FIELD: chemistry.
SUBSTANCE: invention relates to construction materials, specifically to mixtures for making clinker which can be used in making cement. The raw mixture making clinker contains the following in wt %: dust from electric filters for cleaning waste gas from aluminium electrolysis - 5-10, sludge from cleaning waste gases from aluminium electrolysis - 5-10, carbon mixture of graphite, coke, coal, formed when repairing electrolysis cells for producing aluminium - 10-20, limestone and clay - the rest.
EFFECT: recycling wastes from aluminium industry, averaging chemical and mineral composition of clinker, increased strength of cement made from the clinker.
