FIELD: chemistry.
SUBSTANCE: invention relates to production of construction materials and can be used in making ceramic articles for different purposes - clinker and acid-resistant bricks, ceramic floor tiles etc. The crude composition for making ceramic articles includes a mixture of hydromica-kaolinite and kaolinite-montmorillonite clay, a mixture of screenings from crushing granite chips, aluminium alloy etching wastes and technical lignosulphonate, in the following ratios, wt %: hydromica-kaolinite clay - 9.9-19.8; kaolinite-montmorillonite clay - 49.8-74.9; screenings from crushing granite chips, particle size 0.315-0.63 mm - 10-20; aluminium alloy etching wastes - 5-10; technical lignosulphonate - 0.2-0.4 (per dry substance).
EFFECT: higher compression strength and frost resistance of articles.
