- Аннотация: The article presents the results of the study of the hydration processes of sulfated minerals and mixtures based on them. It has been established that ferrous calcium ettriteite formed upon calcium sulfoferrite hydration is more stable at elevated temperature in comparison with its cassic ettringite. In the products of hydration of mixtures of alite and sulfated phases, at elevated temperature and pressure, ferrous iron garnetts are formed, the composition of which depends on the amount of silica in the mixture. The hydrogranates are crystallizing in the form of octahedra and rhombic dodecahedron, the pores them fills tobermorite, crystals of ferrite ettringite, which creates a dense and non-shrinkable structure of cement stone.
