The Power of Gypsum Indian Cement Review
网页2022年7月18日Gypsum is used in Portland cement to regulate sets and is added to clinker at a level of about 5 per cent. When water is added to cement, it starts reacting with the C3A and hardens. The time taken in this process is very less, which doesn’t allow time for transporting, mixing and placing.
