The results of research aimed at obtaining of the thermal insulation autoclaved aerated concrete with the required level of the structure strength are presented in this article. The studies found that joint introduction in aerated concrete mixture of the specialized blowing agent with monodispersed particles, polycarboxylate and multi-walled carbon nanotubes dispersions to obtaining the enhance of strength properties of the thermal insulation autoclaved aerated concrete and slight decrease in its density and thermal conductivity by filling cracks crystal- line blocks tumors ordered structure and redistribution of the volume of micropores and capillaries in aerated concrete structure. Optimization of autoclaved aerated concrete composi- tion was performed by complex criterion of its quality by means of «Decon-SM» software product.
