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.

The influence of cement, amount of watersolid WS ratio, water-reducing agent, citric acid content and the hydration age on the gypsum blocks was investigated. The results showed that the optimum WS ratio, cement content and water-reducing agent are 0.9, 10 and 2 wt for the calcined gypsum from titanium gypsum, respectively.
As for applications of solidified forms of these materials in our daily lives, cement is used as mortar and concrete, and gypsum calcined gypsum is used as a gypsum board. Both are indispensable materials for building construction, but the process of their production and the nature of the products generated are quite different.
In Rajasthan, gypsum mining is controlled by FCI Aravali Gypsum amp Minerals India Ltd and Rajasthan State Mines amp Minerals Limited. Rajasthan accounts for about 99 of the total production of gypsum in the country, but as it is in North-West India, transportation costs are prohibitive for many cement producers located elsewhere in the country.
Gypsum powder is also added to cement and paints used in building construction and finishing. In cement and concrete mixes, gypsum helps to increase the time it takes for concrete and cement to dry and harden, resulting in a more stable structure. In paint, gypsum powder is used a filler to adhere to the pigments and improve the paints texture.

Sep 27, 2018 Gypsum prevents Flash Setting of cement during manufacturing. It retards the setting time of cement. Allows a longer working time for mixing, transporting and placing. When water is mixed to cement Aluminates and sulfates get react and evolve some heat but gypsum acts as coolant and brings down the heat of hydration.
