Uses of Gypsum in Cement
During the final grinding process of the cement, gypsum is added. This should only be done once the clinker has cooled down during the cement manufacturing process. Gypsum also helps in controlling the rate at which the cement hardens. After the cement is mixed with water, the gypsum helps in preventing the setting of cement immediately.
