Claims (5)

1. Building material "Elstar" obtained by molding a homogeneous mixture of cement with crushed moistened wood and liquid glass, characterized in that during molding the mixture is subjected to direct current electrostabilization with periodic pole changes. 2. The building material according to claim 1, "Elstar", characterized in that the molded mass includes,%:
Shredded wood (mainly coniferous) - 65
Cement grade 400,500 - 21
Liquid glass - 3
Water - Else
and electrical stabilization is carried out at a temperature of not more than 40 ^o C for 45-60 minutes with a direct current of 10 kW per 1 m ³ with a periodic change of poles after 4-5 minutes.  3. A method of manufacturing products from the Elstar building material by molding building blocks, including the preparation of crushed wood with sieving it in fractions, moistening the wood, forcing it to mix with cement and water glass, loading the mass into molds with its compaction, holding moldable blocks in molds and removing blocks from the molds, characterized in that the chopped wood is pre-moistened by sprinkling and forcibly mixed with cement and liquid glass until a homogeneous mass is obtained, prepared with the mixture is discharged through the outlet of the mixer into special metal molds, the side walls of which have dielectric inserts, and the lid and tray are made of stainless steel, the mixture is sealed to the required density using a press, in particular hydraulic, the mold is fed to the electrostabilization station, to the electrodes, which are used as a lid and a pallet, they connect a direct current with a periodic pole change, after electrolysis, the blocks are kept in metal molds for 4-5 hours to acquire formwork strength, with Using the press, the product, along with the liners and the pallet, is pressed onto special substrates and kept for 4-5 days at room temperature to acquire transport strength.  4. A method of manufacturing products from building material "Elstar" according to paragraphs. 1 and 3, characterized in that the products are made in the form of wall panels 250x600x1200 mm, blocks 250x250x1000 mm, 250x400x600 mm and partitions 100x250x1000 mm.  5 A method of manufacturing products from building material "Elstar" according to paragraphs. 1 1 and 3, characterized in that the building structure from the outside is provided with thermal insulation in the form of boards 80x600x1200 mm of fibrous material and a half-sized brick, which are attached to the building structure with nails with end rods.
