Non-autoclaved aerated concrete properties as a macroporous building material, depend on the macrostructure quality strongly. The macrostructure formation occurs at the stage of expansion and hardening of given composition mortar mix. The aerated concrete large-pore cellular structure formation mechanism, which involves two simultaneous processes: the expansion of mortar mix and hardening of the interporous space are presented in this article. Herewith, as the researchers note, when the structure formation mode deviate from the optimal product quality decreases up to a critical value. The low quality products formation (spoilage) can be due to several reasons, which are outlined in this work. The authors systematized prescription and technological factors influencing the material macrostructure formation. It was noted, at present the AC structure formation management is mainly provided by the adjustment of the initial composition; technological parameters, due to the insufficient study of their influence on the array expansion and hardening processes in modern technology given less attention. In conclusion, the study authors noted that the fast management of the structure formation processes will improve the products quality and reduce the spoilage number.
