Opilkobeton is one of the varieties of lightweight concrete, which have a low density. This building material is attributed to such advantages: fire resistance, environmental safety, strength, frost resistance, heat engineering indicators, affordable cost, vapor permeability.
You can make opalcobeton with your own hands. This requires a certain set of components. The advantage of the materials that are part of the sawdust concrete is that they do not need to be harvested in advance. All that is required for this, you can buy in construction stores or markets. You can start harvesting the day before the work starts.
To make the sawdust concrete with their own hands, it is necessary to mix the components. This is a rather laborious process, so it is advisable to use a concrete mixer. First, you need to pass through a sieve dried filings, its cells should be 10x10 millimeters. Then mix the sawdust with cement and sand. At the next step, add lime or clay dough to the mixture, and then mix it thoroughly again.
In the resulting mixture through the watering can be gradually added water, and the mixture should be mixed after each topping. In case of correct preparation of the mixture, when squeezing it, a plastic lump should form in the fist, where dents from the fingers will be visible, and there will be no drops of water. It is on this basis that the readiness of the composition is determined. Then you can form it into blocks. To hesitate in this matter is not necessary, since the mixture begins to harden literally after an hour and a half. When stacked in a mold, it should be carefully tamped, since the presence of air is unacceptable.
If you decide to do opilkobeton with your own hands, then you should know what size the blocks should be. There is a direct dependence on the thickness of the walls, the width of the openings and piers, the method of laying and other factors. It is quite convenient to build a house of blocks with your own hands, while the width of the piers or the length of the section of the wall must be a multiple of the size of the blocks. In thickness, they are usually equal to two thicknesses of red brick, taking into account the solution laid between them.
The sawdust concrete with its own hands dries long enough, especially if it is formed into blocks of large sizes. Acceleration of the process is provided by the holes made, due to which its heat-insulating properties are improved. Of these materials we build ourselves. At low tide, the form is not removed from them immediately, but after 3-5 days. To speed up the creation of the required number of blocks, many forms must be made to form building materials continuously. Forms must be detachable, which allows you to collect and disassemble them as quickly as possible. In the process of drying, block shrinkage is observed, so the molds are larger in size than necessary. The difference is about ten percent.
As you can see, there are no special difficulties in the independent production of this building material.
