FIELD: chemistry.
SUBSTANCE: invention relates to production of artificial coarse porous aggregates used in foamed concrete. In the method of treating porous aggregate, involving preparation and fractionation of aggregate grains, the grains are saturated with a foaming agent, followed by drying.
EFFECT: obtaining porous aggregate which enables uniform foaming in a concrete mixture.
