What to saw a cement-bonded particleboard at home

The main technical characteristics of cement-bonded particleboards

To understand how to mount the cement-bonded particleboard on the facade of a country house and what it can be finished with, it is necessary to understand what this material is. The composition of cement-bonded particleboard consists of: cement (binder, about 65%), wood chips (24%), water (necessary for hydration of the mixture) and special mineral additives. The mixture is formed in the manufacture by pressing, and as a result, the output boards are obtained with a strictly defined geometry and thickness.

Advantages of the cement-bonded particleboard, for example, in comparison with OSB (oriented strand boards) include fire safety (combustibility group C1, flammability group B1, slow-burning material). The cement-bonded particleboard also does not spread flame and has a low smoke-forming capacity. Cement-bonded particleboard is an environmentally friendly material.к. it does not contain phenolic adhesives or harmful chemicals. Cement-bonded particleboard has high strength, does not rot, resistant to the negative effects of moisture and harmful atmospheric influences.

All the listed properties open up wide possibilities to use this material, e.g. as wall cladding, construction of interior partitions, flooring, creation of shuttering for foundations, etc.д. But a change in moisture levels (even if only slight) leads to a change in the linear geometry of the boards. Therefore when installing the cement-bonded particleboard on the facade of a country house an expansion gap (4 to 8 mm) should be left between the boards.

Also, novice builders have a question, whether the impact of moisture will not cause the boards to warp. After all, cement-bonded particleboard “works” on the facade, and any compression or stretching of the boards will be reflected in the finish coat.

I clad my frame house with cement-bonded particleboards with a thickness of 10 mm. Measured the width of the gap between the sheets throughout the year. It has not changed a millimeter. In the future, I will finish the facade under the half-timbered walls with imitation of fiber-cement siding. Pretty low cost option.

The moisture resistance of cement-bonded particleboard is confirmed by portal member Nagel_Johansson. According to the user, he clad a frame house with cement-bonded particleboards. There was no exterior finish, and it rained on the corner of the facade for two days and got wet snow. If you run your hand over the outer surface of the board, it’s wet and seems to be soaked through. Nagel_Johansson checked the sheathing from the inside of the house, the sheet was dry, without any water stains or streaks.

What to saw the cement-bonded particleboard

Trading centers and warehouses of construction materials sometimes offer a sawing service. However, it is inconvenient and impractical to do this, because you would have to adjust the sheets to the exact dimensions on site.

Cement-bonded particleboard can be cut at home with the following tools:

Electric jigsaw

The tool is suitable for cutting 10 or 12 mm thick cement-bonded particleboards. Bimetal saws, designed for cutting Cement-bonded particleboard or asbestos-cement slate, are purchased for work. Use and diamond-coated samples for cutting ceramic tiles.

The usual saw for wood or metal is able to penetrate no more than 20-30 cm, after which the teeth of the tool are ground.

The board will be less dusty when cutting if you moisten the surface before working.

To get even edges, choose the jigsaw operating mode at maximum rpm with the roller turned off.

angle grinder

Angle grinder is suitable if the quality of the edge is not high requirements. It is inconvenient to cut a cement-bonded particleboard panel evenly with an angle grinder because there is no support platform. The work requires great physical strength and care.

A lot of dust is released when cutting, protective equipment must be used. In addition to goggles and a respirator, you must wear thick protective gloves. chips fly out from under the tool at high speed and can injure your hands.

Use a diamond-coated disc for cutting stone or concrete. Adjust the cutting speed to the power tool’s specifications.

In the case of a large amount of work choose an angle grinder with power from 2000 watts. it will allow you to work for a full work shift. Difficulties in sawing are the plasticity of the material, the disc is blocked, the motor overheats from the increased load.

  • Prepare a bed of several pieces of wood, laid on a flat surface. Ensure that the thickness of the backing plate does not touch the floor.
  • Lay the cement-bonded particleboard sheet on the prepared substrate.
  • Marking is done with a marker, construction pencil, or narrow crayon.
  • Spray water along the mowing line of the cut, or moisten the surface with a brush, a sponge, any other suitable method.
  • Cutting Cement-bonded particleboard begins from the edge to the middle.
  • If necessary, the other side of the sheet is cut and finished.

If there is a long clearance between the supports, the plate is not walked on, machining is performed from the accessible side.

Circular saw

the hand-held circular saw is the most suitable tool for cutting cement-bonded particleboard.

Cutting boards with a circular saw is convenient for reasons:

  • there is a support platform that allows the tool to be firmly fixed on the surface, which rules out chipping;
  • On most models there is a nozzle for connecting a vacuum cleaner;
  • The blade guard prevents injury;
  • the guide allows you to get an accurate straight cut;
  • The tool is distinguished by its productivity.

Power of the saw is chosen based on the amount of work to be done.

Purchase a saw blade for working with stone or concrete. Abrasive tools with carbide tipped teeth take precedence.

The algorithm of work with a circular saw is similar to how work with an angle grinder.

The structure and composition of the material impose restrictions on working with the boards.Its heavy weight makes it impossible to work without an assistant. Unloading should preferably be mechanized or involve 2-3 helpers.

Brittleness Cement-bonded particleboard causes the board to break when accidentally dropped. Additional work and consumables will be required to finish the broken sheet.

High density makes the sheets strong, but the cutting tools are not suitable for wood products.

Insufficient bending strength does not allow the use of cement-bonded particleboard in structures with lateral loading, such as making sloping walls without support.

The boards cannot be shifted horizontally, they may break under their own weight. Stacking products on a flat base.

Dustiness when sawing involves, if possible, working in an open space with the use of personal protective equipment. respirators and safety goggles.

High coefficient of thermal expansion forces to leave gaps in the joints and adjacencies Cement-bonded particleboard to the walls. Cement and hard fillers are not used for caulking.

Features of manufacturing and the main advantages of this group of products

As you can understand from the name, the basis of manufacture is cement and shavings, let’s consider the composition in a little more detail:

  • High quality Portland cement of M-500 grade and above occupies 65% of the volume of the finished product. It gives the sheets the highest strength and resistance to loads, it is important to use only quality cement.
  • About 24 percent is wood chips that are passed through special shredders, which separate them into pieces 3-5 millimeters wide and 20 centimeters or longer. This component gives the product high acoustic and thermal insulation properties, in addition. the wood is a renewable eco-friendly natural material.
  • Approximately 2.5% is occupied by liquid glass, which is used for timber treatment and gives it high resistance to moisture and mold. Without this treatment, the wood in the composition would soon begin to deteriorate.
  • And finally, about 8.5% is water. As you know, moisture is in all materials and cement-bonded particleboard is no exception.

Application

According to the technology of manufacture there are 3 types of cement-bonded particleboard: fiberboard, arbolite and xylolite.

Fiberboard is characterized by the use of long wooden fibers up to 50 cm. Thanks to this core, the boards gain extra strength. the fibres reinforce the material. Fiberboard perfectly absorbs sound and has low thermal conductivity, so it can be used as additional sound and thermal insulation.

Arbolite. as a filler they use sawdust and wood chips, cut reeds and rice straw. The material is used only in unloaded structures.

Xylolite is distinguished by the fact that the binding agent is Sorel cement, thanks to which the material is resistant to moisture and can be used in appropriate conditions.

  • Material with a density above 1000 kg/m³ is suitable for the construction of non-load-bearing partitions;
  • insulation of exterior walls with the installation of sheets both inside and outside the building
  • Thermal insulation of floors, floors, attics;
  • sound insulation between rooms;
  • Alignment of uneven walls, floors, ceilings before the finish trim;
  • production of fixed heat insulation boards for foundations and basement floors;
  • Fencing with the function of insulating beds and flower beds in homestead plots.

In all cases, it will be necessary to adjust the Cement-bonded particleboard to the required dimensions by cutting with further processing.
