FIELD: building materials. SUBSTANCE: wall material comprises the following components, wt.-%: granulated blast furnace slag as a binding agent, 30-36; wood sawdust, 18-24; water glass, 25-30; soda ash, 10-16; unslaked lime, 0.03-0.035; water, the balance. Invention provides the enhancement of strength at insignificant elevation of density value. Proposed wall material can be used in making structural-heat-insulating material based on organic filling agents and mineral binding agents. EFFECT: improved and valuable properties of material. 3 ex
