Gypsum Addition - an overview | ScienceDirect Topics A larger fraction of SO 3 is added to cement in the form of calcium sulfate, either as gypsum, CaSO 4 2H 2 O, or anhydrite, CaSO 4. During cement grinding, a fraction of the gypsum may be decomposed to hemihydrate CaSO 4 ½H 2 O. The main role of calcium sulfate is to control cement setting, although strength may also be affected.

Cement Milling As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 4.2H 2 O). Natural anhydrite (CaSO 4) may also be added. Cooling is necessary to limit the temperature rise of the cement. This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill.
