Method of production of cellular concrete

摘要

Cellular concrete is produced using, as filler, the sandy fraction of 80-90% SiO2 content which is a waste material from the combustion of brown coal and, as binding agent lime and cement. These raw materials are dry ground and mixed with water having a temperature of about 50 DEG C. and with a pore-producing agent. The thus obtained mixture is poured out into forms.
