  • Role of Gypsum in Cement and its Effects The Constructor

    Sep 27, 2018· 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 cement, it starts reacting with the C3A and hardens.What is the purpose of adding gypsum in cement? Civil,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.
