What is the purpose of adding gypsum in cement?

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”.

Cement: Materials and manufacturing process

• About 20% of gypsum goes towards cement production. And Cement Substitutes . A number of by-products from other industries can be blended with Portland Cement (CEM I) which can improve performance but also increase the recycled content and reduce the ECO2 content of the concrete. The use of these secondary materials utilises material which might otherwise be
