Gypsum Is Essential and Necessary to Cement Fote Machinery

Jul 26, 2021  Without gypsum, the cement will set immediately and release heat after mixing with water, and there will be no time to pour the concrete. The main reason is that C3A in the clinker can quickly dissolve in water, forming a hydrated calcium aluminate- a coagulant that can destroy the properties of cement.
