Use of industrial waste in the production of non-autoclaved foam concrete

Abstract

The paper presents the relevance of the use of industrial waste, in particular, fuel ash generated by thermal power plants. The application of fly ash in the production of non-autoclaved cellular concrete, namely foam concrete is substantiated. The mechanism of structural formation of foamed concrete with the use of silica component is given. The dependence of the strength of foam concrete with density D600 on the ratio of silicious component to binder by mass is determined, and the macrostructure of the developed compositions is shown. It is concluded that it is reasonable to use TPP fly ash as a silica component for foamed concrete mixtures.
