  • Gypsum Is Essential and Necessary to Cement | Fote Machinery

    · As the reaction between water and cement continues, the plasticity of the cement paste is lostAs a retarder, gypsum can prevent cement material from hardening so fast, and effectively control the setting time The retarding mechanism of gypsum is that when cement is hydrated, gypsum reacts quickly with C3A to form calcium sulfoaluminate hydrate or socalled ettringite This ettringite· In China, more and more cement factories are trying to use the chemical gypsums as a cement retarder instead of natural gypsum (NG) Cement is the most massive manmade material, 004–008 ton of gypsum is needed to produce 1 ton of cement, and there were around 15 billion tons of cement produced in China in 2008 If PG had been substituted for the NG as cement retarder, 75Utilization of solidified phosphogypsum as Portland cement· Gypsum Mill For Cement Retarder dewaeleet cement gypsum crusher Gypsum is also called plaster The gypsum mine is the main raw material to produce gypsum binder and gypsum building products and the retarder of portland cement After calcining under 600~800C and adding little catalyst ( such as lime ) we can levigate the whole mixture and get anhydrite binder which is alsogypsum portland cement retarder joseracielakpl
