And what penobeton? His positive technical properties of foam concrete required internal cellular structure, reminiscent of aerated chocolate. Moreover, each air cavity, as the compartment of the submarine, hermetically separated from neighboring cells. As a result, water does not seep inside. But still it is not important. Through all of the same cellular foam concrete has good heat and sound insulator: in a house from foam and warm in winter, cool in summer and at any time of year - quietly. Walls and walls of the foam perfectly tolerate temperature changes. They "breathe" and do not sweat. Microclimate in the porous concrete buildings is the same as in the wooden houses. Moreover, this material is environmentally friendly and fire: he made something out of cement and sand, and therefore, simply have nothing to burn. All this is certainly interesting and important. But I was worried about something else: can you build a house out of foam and how to do this? Employees TSNKB explained that the foam concrete is suitable for all types of construction: both the public and private. And wish to have your own house can do "little blood" and in a financial sense, and in the sense of time. Should only have the equipment. Here we must add the important thing: this equipment is not cheap - about 7 thousand dollars. Most likely, this price summer resident discourage any desire to build a house out of foam. But do not despair: a way out of this situation is - need to find a company that has a plant for making foam. Its staff will arrive on site, bring the equipment and start building a house. If you still want to acquire their own equipment, then the profitability will "chip in" with neighbors and buy a unit in clubbing. Mathematical calculations If funds are insufficient, you can build a house out of foam in parts In general, without a special unit foam concrete does not prepare, and, therefore, nothing to build. Then it's time to do calculations to determine how much it will cost us a house of foam. We start from the fact that building a wall for the house, for example, measuring 6 x 6 m. It should first be defined with architectural solution. Suppose you have selected the project. What's next? As you know, building a house begins with the foundation. The pleasure in these times do not come cheap - about $ 2000 to lay out. After working as a foundation and make it "stand", you can begin construction. To do this, buy "raw" (cement and sand), to pump water from wells, and to invite a team of workers with foam concrete plant. In the end, all about everything goes somewhere 2000 - 2500 $ (building materials plus work). Add to this $ 2000 for the foundation. Thus, the home of foam, which was built using monolithic removable formwork, cost about 4000 - 4500 $, and the house of pre-engineered - 1,5-2 times more. This amount, in any case less than the price for the construction of a brick, and even a wooden house. In addition, it is possible to build parts: first, the wall, then wall, then the roof. Incidentally, in the foamed concrete can hammer nails, it is very easy to paint and even ordinary hacksaw to cut. So the wall can be reduced, simply cut off. A reminder that if you decide to use a monolithic stacking of concrete panel or decides to lay down their house of ready-made foam concrete blocks, construction costs will increase significantly. So before making a decision, is to weigh all the pros and cons. Are there internal walls of the foam? There. At this time we were talking, so to speak, of "external walls". But because foam is quite possible to build a great room dividers. Thus they are much better than the walls of drywall or bricks. For example, if you want to make alterations, then put a new brick wall is very risky and inconvenient. It is risky, because your closing such a weight may simply not survive. A convenient, because in the process of "brick" the work will be a lot of dirt, construction dust and debris. As for drywall, just to bar them little room - it's not a wall. First, you need special guides, which are strengthened two sheets of drywall in parallel to each other. Secondly, between them should have to pave some noise isolation! And thirdly, on a wall is not recommended to hang anything heavier than photos of favorite dog - a serious workload wall may simply not survive. So, foam concrete has successfully met all of these tasks: the process of its production is much "cleaner", and moreover, the wall is obtained from this material is light, sturdy and reliable. Moreover, if you want out of it you can even make a pillow (a kind of podium) for the bed or more, as they say designers, "somehow solve the original design of residential space. The recipe of foam Manufacturing technology of foam concrete is quite simple and something even like cooking a cake. First knead "dough" made of cement, sand and water (and in some cases instead of sand added to polystyrene beads (if the material is obtained more easily). Then, in a homogeneous mass added to the finished foam, which makes the foam concrete and porous. "Dough" is ready, you can create wall blocks, floor slabs, fencing structures. In modern conditions the foam produced from penokontsentrata. It is produced industrially. To prepare the foam requires special equipment, such as foam generator or small-sized installation (sm.chertezh), which is not only "churn" foam, but also mixed with cement mortar. Adding to install a hose can be submitted (to transport), ready-mixed to the house being built to a height of 20 m and a distance of 40 m. manage the installation of two people, but its performance defies the imagination - 1600 - 4000 l / h!
