Technology of manufacturing of arbolite. Arbolite: production technology, composition
Manufacture of building materials ontoday is a very profitable industry. This is due to the high demand for everything related to the erection of buildings. All developers are trying to apply and tested materials and introduce new technologies that will be less expensive in cost and more practical in application.
Despite the huge range of constructionblocks, huge popularity began to use and arbolit. The technology of its production depends on the conditions under which it is made. The material itself has excellent performance properties and characteristics.
What is arbolite?
This is a building material that is produced inform of blocks. They have a certain size and composition. Due to the fact that natural raw materials are used in its production, it has excellent technical characteristics.
Methods of production of arbolitic blocks
Arbolite manufacturing technology can be applied:
- in factory production;
- at home manufacture.
Raw materials for production of arbolite
The technology of manufacturing arbolite is characterized by the use of certain materials:
- concrete 400 or 500;
- chemical additive;
- organic filler.
There are some recommendations for choosing raw materials. For example, concrete needs to buy one that is made on the basis of an astringent. It is also possible to use concrete of higher strength. As a chemical additive use liquid glass, chloride or calcium nitrate. Organic fillers: wood shavings, crushed stems of cotton, crushed rice straws and much more.
Arbolite, whose production technology is distinguished by the use of certain means, can have a different specific weight. For example, blocks having a density of less than 500 kg / m3 refer to the group of heat-insulating arbolite. And those that have a density of more than 500 kg / m3, belong to the group of structural blocks.
Accordingly, the first variant of the arbolite is most often used for the construction of interior partitions, but the second one is the bearing arbolitic structures.
Stages of material production
The technology of manufacturing of arbolite consists of several stages:
- preparation of a certain amount of organic aggregate;
- work on soaking wood chips in a solution of calcium chloride;
- dosing certain components of the arbolite;
- directly manufacturing blocks.
Preparation of organic aggregate
Any production of building materialsis characterized by preliminary preparation of all necessary raw materials. Wood in bars is crushed and formed into certain heaps. They should be put under a canopy and withstand at an optimum outside temperature of +15 ... + 25 degrees for about 1 month. After that, the wood is crushed in special equipment on a chip.
Only this action should be approachedresponsibly. Chips have their own specific faction. It depends on it the quality of the arbolite mixture. A sliver of 10-20 mm in size characterizes the fractional composition in 70%, 5-10 mm is already attributed to 30% of the fraction.
Soaking the wood and preparing a solution of calcium chloride
The chips produced during the crushing process are necessarysoak in the water. The temperature of the liquid must be at least +20 degrees. The whole soaking process lasts up to 6 hours. All these actions help to increase the strength of the arbolitic blocks. It is necessary to constantly monitor the water content of the wood. The moisture content of the raw materials should be no more than 30%.
At the end of this time, a previously prepared calcium chloride solution is poured into the liquid tank. The foaming agent is sent to the same capacity.
Dosing the components of the future building material
An important stage of technologythe production of arbolite, is the correct dosing of all components. It is on this depends the quality of the arbolitic blocks and its index of strength. The dosage of crushed soaked chips should take into account the moisture content of the raw materials. All ingredients are weighed and dosed according to certain established parameters (GOST). You can use special equipment for this process. It should be taken into account that it is quite expensive, and in a non-commercial production it is not worthwhile to buy it.
The process of making blocks
It is necessary to prepare a specializedequipment for arbolita. To it at the stage of mixing the ingredients include concrete mixers and other devices that can mix high-quality mixtures and bring them to a certain consistency.
A big role is played by the order of the bookmarkcomponents. Initially, the prepared wood chips are covered. Then - cement. After that, water and chemical fillers are poured. They can change places in production. Who will be comfortable. Only the flow of all liquids should be passed through a special flowmeter.
Then mixing of raw materials takes place. It is necessary to stir until the mixture becomes homogeneous.
It is necessary to prepare molds for blocks in advance. As a rule, they are wooden, and the dimensions can be any. Inside it around the perimeter is laid out linoleum. It will allow after freezing the mixture to freely pull the block out of the mold. Also, its surface is coated with a special agent.
Quite often at homeArbolitic blocks are used vibrating table. It allows you to evenly distribute the mixture. After that, the molds filled with the composition are exposed under the canopy and are there until it is completely solidified. In some cases, certain additives are used, which help to shorten the curing time of the cement compound.
The construction of the arbolite, which is made inat home, can only be carried out after a certain period, usually after 14-20 days. During this time, the blocks completely harden, dry and will be ready for laying.
