FIELD: construction industry; production of wall ceramic products. ^ SUBSTANCE: the invention is pertaining to the field of construction industry, in particular, to production raw materials mixture for production of wall ceramic products. The technical result of the invention is an increased frost resistance of the products at reduction of a shrinkage and temperatures of the material roasting. The raw materials mixture contains (in mass %): microsilica of production of crystalline silicon - 30.43-31.82, a fly ash from incineration of brown coals - 56.52-59.09 and a prorash from bucking of the spent carbon lining of electrolytic baths - 9.09-13.04. ^ EFFECT: the invention ensures an increase of frost resistance of the wall ceramic products at reduction of their shrinkage and the material roasting temperatures. ^ 1 ex, 2 tbl |
