FIELD: construction.
SUBSTANCE: composition is prepared on the basis of a glass powder, a binder, a gasifier and an aqueous solution of sodium silicate. The gasifier is represented by carbon or water-soluble organic compounds: glycerine, saccharose, glucose or their mixture. The binder is represented by organic acids - acetic acid or natural or synthetic amorphous silicates or alumosilicates: aerosil, amorphous silicon oxide, zeolites, diatomite, Tripoli powder, brick clay. The produced paste is poured into a mould with a relief bottom surface. Heating is carried out to harden the composition to produce strong raw stocks, which are then extracted from the mould and exposed to thermal treatment and burning.
EFFECT: reduced defective share in production of foam glass due to elimination of material crushing in process of cooling.
