required. In addition to gypsum will react with the tricalcium aluminate mineral (C 3 A) which is the compound mainly responsible for the early setting time of cement. The reaction of gypsum with (C 3 A) will retard the setting time of cement ( prolong the setting time) which
Up to 200708, the Indian cement industry met their gypsum requirement predominantly from natural gypsum sources in Rajasthan and the byproduct gypsum from industrial sources. However, such sources for gypsum peaked and stagnated and the incremental requirement was met by imports, mainly from Thailand and Iran.

mineral. Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco.

Of relevance to the cement industry, it will include limestone flux, quicklime, slaked lime, gypsum, anhydrite, clinkers of Portland, aluminous, slag, supersulfate and similar hydraulic cements, white Portland cement, Portland cement, aluminous cement, slag cement, refractory cements, additives for cement, cement based building materials and more.
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.
