The results of research of the multi-walled carbon nanotubes dispersion influence on improvement of the thermal insulation autoclaved aerated concrete structure and physicomechanical characteristics are presented in this article. The studies found that the carbon nanotubes using contributes to obtaining the optimum viscoplastic properties of aerated concrete massive and stabilization of pore formation with the structuring of a dense uniform hexagonal pore structure. The modified thermal insulation autoclaved aerated concrete composition and structure analysis showed that multi-walled carbon nanotubes act as centers of calcium hydrosilicates directional crystallation, which contributes to the enhancement of aerated concrete physico-mechanical properties. As a result, samples were obtained with strength class B0,5, with an average density grade D200 and thermal conductivity coefficient 0,046 W/m.о С.
