FIELD: chemistry.
SUBSTANCE: invention relates to industry of construction materials. Raw material mixture for manufacturing ceramic construction products of various purposes includes ash microsphere, argillic raw material and ground glass with density 2500 kg/m3. Ratio of components in mixture is the following, wt %: ash microsphere - 42-60; argillic raw material - 13-41; ground glass - 10-43. Ratio of ash microsphere to mixture of argillic raw material and ground glass constitutes 1.5-0.724.
EFFECT: increase of specific strength of material with preservation of its heatproof characteristics.
