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.

Gypsum plays an important role in controlling the rate of hardening of the cement. During cement manufacturing process upon cooling of clinker a small amount of gypsum is added during the final grinding process. Gypsum controls the setting of the cement and if not added the cement will set immediately leaving no time for concrete placing.

Gypsum is an indispensable element which regulates the setting time in cement and in the absence of it the clinker condenses instantly after coming in contact with water. This happens because of the presence of CA3 in the cement clinker which after dissolving in water creates a coagulating element.
