Resourcesaving aerated concrete technology

Introduction. The need of the construction complex for resource conservation is briefly noted. It is shown that the demand of buildings for thermal energy depends on the stability of the properties of the enclosing structures of buildings under operating conditions. A scientific analysis of the ability of modern types of cellular concrete to absorb moisture has been performed. Aim. A scientific analysis of the ability of modern types of cellular concrete to absorb moisture has been performed. The most important reasons for autoclaved aerated concrete of D500 and below grades are listed, which ensure their increased tendency to moisture accumulation under operating conditions and form negative consequences for housing users. Materials and methods. The features of single-stage aerated concrete technology that control the degree of closure of their gas pores are described. Results. The results of experimental studies reflecting the effect of the length of polypropylene fiber on the rate of phase transition of aerated concrete mixtures from a viscous state to an elastic one and the ability of hardened aerated concrete to absorb vaporous moisture are presented. Conclusions. It has been established that only a single stage technology allows for the production of dispersed reinforced aerated concrete mixtures in turbulent mixers, which have a permeability comparable to that of brickwork.
