Invention relates to the field of building materials industry, namely to methods for manufacturing of products from autoclaved aerated concrete with higher mechanical and thermal resistance. Invention also relates to compositions of autoclaved aerated concrete. The objective of the invention is to enhance the mechanical and thermal resistance of products. In the method for manufacturing of products from autoclaved aerated concrete, which involves mixing of forming mix from binding material, sand, aluminium powder, pozzolanic additive, reinforcing fiber and water, pouring of obtained mix into moulds, maturing, cutting into products and their autoclave hardening, the said reinforcing fiber is from basalt wool. Before mixing of forming mix, the said reinforcing fiber from basalt wool is obtained by crushing basalt wool, then by fibering and dispersing crushed basalt wool. In capacity of basalt wool, the waste of basalt wool production is used. In the composition of autoclaved aerated concrete, which is comprised of the binding material consisting of cement and lime, as well as the sand, aluminium powder, pozzolanic additive, reinforcing fiber and water, the said reinforcing fiber is basalt wool fiber, in the following proportions of components in %:
