, it can be noted that with a thickness of 36 mm, the slabs become 4.5 times heavier than their eight-millimeter counterparts. Even 10 mm DSP has a fairly impressive weight, so it will be difficult for one person to work with such material.
Advantages and disadvantages of cement bonded particle boards
The popularity of DSP is based on a wide list of advantages of this material compared to analogues:
- Fire safety. Finishing made of cement-bonded particle boards does not support combustion. If a strong fire occurs nearby, they do not emit dangerous toxic elements.
- Multifunctionality. Possibility of using the material in different roles: partitions, finishing, creating a rough foundation.
- Biostability. Cement particle boards are not colonized by fungi. They are resistant to rodents and various bugs.
- Frost resistance. This characteristic becomes especially important when using the material in regions with severe winters.
- Reliability. Even under conditions of frequent temperature fluctuations, the slabs do not undergo deformation for a long time.
- Noise insulation. The structure of the slabs allows you to protect living spaces from external sound influences.
- Moisture resistance. Even when used for finishing external facades, the material withstands atmospheric conditions well.
- Quick installation. If a private house is being built, its finishing using DSP is carried out at a rapid pace, due to the large area of the sheets.
Among the disadvantages is the high weight of the material, which makes it difficult to use on upper floors without special equipment. Another inconvenient factor is the abundant formation of dust during the process of sawing slabs.
What and how are CBPB boards made from?
The composition of cement bonded particle boards includes the following components:
- Portland cement −65%;
- wood shavings −24%;
- water −8.5%;
- additional impurities - 2.5%.
As a supplement, aluminum sulfate and liquid glass are used. It is necessary to pay attention to the product passport, which reflects these indicators. Also included is a certificate of certification and a quality passport.
The technological process consists of several stages:
- The chip component is mixed with hydration additives.
- Water and cement fraction are added.
- A slab of the required dimensions is formed under pressure.
- It should be heated to 90 degrees and hardened under such conditions for eight hours.
The slabs are then aged to achieve their final hardness levels under natural conditions for two weeks. The last stage is grinding, if provided for in the technological map.
Slab manufacturers have special equipment, conveyor lines, comply with GOST standards, and carry out the necessary quality control.
Main sheet sizes, prices and where to buy cement bonded particleboard
GOST 26816-2016 regulates two standards for the length of CBPB: 3200 and 3600 mm. And also two width options: 1200 and 1250 mm. Among the assortment different manufacturers The most popular products are 2700 cm long with a standard width. Thickness values starting from 8 mm are graded in 2 mm increments. GOST reflects the possibility, if necessary, to order the manufacturer to produce slabs with other sizes.
The price of building materials also depends on the main dimensions. Below is an overview of the cost of the most popular types of cement bonded particle boards.
With a length of 2700 cm and a width of 1250 cm, prices vary within the following limits depending on the thickness.
| Thickness, mm | 8 | 10 | 12 | 16 | 20 | 22 | 24 | 36 |
|---|---|---|---|---|---|---|---|---|
| price, rub. | 677− 703 | 816− 875 | 917− 987 | 1154− 1192 | 1421− 1440 | 1500− 1548 | 1560− 1580 | 1 605− 1700 |
The price for dimensions 3200x1250 mm is the following average values.
| Thickness, mm | 8 | 10 | 12 | 16 | 20 | 22 | 24 | 36 |
|---|---|---|---|---|---|---|---|---|
| price, rub. | 714− 738 | 838− 898 | 946− 1019 | 1166− 1178 | 1419− 1576 | 1608− 1634 | 2173− 2185 | 2193− 2198 |
Price for dimensions 3600x1200 mm.
| Thickness, mm | 8 | 10 | 12 | 16 | 20 | 22 | 24 | 36 |
|---|---|---|---|---|---|---|---|---|
| price, rub. | 755− 950 | 970− 1200 | 1150− 1250 | 1360− 1550 | 1365− 1600 | 1850− 2005 | 2350− 2650 | 2700− 2885 |
Based on average prices, you can calculate how much it will cost modern material necessary for carrying out the planned work. For example, the price of a 16 mm DSP board with a length of 3600 mm is 1500 rubles. To cover the facade, 35 slabs will be required. Therefore, you will have to spend 52,500 rubles on the purchase.
You can purchase cement particle board in stores specializing in the sale of building and finishing materials. Here you can get necessary consultation to select the appropriate variety.
You can find many offers in online stores both from manufacturers and from representatives of companies producing this modern and popular material.
Handling rules - how to cut CBPB
Cement particle boards, which are superior in hardness, cause virtually no difficulties during processing. They drill and mill well. For example, screw drills are used to drill a hole and the work is done at high speed.
If it is necessary to cut CBPB, then at home they use different instruments. Be sure to wear safety glasses and a mask over your mouth and nose, as large amounts of dust are generated.
Expert's point of view
Dmitry Kholodok
Technical director of the repair and construction company "ILASSTROY"
Ask a Question"Can be used electric jigsaw, but you should select special files designed for cement. They are equipped with carbide tips.”
To reduce the amount of dust formation, it is recommended to irrigate the cutting area with water from time to time. You can remove dust immediately using a vacuum cleaner, which should be held by an assistant.For slabs thicker than 12 cm, it is advisable to use an electric disk tool.
Advice! Select discs that are designed for working on concrete, stone or brick. They are diamond coated. Preference is given to a circular saw, since when working with it, less dust is generated than from an angle grinder.
Scope of application of DSP in construction and repair
Considering the characteristics of DSP, its scope of application is quite extensive. When using, recommendations for selecting material thickness are taken into account.
DSP façade finishing
Facades finished with cement bonded particle boards become presentable appearance, the coating made of cement-bonded particleboard imitating brick looks especially attractive.
This building material does not require additional coating, reliably protecting the building from external influences. You can purchase cladding with the texture of stone, marble and other types of crumbs.
If the goal is insulation, then a material with a thickness of 8–16 mm is used, under which the insulation is first laid. Then the sheathing is formed and the facing slabs are fixed. A ventilation gap is provided.
Application of DSP boards for flooring
DSP is becoming a popular material when laying floors. If you plan to directly lay the DSP on the floor along the joists, the thickness of the material is selected in the range from 20 to 26 mm. This provides good strength with an average lag pitch of 0.6 meters.
The result is a smooth rough base, ready for finishing. Self-tapping screws are used as fasteners.
Often, 12mm DSPs are used to level a floor structure whose structure is multilayer. In such a situation, logs, waterproofing, and plank covering are laid on the subfloor. The next layer is DSP, providing not only a flat floor surface, but also sound insulation.
If you use DSP with a decorative front layer, you can immediately get a clean floor without the need to lay other materials on top. This material is also used for installation. When constructing utility and storage buildings, laying slabs with a thickness of 24-26 mm is allowed directly on leveled bulk soil.
Production of SIP panels from DSP
An improved version of the new generation of building materials are SIP panels, the basis of the design is DSP.In the production process, a sandwich is formed, for which insulation is placed between two cement-bonded particle boards, fixed under high pressure with glue.
The resulting structure is highly durable and does not require additional operations to insulate the building after installation. Using quality species heat-insulating layers, SIP panels are environmentally safe and resistant to fire.
