ABSTRACT
The aim of this paper is to determine the methods of cement mixtures water yield decreasing and sedimentation resistance improving. For that purpose we have run experimental studies to learn the degree of aeration and hydroxyethyl cellulose influence on water-containing ability of the cement mixtures. We have found that the addition of solid fillers in the gas-liquid cement mixtures composition prevents the liquid flow out from their cellular structure. There is information on the effect of cement mixture mechanical activation on the filtrate loss value. We have solved the problem of obtaining a stable cement composition by using various methods to reduce water yield.
