    Gypsum is a sedimentary rock having a composition of calcium sulfate (Ca SO 4. 2 H 2 O). It is added for imparting a retarding effect in the setting of cement. (Without gypsum the cement would set, within minutes after adding water into it. It will be, therefore, very difficult to work with such a type of cement

    Gypsum and Cement Production - two elementary building materials. Cement is used everywhere imaginable: for example, as a binder for concrete, mortar or screed, making it one of the world's most important building materials. If we just consider concrete, most of our infrastructure and architecture simply wouldn't be conceivable without it. And gypsum plays a similarly important role inside buildings
