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 is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including
For the manufacture of drywall and plaster material the mined gypsum is used as the raw material. Synthetic gypsum is used in more amount for manufacture. The wet limestone which is a combination of calcium and water, when combined with sulfate forming calcium sulfate or gypsum is called as a chemical gypsum or synthetic gypsum.
