Cement is produced from a chemical combination of calcium, silicon, aluminum, iron and small amounts of other ingredients that are carefully measured to get the right result. Often gypsum is added during the final grinding process since it helps regulate how long the concrete takes to set.
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 added to control the "setting of cement".

Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates.In the form of γ-anhydrite (the anhydrous form), it is used as a desiccant.One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum.It has many uses in industry. All forms are white solids that are poorly soluble in water.
After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects.

Gypsum is a mineral and is hydrated calcium sulphate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement, so its is generally termed as retarding agent of cement. It is mainly used for regulating the setting time of cement and is an indispensable component.
Gypsum and Cement Production - two elementary building materials Cement is used everywhere imaginable: for example, as a binder for concrete, mortar or screed, making it one of the world's most important building materials. If we just consider concrete, most of our infrastructure and architecture simply wouldn't be conceivable without it.
India's cement production capacity stood at around 502 million tonnes per year (mtpa) in 2018 and is expected to reach 550 mtpa by 2025. Typically, manufacturing cement uses 2 to 4 per cent gypsum per tonne of cement. Thus the country requires importing substantial gypsum to cater to the requirements of cement industry.
FGD issues affect, directly or indirectly, coal, gypsum, lime, limestone, and soda ash industries. Increased commercial use of FGD products represents an economic opportunity for high-sulfur coal producers and the sorbent industry. Synthetic gypsum competes directly with natural gypsum as raw material for wallboard and cement manufacture.
