Penoblock is a building material made of cement, sand and water with the addition of a foaming agent that gives it a porous structure. By the form and method of using foam blocks, they are similar to slag block, but at the same time made of environmentally friendly material and, due to their porosity, have much better heat – and soundproofing properties. In its density, the foam block is divided into stamps from 400 to 1200. Guided by this marking system, it should be borne in mind that a denser foam block of the brand 700-1200 is used to form the foundation and the main load-bearing walls. For the construction of internal walls – foam block of the brand 600-700, and for thermal insulation – already a very easy version of the 400th brand.
The principles of the formation of the foundation and the building itself do not actually differ from classical representations. To begin with, the first row of foam block is laid out on the sand pillow, and all angles and sizes are measured so that they correspond to design values. Foam blocks are laid on a cement pillow. Further, using the same cement mortar, the foundation is built to the desired level. Between each two or three rows, waist reinforcement from a grid or reinforcement is performed.
After erecting the foundation, waterproofing is carried out to prevent moisture from the lower levels, thereby preventing the saturation of foam block with moisture and its destruction. It is also advisable to put the first few rows of walls over the foundation using cement, but when laying subsequent ones, you can use special adhesive compounds for foam blocks, which reduce the total specific weight of the structure and reduce the gaps between the blocks up to 2 mm, which will significantly reduce the thermal conductivity of the entire masonry. It is important that the blocks themselves are performed correctly and have no divorces in size. Throughout the construction of the walls, the masonry should be reinforced with a grid or reinforcement through several rows of foam block. For the formation of window openings, either reinforced concrete beams are used, or are independently poured using formwork and reinforcement. Having reached the level of ceilings, Armopias is installed. The floors can again be made both from the beam and using the floor slabs.
In general, the house, composed of foam block, comes out much cheaper in means, due to the lower costs of material and specialized equipment, because this material weighs little and easily lends itself to processing: it saws with a hacksaw, plugs and drilled.
