Cement mill - Wikipedia

Heat generated in the grinding process causes gypsum (CaSO 4.2H 2 O) to lose water, forming bassanite (CaSO 4.0.2-0.7H 2 O) or γ-anhydrite (CaSO 4.~0.05H 2 O). The latter minerals are rapidly soluble, and about 2% of these in cement is needed to control tricalcium aluminate hydration.

What are the Roles of Gypsum in Cement Production - Oreworld

Gypsum makes up only about 3% or less of cement, but it plays an important role in cement. The application of gypsum in cement is mainly to delay the setting time of cement, which is beneficial to the mixing, transportation and construction of concrete. If there is no gypsum in the cement, the concrete will set quickly in the mixing process, resulting in the failure of stirring and construction. The reason why fast setting occurs in the cement without gypsum after mixing with water is mainly
