Foam concrete is very practical and cheapmaterial for the construction of private structures: houses, villas, garages. He has certain merits. Before you are going to make a foam concrete yourself, you need to understand its advantages. First of all, the material is relatively light and inexpensive. Houses constructed from such blocks, practically do not require any additional use of heaters. And the material is an excellent soundproofing, which has good resistance to negative influences.
The next advantage of the blocks is thatyou can make foam concrete with your own hands. And the procedure will not be very expensive. For work you will need sand, cement and water (to mix the solution); hardener and foaming agent. To combine all these ingredients you need a concrete mixer. Naturally, you will need forms in which you will lay out the solution, as well as a place where it can dry.
Production of foam concrete with their own hands - not difficultoccupation. The work consists of several procedures: kneading a concrete solution and a foaming agent, pouring molds and drying the finished product. During the manufacturing process, the proportions of the components should be accurately preserved. In order to obtain a block of medium density, it is necessary to dilute only 4 g of foaming agent in 1 kg of cement. If more heavy blocks are needed, the amount of concrete can be slightly larger.
So, let's take a closer look at how to manufacturefoam concrete with their own hands. For the preparation of concrete should be used high-quality cement grade M500. The sand must be fine-grained. Water should be maximally purified from various impurities. Now proceed to the preparation of the foaming agent. In principle, the substance can be made alone, but you can buy it already prepared. The mixture should be passed through the foam generator. Only after this, you can add it to the cement slurry and mix it well.
Next, we make foam concrete with our own handswith the use of hardener. A couple of minutes after mixing all the ingredients, the mass can be poured into molds. It should be noted that in this way it is possible not only to prepare separate blocks, but also to build a monolithic structure. The mold for pouring can be made of metal or plywood. The easiest option is the formwork. But at its construction it is necessary to pay attention to geometrical parameters of the form: they should be very exact, that the material turned out equal. Internal walls of the formwork should be greased with a special tool, which will not contain fat. Thus, you can easily pull out the block from the mold and subsequently coat it with plaster.
Further manufacturing of foam concrete by own handsis produced by drying the mixture at a temperature of up to 50 degrees. The process lasts about 48 hours. After this, the blocks can be removed from the molds and used in construction, and a new portion of the solution should be poured into the mold.
