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” 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 process involved in hydration of cement is that, when the water is added into cementRole of Gypsum in Cement and its Effects The This chapter highlights the usage of gypsum, which has long been recognized as an important and essential component of Portland cement Gypsum was first used with Portland cement to retard the rate of setting sufficiently to permit the proper placing of mortar and concreteGypsum in Cement ScienceDirect
