The mixture then sent to final grinding process. For ordinary Portland cement it remains between 3 to 4% and in case of Quick setting cement it can be reduced up to 2.5%. Role of Gypsum in Cement The main purpose of adding gypsum in the cement is to slow down the hydration process of cement once it is mixed with water.

The role of gypsum in cement

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.
