Results of preparing Portland cement by low-energy technology using technogenic raw materials are presented. Coal mining waste and tephritobasalt in a ratio of 1:1 are used as the clay component, and granulated lead slags are used instead of scarce pyrite cinder. Correlation of the influence of charge compositions, saturation coefficient, silicate and alumina moduli, firing regimes with chemical and mineral composition and clinker and cement quality are established. Composition of the raw material mixtures is calculated according to a ROCS program, and the free CaO content in clinker composition is determined. Experimental cement strength is tested after hardening for 7 and 28 days. Its physicomechanical characteristics and structure are studied.
