The report shows the possibility of expanding the raw material base for cement clinker production while reducing the consumption of carbonate and clayey natural materials. The research methodology combines the use of computer-based analysis of raw material compositions with chemical, X-ray phase analysis, and technological testing according to current standards. The composition of raw material mixtures is analyzed based on the chalk-waste from papkru production-screening from perlite extraction system with varying the quantitative ratio of components at given characteristics of the firing product. The compositions of mixtures with the introduction of 16–36 wt.% of osmium were determined. The features of the phase formation of cement clinker in the range of maximum firing temperatures of 1200–1400 °C and the properties of cement were shown. The possibility of regulating the setting time by varying the content of osmium and the quantitative ratio of the components of the initial raw material mixture has been determined.
