Cement-chipstones (deciphering abbreviation CSP) call whole class of building materials used for different purposes.
They are made of wood chips, high-quality cement and various additives that give cement-chipboard the necessary characteristics.
You will also learn what advantages and disadvantages have cement-chip plates compared to other types of finishing materials and what builders and owners / residents of houses and apartments speak about them.
Despite the fact that the term cement-chip plate (the material is represented in the photo) you can apply to many types of building materials, in world practice this name has been fixed only for panels and blocks, relevant requirements GOST 26816-86which you can find.
Therefore, in the title of building materials made according to this standard, the GOST number is always indicated. This applies to both Russian products and stoves officially supplied to Russia from abroad.
However, conventionally to the CSP can be attributed to approximately comparable products from:
To the main technical and other characteristics that distinguish sheets of cement and chips from others belong:
The dimensions of the sheet standard are written in GOST 26816-86 and make up:
The remaining sizes do not correspond to GOST, but due to the high popularity, many enterprises producing cement-chipboard are neglected and they.
However, even when compliance with the manufacturing technology and full compliance, these plates cannot be called manufactured according to the state standard due to the difference in size.
Permissible deviations from these sizes depend on the brand and make up for:
The composition of the solution from which blocks of wood chips and cement make are not registered in GOST, however most manufacturers adhere to the following proportions:
This composition provides balance Between durability, including rigidity, and heat insulating properties.
If it is necessary to increase the strength of the product, then more cement is used, and to reduce thermal conductivity, increase the percentage of wood waste, or select the most effective shaping shape.
Changing the composition and number of additives regulate the ability to absorb water and resistance to frost. After all, the more water absorbed into the wood inside the plate, the stronger the cement stone will be damaged. Initially, due to swelling, then due to the conversion of the fluid into the ice, in which the volume of water increases by 11%.
Elasticity and tensile strength are most dependent on the length and shapes of chips, as well as compliance with wood waste treatment technologies before making them into the solution.
Violation of technology processing not only will reduce the strength of concrete stone due to the sugars contained in the wood, but also will increase absorbency shavings.
The use of irregular reagents or a strong increase in their quantity can lead to a decrease in the vapor permeability of the CSP, which will make the plates unsuitable for use in breathable houses.
The tensile strength from the cement-chipboard is small, so it cannot be used as a material that can withstand the nail or self-load with any load. However, according to this parameter of the CSP the majority exceeds Finishing materials, yielding only glass magnesite sheet (CML), so it can withstand a suspended picture, a clock, or even a shelf with light dishes.
By strength to bend, the CSP also exceeds most of the finishing materials, yielding only the CML.
All types of strength depend on:
Therefore, the material made in accordance with the requirements of GOST has higher strength indicators.
One of the important properties is a water resistance that describes the ability of the material to maintain the original humidity Even after immersion in the water for a day.
According to this parameter, the CSP is comparable to other wood-containing materials and exceeds the CML. Therefore, under normal conditions, when the material is installed vertically and goes oblique rain, water absorption is small, and it will take 10-100 hours on her evaporation.Depending on the duration of precipitation. In this regard, this material refers to a sufficient moisture resistant.
Even if frost will hit immediately after a strong and long rain, the depth of the water damaged by the layer freezing will not exceed several hundredths of the millimeter.
According to the parameter of the vapor permeability of the CSP, comparable with clay brick And a little inferior wood. Causes - in the porous structure of cement stone, as well as wood chips. So, the vapor permeability of the chips along the fiber is 0.3 mg / (m · h · pa), and the same parameter of concrete is 0.03 mg / (m · h · par).
Due to the fact that part of the pair moves through wood, the total vapor permeability coefficient is 0.08-0.1 mg / (m · h · par). In this case, the vapor permeability of wood across the fibers is 0.06-0.08 mg / (m · h · par). Therefore, shelted wooden house From the inside or outside the CSP, you do not worsen its vapor permeability and do not lush Home main advantage - dry microclimate inside rooms.
Other materials based on cement and wood waste have a similar value of vapor permeability. After all, the process of driving the water vapor through the cement stone and the tree fibers are the same regardless of the name, destination and thickness of the material.
Due to the large content of cement, the DSP density is 1100-1400 kg / m 3, which is comparable to:
Therefore, the weight of the plate with a thickness of 8 mm is 38-45 kg, the weight of the CSP sheet is 10 mm, 12 mm or 20 mm, respectively, more, and the mass of the slab with a thickness of 40 mm may exceed 200 kg.
This makes it difficult to use the CSP on the upper floors, if there is no possibility to deliver it to the top with a crane or electric shift. In addition, thick sheets hard on the ceiling, because this will require a brigade of several people and a powerful overlap.
The large mass also limits the use of this material to insulate the wooden floors, because very powerful overlaps are needed.
This parameter describes the ability of the material. transmit thermal energy through yourselfSo than it is less, the lower the heat loss. The thermal conductivity of cement-chipboard CSP-1 and CSP-2 GOST 26816-86 is 0.26 W / (m · ° C). It is comparable to such materials as:
For comparison, we give the thermal conductivity of various structural and insulation materials.
CSP-1 and CSP-2 plates are several species - with a grinding or unlipped surface. Difference between these types of products in permissible roughness.
Uncuffled possess an even, but less smooth surface. The permissible roughness size for them is 0.3 mm.
For grinding plates of CSP-1, the permissible roughness size is 0.08 mm, for the CSP-2, the maximum roughness size is 0.1 mm.
On the touch, the grinded CPSP-1 plate resembles a high-quality polished phaneer, and CSP-2 is similar to high-quality GLC. Unqualified materials resemble the usual fane or chipboard (chipboard).
The price of cement-chipboard depends on:
The material corresponding to GOST 26816-86 is always more expensive for what is made without regard to this document. To some extent specify GOST 26816-86 In the title of building materials is synonymous, regardless of the place of manufacture of plates. We have prepared a table that included the most popular CSP manufacturers and their official dealers, as well as the price per sheet of their products:

As can be seen from the table, the cost of wood cement plates or panels depends on their size, sheet thickness, and, accordingly, its weight, which we said earlier: for each indicator of thickness - be it 8mm, 10mm, 12mm, 16mm, 18mm, 20mm, 24mm or any other will be installed its price per sheet or per M2 material.
In addition, the stove is unlocked with a thickness of 10 mm or 12 mm will cost cheaper than ground similar dimensions.
When installing CSP, like any other finishing materialIt is often necessary to give it some kind of definite form.
Unlike plywood, OSP and other similar materials, CSP cannot cut with electric jigsaw.
Cement stone quickly erases the blade teeth to the full loss of the cutting ability. So for cutting this material it is advisable to use:
CSP canalso millUsing a manual milling mill or copy milling Machine, as well as a nozzle with carbide attacks. You can use a drill to drill both with conventional metal drills and with those whose tip is made of tungsten carbide.
To attach a cement-chipboard to any base, nails and rotable screws for metal are used. Under the nails, the hole is drilled for the entire length, for the screws, it is necessary to drill a deepening for a hat for a hat, slightly exceeding it in size. For lizers and house owners.
In this parameter, the CSP is superior not only polymer insulation and PVC, but even arbolit. CSP has been assigned a combustible class - G1, that is, they are challenged. Due to the large proportion of cement, each of the chips is surrounded by cement stone, so to start the pyrolysis process located close to the wood surface it is necessary to effect the temperature of 500 or more degrees for half an hour..
As soon as the thermal impact is eliminated, the pyrolysis process is quickly completed, because, for the beginning of a self-sustaining reaction, a close contact of many chips is needed.
If the temperature exceeds 700 degrees, and this effect lasts more than an hour, then the pyrolysis of chips begins across the depth of the plate.
At such a temperature, any building materials dramatically lose strength, and the concrete is completely destroyed. Therefore, after a fire of such a strength, the house is not subject to repair, except that the fire was local in nature and lied only small plot at home.
Even the beginning of the pyrolysis process does not lead to highly poisonous substancesAfter all, the main components of pyrolysis gas (smoke) is:
There is only a serious danger of carbon monoxide, but, firstly, it is very small in the process of pyrolysis, and secondly, the burning occurs in the conditions of lack of oxygen, so the carbon monoxide is allocated everywhere in huge quantities.
Therefore, CSP one of the safest In the fire plan of materials and comparable to GKK and fibroplites. He is much safer finishing from:
Due to the large content of CSP cement much hard most others Resistance to mold and disease
Due to the fact that wood in the CSP does not have direct contact with air, it is less exposed to mold and diseases.
In addition, products made in accordance with the requirements of GOST, chips are pre-soaked in the solution of lime or other reagents, enhance biological stability Woods.
Cement-chipsticks (CSP) refer to universal sheet building materials. Raw materials for cement-chipboard (CSP) - Portland cement, crushed wood chips and additives, which reduce the influence of substances contained in wood, on the formation of cement stone.
The manufacturing technology of the CSP can be briefly described as the formation of a three-layer "cake" of two types of cement-chip mixture: a mixture with a fine-chip filler forms an external layers, and with a large inner layer. Then the puff slab is molded under high pressure Hydraulic presses and gets perfect smoothness and thickness.
CSP applies:
CSP does not constitute a serious competition of fibreboard, plasterboard, GVL and backelovated plywood, due to variations of the characteristics of these sheet materials. All these plates are in demand depending on the working conditions and the required operational qualities.
Standard sizes of CSP 2.7 * 1.25 m and 3.2 * 1.25 m under gradations of thicknesses in mm 8; 10; 12; sixteen; twenty; 24 and 36.
We list the main characteristics of CSP plates:
We list the main advantages of CSP plates:
The disadvantages of CSP plates will take:
It is required to protect against atmospheric influences, it is possible for long-term storage exclusively in horizontal laying, but the CSP transport is transported in the position "on the edge".
Installation and finishing of the surface by CSP plates are carried out in the following order:
For alignment under the final finish, the CSP sheets are considered one of the best materials, due to the good stiffness and the perfect smoothness of the sheets. Finishing and alignment with CSP plates give an excellent result. Finishing materials can be paints, plastering mixes, facing tiles, wallpaper of any types, natural and artificial linoleums, laminates, plugs, soft materials Type carpet and others.
CSP is the production of widespread use, the basis of which is the basis of two different characteristics: cement having a mineral origin, and wood chips - natural organic raw materials.
Plates combine the advantages of concrete and DVP products, demonstrate greater strength and absolute environmental safety.
The TSP-panels are made in several stages, the most responsible of which is the stage of preparation of raw materials. The composition of the composite product includes the following components:
For effective enveloping two types of components, hydration, binding fillers are introduced in an amount of approximately 2%. The entire working mixture is wetted by water, the mass fraction of which should not exceed 9%.
At the stage of preparation of raw materials, chips is crushed and dissipated into two fractions. Slices with smaller sizes in the manufacture of CPSP boards will be located in the outer layers, with large parameters - in the inner core plate.
To ensure the preservation of wood raw materials for a long time, it is impregnated with solutions of aluminum salts and liquid glass. The processing ensures the durability of chips with respect to biological infection, an increase in the strength of the fibers that perform the reinforcing function in the composition of the composite.
At the next stage, the chips, the solution of additives and cement needs to be combined and mixed thoroughly, achieving a completely homogeneous mass. This can be done only with the help of special labels of high power, adjustable rotation intensity. Wood pieces are not very well covered with mineral powder from cement, so sometimes a small portion of fuel oil and industrial (technical) oil is added to the mixture.
Upon reaching the absolute homogeneity, the mixture is layered in the pallets, which waters over each other and placed under the press. After exposure to high pressure, the compressed cement-chip mass recorded in the shapes of the latches is moved to thermal chambers, where heating throughout one work shift is carried out.
Then the forms are removed from the chamber, return again under the press, where the castle clamps are removed. Formed TSP-sheets for the final gain of all performance characteristics Tolerate in warehouses, where it is kept for 2 weeks, periodically drying by air flow heated to 100 ° C.
At the final stage, the slab is formatted in size, packaged, sent to the storage room of finished products.
The national standard regulates the material unit for general physico-mechanical parameters and the size of the CSP-slabs into 2 groups. The length of the products is 3.2 and 3.6 m. In the first group, vibrations of the parameter are allowed to one or another side by 3 mm, in the second group - by 5 mm.
Standard width values \u200b\u200bare 1.2 and 1.25 m, the trend in permissible parameter oscillations is the same. Error in the geometric parameters of the product of the 2nd group is always greater.
Sheet thickness is different:
The fluctuations allowed by the thickness fluctuations are changed from 0.6 to 1.4 mm in the first group of CSP-plates and from 0.8 to 1.6 mm in the second group.
The regulations stipulate the strict perpendicularity of the intersecting sides of the plates, the normalized dimensions of the diagonals, the limited deviation from the plane, equal to the 1st group of a maximum of 0.8 mm, for the second - a maximum of 1 mm.
The standard stipulates the amount of flaws, the presence of which is permissible. Fully eliminated the possibility of the presence of chips on CSP-stoves, the number of possible spots of any origin and dents is rigidly regulated. Requirements for products with the designation of CSP-1, more rigid than to the production of CSP-2. Delamination, foreign inclusions, mechanical defects are completely excluded for the entire line of materials.
To evaluate the operational capabilities of the CPSP-sheets, the physical parameters are of defining meaning.
Plan the conditions for transportation, installation can be, knowing the weight of the CSP weight, which is determined by the size and density of products. The minimum share of cement-chipboard is 1100 kg / m 3, the maximum is 300 units greater.
As an example: one sheet with a density of 1300 kg / m 3 and dimensions of 2700 x 1250 x 10 weighs almost 44 kg (43.88).
This obvious conclusion that the material is very heavy. One cubic meter panels will weigh almost one and a half tons. The buyer must thoroughly prepare for the delivery and subsequent use of panels with such weight.
The normalized Humidity of the CSP is equal to 9%, the standard for the oscillations of the value by one third towards the increase or decrease. A sufficient large amount of possible deviations are due to the apparently features of the structure of the composite.
CPP products When conducting control tests per day, can increase in size in thickness by 2%, which is due to the absorption of moisture in an amount that can be 16% of the initial mass of the sheet. This factor must be taken into account when storing plates and install it on the front part of the house, outside industrial structures.
The presence in the composition of wood fibers made it possible to give the material good strength properties. Thus, the maximum strength in bending loads at the thick sheet is 12 MPa, in the thinnest - 7 MPa. If stretching efforts are attached on the stove, estimated at 0.35 MPa, it will not undergo changes. Since the strength of CSP-slabs is higher than that of plywood, they are actively used for the construction of formwork.
The standard is normalized by the permissible roughness of the surface, which is 4 times less for grinding panels than for unlocked. For the manufacture of formwork, it is quite possible to purchase plates that have not been grinding. The finish of the facades can be made beautiful both with the help of grinding products and by mounting the CSP-plates with a roughness that has passed additional decorative processing.
Of chemical composition And the technological features of production logically follows the high resistance of the TSP-panels to ignition, the minimum tendency equal to virtually zero to the spread of the flame. In the case of severe heating of the cement-chip material, there is a meager possibility of formation of gases and smoke when combustion. In this case, the toxicity of the allocated thermal oxidation products is very small.
Note! It is safe to say that CSP-slabs - fireproof material.
Wood chips in itself burns great, but in the composition of the composite it is impregnated with mineral means, surrounded by portions of Portland cement, which lowers fire danger to zero. The combustibility of the CSP panels in accordance with the generally accepted classification is indicated as G1.
One of the important characteristics of the CSP-slabs is frost resistance. It impresses the ability of panels made from a mixture of cement and chips, to carry frost. Even if the finish 50 times in the winter will defragment defrost, and then freezing (although such frequent temperature differences happen extremely rarely), then the coating strength will be reduced by only 10%. CSP plates can easily be operated on the street for half a century.
The production of CSP plates in Russia is implemented in industry about thirty years. During this time, domestic and foreign technologies We changed, which led to the emergence of new similar materials on the market, for example, such as:
The composition of fibrolite includes cement and so thin wood fibers that they are called wool. The material is soft to the touch, well isolates the sound, it has high strength and resistance to cracking.
Arbolit is a mixed composite consisting of cement and wood chips, chips, cickens and rice straw stems. The material is not very durable, suitable for the construction of light partitions. Unlike the CSP-slab, which is completely applicable to the floor covering, the arbolite of such a load will not stand.
The feature of xylolite is an increased resistance to water, achieved due to the introduction into the composite mass of the borders. The xylolite panels can be put on the floor, lay on the roof, are located in any places where a large amount of water is possible.
Cement-chip panels can be laid on overlappings, installed as partitions or main walls, sowing housekeys, to separate part of the walls above the foundation (base). It is known to use the CSP-slab for the floor instead of a cement screed. The material copes perfectly with the load, moreover, provides thermal insulation.
Galvanized nails of the screw shape are suitable for fastening the structures, when the length is selected, the thickness of the sheet and the total sizes of the cake should be taken into account. You can also use screw screws, which are pre-prepared by holes.
Due to the large mass of panels, special attention should be paid to compliance with the recommended distances between the attachments. To do this, it is advisable to take advantage of special tables that are compiled, taking into account the value of the sheet thickness and the location of the attachment.
In addition to fixing around the perimeter, intermediate fixments are necessarily made on the tile, usually disposed in the middle part of the height. In the gaps of the CSP, you can fix half less frequently than on the edge lines.
Format plates can be ordinary high quality toolsdesigned to work with large hardness materials.
It is not worth grinding the surface layer, because it can lead to an increase in the inclination towards the absorption of moisture. When docking wall structures, the need for altitude alignment can appear, which is somewhat more complicated than when working, for example, with bricks. In such situations, the use of any grinding machine is allowed, the main thing is that the grains be laid up to No. 25, then the design damage will not take place.
For the finishing design, the CSP surfaces are usually plastering and painted. This reduces their ability to absorb moisture. The material longer serves, does not crumble.
When working with the CSP, it is recommended to leave a sufficient distance at the junctions, which indoors should be at least 4 mm, outside - 8 mm. When you ignore this requirement, cracking of suture compounds may occur. A fairly large space is closed with elastic plastic or sealant.
Outdoor joints of the joint sometimes decorated with rails or profiles from aluminum alloys, in the joints of the joint can be laid a special elastic cord.
In the construction of private house-building, customers wishing to ensure the maximum structure fire safety, Choose a project option with the manufacture of sip-panels from CPSP-sheets. At the same time, between two plates made from a mixture of cement and chips, a inorganic insulation of mineral origin is placed. The resulting design demonstrates strength, environmental friendliness, fire safety.
When performing activities related to the improvement of apartments, a private house or implementation overhaul In new buildings there is a need for floor alignment. With limited timing of performance, it is problematic to fill the cement screed, drying over long time. The cement-block plate can significantly reduce the duration of the repair work and ensure the perfect flatness of the floor surface. Let us dwell on the characteristics, advantages and disadvantages, as well as the specifics of the use of plates.
Pursuing searching building materialThe developers probably faced the abbreviation of the CSP.
The reduction denotes a cement-chipboard made of the following components:
The production technology of the PPS panels provides for the following operations:
Due to the increased effort of pressing inside the chip-cement array, there are no voids. The resulting product, the basis of which is wood chips and portland cement, is a thin sheet with a smooth surface with high strength.
To solve various construction tasks, a CSP plate is used. The use for the floor is not the only area of \u200b\u200bapplying cement-chip plates. The advanced range of products allows you to perform the flooring of the floor for every taste.
CSP used when sheeling frame housesAt the same time, the stove serves as a bundle and facing Specifications and properties of cement-chipboard provide its competitiveness with other building materials, as well as an extended scope.
This allows you to use plates for different purposes:
The absence of harmful reagents in the cooker allows you to separate production and residential premises. The garage and workshop after decoration panels of the CSP will acquire a modern view. It is well applied to the CSP panels Tile plaster, subject to the use of a reinforcing mesh of plastic.
The chip-cement panels are used in construction to solve a complex of tasks, significantly reducing the laboriousness of work compared to traditional methods. Modern building material not only reduces labor costs, but also reduces the estimated cost of building events.
The advantages of building materials affect the manufacturing technology and the composition of the CSP plate, consisting mainly of cement and chips. What are they going to?
Frame for CSP need a serious, capable of withstanding heavy loads Compared with traditional chipboard plates modern material It has improved features:
The CSP plate is used in various climatic zones, while maintaining performance properties.
With a width of sheets, equal to 125 cm, the plates differ overall dimensions and other characteristics:
CSP slabs for sex when absorbing moisture as a result of an unexpected situation, no more than 2% swell, which is extremely insignificant. Depending on the peculiarities of the application, the plates are made with a rough and smooth surface. The properties of the panels allow you to lay on the surface of various types of fixed coating, as well as paints and varnishes.
The cement-chipboard is wood chips (respectively, and positioned as a chipboard), compressable and treated cement mortar Cement plates for the floor, like other building materials, have advantages and have weaknesses. Main advantages:
Weak sides of the plates:
Recently, more and more often used as the foundation for the finishing finish Due to the serious complex of advantages, chip-cement plates are popular in the construction sector. For most characteristics, the sheet building materials successfully competes with chipboard, wood-fibrous panels and plasterboard. Having preferred the CSP slates, it is easy to quickly perform installation and save finances.
When solving problems on the insulation of buildings of the CSP plate, the slab is used as a trim material.
Its fastening is carried out using hardware. The casing is made from different sides:
Decorative finish can be performed immediately after the completion of the installation measures.
The main advantages of the CSP are considered high strength and durability The use of building materials is to lay the finished panels on different kinds Reasons:
On the surface of the slabs can be glued ceramic tile, Shag flooring, as well as laminate or parquet. The properties of the material are preserved for decades, subject to the compliance with the installation technology.
The cement-chip plate is chosen depending on the complexity of solved tasks:
By purchasing floor slabs, pay attention to the following points:
Check also the availability of a sanitary and hygienic certificate confirming the environmental purity and harmlessness of products.
The surface of the cement plate is smooth and smooth, due to which it is very popular with the finishers using it as a base for decorative finish The process of preparing the surface for the formation of a draft base from the CSP panels is simple and is to perform the following events:
The optimal solution is laying the plates on the bars with an interval between the supports of 50-100 cm. When installing panels, the waterproofing material should be put on the lags and perform thermal insulation.
To perform work, prepare materials and tools:
After completing the preparatory activities, proceed to the flooring.
To avoid deformation during operation, there are gaps between the plates Consider how it stacked on the balcony of the CSP plate. Observe the sequence of actions:
At the final stage, it is important to carefully close the seams using adhesive composition.
When performing work, follow the following recommendations:
Pay attention also to the correctness of the preliminary cutting of the material before the start of work.
The CSP plate facilitates the formation of smooth bases, will reduce the duration of work and reduce the amount of costs. Using building materials, it is easy to build overlaps for the house of foam blocks. Thinking, consider the use of CSP panels. Using the plates can be performed. Such basis and Swedish foundation Plate. Comparison on thermal insulation properties. By construction, it is worth examining the difference of PC plates from PB. It is possible that it will be useful when choosing a material.
Not so long ago in the country (in the USSR since 1987) the production of CSPs is deployed. What the cement-chipboard is found. Application in modern construction And what are they present?
CSP - sheet composite material, for the manufacture of which is used average and thin woody (24%) chips, portland cement M500 brand (65%), special chemical additives (2.5%) to reduce negative impact Wood extracts for cement, and water (8.5%) (image 1). Get plates with pressing at a temperature of 900 ° C for 8 hours. After that, products are maintained under natural conditions for 2 weeks.
The most famous domestic manufacturer is Tambov Tamak plant. Plates also produce CPSP Svir (St. Petersburg), Kostroma TsSP plant, Omsk Slopjan, Tyumen Sibzhilstroy and building structural buildings located in Sterlitamak.
Russian products meets the requirements of GOST 26816-86. It is divided into 2 stamps: CSP-1, TSP-2. Less stringent requirements are allowed to sheets of the last brand than to the CSP-1.
Cement-chip plates possess:
But cement-chipboard, specifications which are generally good, have a number of shortcomings:
The versatility of the slab allows them to be used to solve various construction tasks.
First of all, it is outdoor work: construction frame buildings, Facade finish residential houses, warehouse and agricultural premises, use as a basis for a soft roof, fencing balconies and loggias, application as failure formwork For foundation.
Facing facing (image 4) is carried out by fastening cement-pall sheets with nails, screws, metal brackets, or screws on a frame made of wooden bars or metal profiles. The optimal shaft step is 60 cm, the bars are preferable to mount vertically, with small areas you can use horizontal mounting. There are 4-5 mm gaps between the sheets, which prevent their deformation when the air temperature changes. The filler of the gaps is the elastic mastic or the sealing gasket, which are closed with nicknaps with nachchelniki outside the outside. The space between the wall and plates, depending on the purpose of the building, can be left blank, and you can fill in a modern insulation, for residential buildings it is very relevant. After fasteners, the sheets are ground and applied decorative plaster Or just paint.
In the manufacture of the base for a soft roof, you should pay special attention to the waterproofing of the joints. Technologically, the process of manufacturing the basis of the CSP is similar to working with wood materials.
For the fencing of balconies and loggia, the cement-chip plates are much more expedient to use asbotic sheets, because instead of a fragile material, a solid and durable fence is being built.
Formwork from CSP (image 5) is increasingly used in construction low-rise buildings. It provides:
Due to the complete absence of the allocation of any harmful gases and vapors during operation, cement-chipboard plates are recommended for interior decoration of the premises (image 6): They align the walls (fasten either on the frame from the most rigid reinforced profile, or on a special solution or mastic) , form internal partitions, especially in conditions high humidity (To increase the service life, such a partition should be treated with water repellent and paint waterproof).
CSP slabs and for floors are used (image 7), and their use is preferable to the use of wood-piping (chipboard) or oriented chips (OSP). Typically, the laying of the CSP for the floor is carried out on lags having a cross-section of 50x80 mm, with a pitch of 600 mm.
With the help of the CSP, you can:
CSP thickness is:
Cement-chipboard can be safely recommended to perform the above work. But it is necessary to use the products of the domestic producer, and the Chinese CSP does not acquire. The use of products of hardworking Asians can lead to swelling of the plates, their coloring, the sheets themselves can be curves, and the surface is uneven.
