What is the purpose of adding gypsum in cement?

Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process.

Cement Milling Understanding Cement

Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. For a quick introduction to VRMs see, for example, this advertisement on Youtube for an FL Smidth VRM. 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).

Process Ball Mill Heating and Cooling Clinker Cement

3C.5 Flash Set and False Set Gypsum and anhydrite calcium sulfate is added to cement chiefly as a set retarders. Calcium sulfate reacts with the quick setting component of cement C3A. During the milling process, some or all of the gypsum will dehydrate to hemihydrate.
