FIELD: chemistry.
SUBSTANCE: invention relates to production porous aggregates for concrete. The mixture for producing porous aggregate contains the following, wt %: montmorillonite clay 88.7-92.2, dolomite ground to specific surface area of 2500-3000 cm2/g 1.0-1.5, natural vermiculite ground to specific surface area of 2500-3000 cm2/g 6.0-10.0, carboxymethyl cellulose 0.1-0.2, liquid potassium glass 0.1-0.2.
EFFECT: high strength of porous aggregate made from the mixture.
