Abstract
Calcium hydrosulfasaluminates (GSAK) is a component of cement. They are slowly formed together with the forming of the structure of cement in water solution at measurable temperatures (0-25 °C) during about 4-6 months. Slow rate of crystallization of GSAK wasn`t allowed to treat them as self-autonomy objects for use in various technological applications. The possibility of formation of GSAK (4CaO×Al2O3×mSO3×nH2O) is proved in an environment of saturated electrolytes – aluminates solutions of alumina production. They crystallize in a short time about 1-2 hours and retain their stability in long time about 24-36 hours. This allowed for us to identify ways of their industrial use.
