The coincidence of temperature intervals of decarbonization of CaCO3 and dehydration of layered aluminosilicate muscovite and biotite contributes to the occurrence of solid-phase reactions at relatively low temperatures of 900-1250 °C, the appearance of aluminates of calcium and β-modifications 2СаО·SiO2. The product roasting at temperatures 1200 °С in the mixture with quartz sand has a high activity under hydrothermal conditions, the compressive strength after six-hours of hardening is of 45,3 MPa.
