  • What Are The Roles Of Gypsum In Cement Production

    Dec 15 2020 The delayed coagulation on cement clinker produced by mixing a moderate amount of gypsum is generally thought that when cement is hydrated gypsum reacts quickly with C 3 A and Ca HO 2 to form water-insoluble calcium sulfoaluminate hydrates that is ettringite C 3 A3CaSO 4 Ca HO 2 which can form an coating layer on the surface of C 3 A particles prevent further hydration of

  • What Is The Purpose Of Adding Gypsum In Cement Civil

    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. If not added the cement will set immediately after mixing of water leaving no time for concrete placing.
