CBPB stands for cement particle board. In our time, it is quite sought after building material. Usually it is used in special technology "dry mounting". Of all the wood-cement products it has the largest density. These boards combine the best characteristics of wood and cement. Characterized by excellent resistance to external negative factors can not be influenced by mold, much to stand out from its competitors. In This product consists of a variety of chemical additives that are required for mineralization of chips. This protects the wood components from erosion and decay. Thanks to these figures they are often used in outdoor applications, as well as in areas with excessive levels of humidity. CBPB can change their properties under the influence of moisture, but these changes are very minor. However, in practice this point is taken into account by designers and builders. Performing works on finishing horizontal surfaces (ceilings, floors), gaps between the boards do not leave. If edged vertical openings, such as half-timbered houses, you need to do tile gap of a width of 3-5 mm. They are left after each 1.25 m wide plate. Inch gap around the perimeter is laying slabs. Ramps sizes do not affect the service life and quality of cement particle board.

The feedstock for the manufacture of cement particle board represented by the following components: chips (small and medium sizes), aqueous solutions of various chemical additives (calcium chloride, aluminum chloride, aluminum sulfate, etc.). Chips treated mineralizing additives in a blender, then add the water and cement. Percentage of components include chips - 24, cement - 65, Chemistry - 2.5, water - 8.5. Technological process involves forming multiple layers. Each of them consists of chips of various sizes. At the final stage, the pressing plate. CBPB is a monolithic structure, it is not subject to delamination. Such technology allows to produce products that have a smooth gray surface, which is immediately ready for finishing work (priming, painting). In this preliminary alignment filler is needed. The thermal conductivity characterizes thermal insulation material. This is a very important indicator of building structures. Thanks to the peculiarities of production technology (organic compound cement and wood) CBPB has virtually no air inclusions. This provides excellent thermal conductivity data plates. That is why their main field of application is focused on the specific conditions where high strength of the material and its low thermal resistance.

CBPBs are characterized by excellent sound performance. They are suitable for wall framing with ceilings and light walls. The most effective protection from external noise will mix cement particle board, mineral wool. Specially developed standards and rules define the requirements for the fire safety of any building project. Design principles directly related to its purpose. This documentation contains a specific set of rules to the level of fire resistance and fire protection qualities of construction materials used. These indicators are given in a separate directory. They are needed to assess the fire safety of individual structures, as well as the whole building. According to documents CBPBs have a category of flammability G1. This is confirmed by a special certificate of conformity (GOST 26816-86).

If we consider the environmental safety, the cement-bonded products are absolutely flawless in this regard. It does not emit any toxic or hazardous substances into the environment. As products not shield electromagnetic fields, not electrified, and belong to the warm material. Among other things biosecurity CBPB is also on a high level. Pet rodents, various fungi and insects do not pose any real threat. This high biological stability does not achieved due to the introduction of the various antiseptic agents.

Pet rodents, various fungi and insects do not pose any real threat. This high biological stability does not achieved due to the introduction of the various antiseptic agents.

The outer covering is also not play any role. The thing is that the antiseptic is naturally produced in the plate itself, as during hardening of cement and turning it into a concrete-product is released, which is calcium hydroxide. It is this substance and creates an alkaline environment, which in turn prevents the negative external influences. It turns out that a relatively simple manufacturing technology automatically makes CBPB completely non-toxic antiseptic, and the demand for these materials is very high. Thus, we can conclude that these plates are suitable for almost any installation work building direction. They are widely used in precast structures and facades. Also they can be coated ceilings, walls and walkways. Erect fences of them and containers. The strength of the CBPB is not related to the direction of load on it. It turns out that it can be fixed without any concern as to the horizontal and vertical. Plate quite easily handled, despite their high strength. For exterior cement-based panels are widely used different color formulations based on silicone or acrylic. They can be applied in one coat, and in a few. It all depends on the type of paint and the personal preferences of the customer. The coating is applied to a dry surface, which pre-primed. All faces and cooktop primed necessarily even if they will not in the future be covered exterior trim.

Material - cement-bonded particle boards have a number of characteristics that favorably distinguishes them from other building materials. CBPB plate high-strength material, resistant to the environment, not only susceptible to the effects of mold.
Plates CBPBs are made of cement and wood chips. For mineralization of wood chips added chemical additives. These chemical additives protect the wood chips from decay and erosion. CBPB plate in slightly changes its linear properties, depending on the ambient humidity. Consider this point builders and designers in construction practice. When plating vertical openings fachwerk must leave gaps of 3-5 mm after each 1250 mm wide slabs CBPB. When installing the board in the horizontal - floors, ceilings, slabs stacked without gap between them. Clearance of 10 mm is on the perimeter of the square paving slabs. Linear operational changes do not affect the size of the quality and durability of the CBPB


Thermal conductivity of the material, characterized by thermal conductivity, is a key indicator of construction materials. CBPB Group's organic mix of wood and cement, are nearly solid, no air inclusions material, which ensures good thermal conductivity. Therefore, the greatest use of CBPBs found in konstruhtsiyah that require a combination of high strength and low thermal resistance of the material.

sound insulation properties

CBPBs have excellent sound quality and are suitable for cladding light partitions, walls and ceilings. In combination with mineral wool CBPB can be used as an effective means of protection against noise.


Behaviour in fire

Requirements for fire safety of buildings accordance with relevant rules and regulations, which, depending on the purpose of reserve design principles, as objects, and individual designs are specific requirements for fire resistance and fire protection properties of the construction materials used. Fire resistance of building structures is in a separate directory. On the basis of these data according to specific procedures is assessed fire protection of building structures and facilities in general.

Determination of flammability cement bonded particle boards is determined by the Building Code according 21/01/97. According to this document, CBPBs are classified as G1 (combustible), which is confirmed by the certificate of conformity - ¹ ROSS RU. SL25. N00011 GOST 26816-86 (GOST 26816-86 quote from: "... plates belong to the G1, nonflammable materials increased biological resistance and are intended for use in the construction of wall panels, floor panels, in the elements of false ceilings, ventilation ducts, in arranging the sexes and as well as drip boards, cladding, coating parts and other construction products ...

Comparative characteristics of the main wood-board materials.

Range of trees and wood-based materials is quite wide. Definitely say which one is better, not because of their different destinations. CBPB features underscore their basic properties. We give a brief description of these plates.

Plywood of coniferous and hardwood laminate is glued structures consisting of three or more sheets of wood with a mutually perpendicular direction of the grain in adjacent layers, which provides increased strength in all directions. Surface is treated in different ways: laminated, coated planed veneer, paints, varnishes. Plywood used in the construction, interior finish, trim and interior design in the furniture industry.

MDF panels - one of the most environmentally friendly materials with low (or zero) in formaldehyde. It serve as the basis for the board MDF (Middle density fireboard, or MDF - medium density fibreboard), impregnated with a special compound that increases their water resistance. Cover - decorative films on paper. The panels are designed for interior design, interior walls and ceilings in homes, offices, office space.

Chipboard (OSB) is produced by hot-pressing of wood chips. They are glued with synthetic adhesives, such as carbamide-formaldehyde, melamine-formaldehyde carbamide and phenol-formaldehyde. Due to the excellent mechanical properties of particleboard suitable as flooring on joists or floating. Laminated or covered with natural veneer plate is used in the manufacture of elements of kitchens, dining rooms and bedrooms. But for all sorts of CBPB to exclude the possibility of direct moisture. Wood board is resistant to insect, but is subject to fungal mold prolonged moisture.

Plate OSB (Oriented Strand Board) - a product of pressing the rectangular flat chip under high pressure and temperature. Bonding base is waterproof fenolomochevino-formaldehyde resin. The properties of these plates caused the current stacking chips. It is placed in a particular order: the outer layers - in parallel to the length of the plate in the interior - perpendicular.
These plates due to its parameters (resistance to moisture, low water absorption and a slight swelling) are indispensable in the skeletal construction of houses.
