Nonferrous waste aerated concrete

This article presents studies of the technological process for producing curing monolithic aerated concrete from industrial slag sands. The purpose of this work is to develop and optimize the composition of lightweight concrete using gypsum building plaster as a binder. For the construction of low-r...
