FIELD: production of building materials.
SUBSTANCE: invention can be used for the production of structural thermal insulating concrete for residential and civil construction. The raw mixture for the manufacture of composite building material contains, wt.%: a suspension of insoluble residue of tripolite from the Sukholozhskoe deposit of the Sverdlovsk region in a solution of liquid glass 52-60, sodium silicofluoride 7-9, microsilica produced by Chelyabinsk Electrometallurgical Plant, JSC 7-10, lignin of Tavdinsky Pulp and Paper Mill of the Sverdlovsk region 26-29. In this case, the suspension is obtained by mixing tripolite from the above deposit, ground to a specific surface of 2000 m2/g, with a 40% solution of caustic soda and water at their weight ratio of 1: 1.34: 3.1, respectively, held at 95°C for 4 hours and cooled.
EFFECT: increasing the strength of building materials in compression and bending, recycling industrial waste.
