The production of building materials today is a fairly profitable industry. This is due to the high demand for everything related to the construction of buildings. All developers try to use proven materials and introduce new technologies that will be less costly and more practical to use.
Despite the huge assortment of building blocks, arbolite became very popular. Its production technology depends on the conditions under which it is manufactured. The material itself has excellent performance and characteristics.
What is arbolite?
This is a building material, which is produced in the form of blocks. They have a certain size and composition. Due to the fact that its production uses natural raw materials, it has excellent technical characteristics.
Methods for the production of arbolite blocks
Arbolite manufacturing technology can be applied:
- in factory production;
- at home manufacturing.
Raw materials for the production of wood concrete
The manufacturing technology of wood concrete is characterized by the use of certain materials:
- concrete grade 400 or 500;
- chemical additive;
- organic aggregate.
There are some recommendations for choosing raw materials. For example, you need to buy concrete that is made on the basis of a binder. Concrete of higher strength can also be used. As a chemical additive, water glass, chloride or calcium nitrate is used. Organic fillers: wood chips, crushed cotton stalks, crushed rice straws and much more.
Arbolit, the production technology of which is characterized by the use of certain means, can have a different specific gravity. For example, blocks having a density of less than 500 kg / m 3 belong to the group of heat-insulating wood concrete. And those that have a density of more than 500 kg / m 3 already belong to the group of construction blocks.
Accordingly, the first version of arbolit is most often used for the construction of interior partitions, but load-bearing arbolite structures are built from the second.
Material manufacturing steps
The manufacturing technology of arbolite consists of several stages:
- preparing a certain amount of organic aggregate;
- soaking wood chips in a solution of calcium chloride;
- dosing of certain components of arbolit;
- directly manufacturing blocks.
Organic aggregate preparation
Any production of building materials is characterized by preliminary preparation of all necessary raw materials. The wood in the bars is crushed and formed into specific piles. They must be put under a canopy and maintained at an optimum outside temperature of +15 ... + 25 degrees for about 1 month. After that, the wood is chopped in special equipment for sliver.
Only such an action must be approached responsibly. Chips have their own specific fraction. The quality of the arbolite mixture depends on it. A sliver of 10-20 mm in size characterizes a fractional composition of 70%, 5-10 mm is already attributed to 30% of the fraction.
Soaking wood and preparing a solution of calcium chloride
The chips obtained during crushing must be soaked in water. The temperature of the liquid should be at least +20 degrees. The whole soaking process lasts up to 6 hours. All these actions help to increase the strength of arbolite blocks. It is necessary to constantly monitor the filling of wood with water. Humidity of the obtained raw materials should be no more than 30%.
After this time, a previously prepared solution of calcium chloride is poured into the liquid tank. A foaming agent is sent to the same container.
Dosing of future building materials
An important stage that arbolite manufacturing technology has is the proper dosing of all components. The quality of arbolite blocks and its strength indicator depend on this. The dosage of the crushed soaked chips should take into account the moisture content of the raw materials. All ingredients are weighed and dosed according to certain specified parameters (GOST). You can use special equipment for this process. It must be borne in mind that it is quite expensive, and in conditions of non-commercial production it is not advisable to buy it.
Block Making Process
It is necessary to prepare specialized equipment for wood concrete. Concrete mixers and other devices that can mix high-density mixtures and bring them to a certain consistency are referred to it at the stage of mixing the ingredients.
A major role is played by the order of bookmarking the components. Initially, prepared wood chips fall asleep. Then - cement. After that, water and chemical fillers are poured. They can change places in production. To whom it will be convenient. Only the supply of all liquids should be passed through a special flow meter.
Next is the mixing of raw materials. It is necessary to mix until the mixture becomes homogeneous.
It is necessary to make molds for blocks in advance. As a rule, they are wooden, and the sizes can be any. Inside it, linoleum is laid out around the entire perimeter. It will make it possible after the mixture has hardened to freely pull the block out of the mold. Also its surface is coated with a special tool.
Quite often, at home, the manufacture of arbolite blocks uses a vibrating table. It allows you to evenly distribute the mixture. After that, the molds filled with the composition are exposed to the canopy and are there until they solidify completely. In some cases, certain additives are used that help reduce the hardening time of the cement composition.
Construction from wood concrete, which is made at home, can be carried out only after a certain period of time, usually after 14-20 days. During this time, the blocks will completely harden, dry out and be ready for masonry.
