The paper provides research results on obtaining a compositional CLWD with the use of ashes from the Novo-Irkutsk Thermal Power Station and magnesites of the Savinsk deposit of the Irkutsk area. The aim of the research is to develop an effective ecological technology for producing high-quality cements. As a result of the research, the technological and physical-mechanical properties of the cement paste and cement stone were determined. The cement ND changes depending on the composition (12 to 19%), while the cement stone’s strength varies from 49.5 MPa to 77.7 MPa. The CLWD strength (of different grades according to GOST 310.4) is estimated in 1 day, 28 days, and after steaming. A comparison with ordinary Portland cement was made. It is established that the CLWD 50 (has 50% of fillers) is not inferior in its physico-mechanical properties to ordinary Portland cement. A regression analysis of the influence of a number of factors on the strength of CLWD at three time periods (1 day, 28 days, and after steaming) was carried out. The regression equation was also obtained.
