CRUDE MIXTURE FOR MAKING AEROCRETE WITH HIGH STRENGTH CHARACTERISTICS

摘要

FIELD: chemistry. ^ SUBSTANCE: invention pertains to production of aerated concrete without autoclave hardening and can be used for making construction materials. The crude mixture for making aerocrete consists of the following components with the given percentage mass ratios: 27.5-29.1% portland cement; 34.9-38.5% flue-ash; 1.67-1.77% gypsum building plaster; 0.13-0.145% aluminium powder; 0.13-0.145% Taiga detergent; 1.8-1.9% microsilica; 0.110-0.116% calcium chloride; water constitutes the remaining percentage. ^ EFFECT: increased strength of the material; increased quality coefficient; reduced air shrinkage. ^ 2 tbl, 1 ex
