FIELD: construction.
SUBSTANCE: method of preparing limestone construction rubble includes impregnation of a limestone rubble in aqueous lignosulfonate solution at a temperature of 50-60°C in the ratio of lignosulfonates: water 1:(8-12), exposure in solution at atmospheric pressure with subsequent drying to constant weight, impregnation of rubble in aqueous lignosulfonate solution is made simultaneously with degassing in vacuum installation where residual pressure 2000 Pa for 60 min is created and maintained, then the pressure is adjusted to atmospheric pressure at which the sample is held for 30 min, and the sample is dried to constant weight at a temperature of 100-130°C.
EFFECT: increased water resistance of limestone crushed stone.
