FIELD: chemistry.
SUBSTANCE: invention relates to the construction industry and can be used to make autoclave-cured heat insulation, structural-heat insulation and structural articles. The crude mixture for making autoclave-cured cellular articles contains, wt %: high-calcium lump quicklime 5-12, portland cement 7-14, ground quartz sand 38-51, aluminium paste 0.03-0.12, binder consisting of pre-slaked lime with an additive of ground gypsum dihydrate in amount of 0.05-0.25% (with respect to the hemihydrate) 15-25%, water (more than 100% dry components) in an amount which corresponds to the water/solid (W/S) ratio of 0.5-0.6.
EFFECT: high quality of structural materials with a cellular structure, low water consumption in the crude mixture, shorter time for ageing the raw material before autoclave treatment.
