FIELD: chemistry.
SUBSTANCE: invention relates to production of building material and can be applied in production of artificial porous fillers for light concretes and heat-insulating fillings. Raw material mixture for obtaining porous filler includes silica-containing rock and gas-former, as gas-former, it contains mixture of aluminium oxide and silicon carbide with the following component ratio, wt %: silica-containing rock - 95.0-96.0, aluminium oxide 3.0-4.9, silicon carbide 0.1-1.0.
EFFECT: increase of porous filler strength by reduction of filler agglomeration with reduction of its water-absorption and heat-conduction.
