METHOD OF PREPARING FOAM CONCRETE MIX

摘要

FIELD: building materials industry, more particularly preparation of porous cellular concrete products. SUBSTANCE: method comprises mixing cement paste and individually prepared foam. Cement paste is prepared from cement slurry at water to cement ratio from 3:1 to 7:1 in two stages. In first stage, sedimentation ally unstable solid phase is recovered; and in second stage, the resulting slurry is kept till liquid phase is separated from cement paste. EFFECT: reduced average density, higher construction quality coefficient and accelerated solidification of foam concrete products. 1 tbl
