Process parameters of production of non-autoclaved aerated concrete on the basis of complex use of ash and gypsum-containing wastes

Abstract

Aerated concretes belong to the most effective materials for fencing structures of buildings of different purpose. They are characterized by their quite high strength and freeze resistance though they have comparatively low average density. More and more perspectives for their further production and appliance in construction is created by their high technical and economical indications of production and appliance of aerated concrete products, fire safety, as well as comfortable living conditions inside houses with aerated concrete walls because of their high air and vapor transmission. Aerated concrete of non-autoclaved hardening on physical and mechanical properties, close to properties of autoclaved aerated concrete (D<600, M>35, F>50), is intended to be produced by mechano-chemical activation of raw components, optimization of quality of aerated concrete macroporous structure and complex use of production as well as fuel and power complex wastes.
