Dec 01, 2012· Grinding. The lumps of clinker are ground up with calcium sulfate dihydrate (CaSO 4· 2H 2 O) or gypsum or active anhydrite to control the rate of hardening or the setting time (gypsum is also used to make Plaster of Paris, a commonly used rendering plaster). Usually about 2–10% of the groundup Portland cement is gypsum.
