  • Ettringite Formation and the Performance of Concrete

    gypsum becomes depleted. This was demonstrated by Lerch in 1945; he showed that gypsum additions to give cement SO 3 con-tents of up to 5.0% had no significant impact on expansion of mortar bars stored in a moist room. However, when inordinately high gypsum levels (up to 7.5% as SO 3) were added to clinker, excessive expansionsGypsum Cement industry news from Global Cement,Roughly speaking, cement production requires about 5% of gypsum. So a 1Mt/yr cement plant would require around 50,000t/yr of gypsum. The crucial question for cement producers in West Africa is where is this gypsum coming from. Given that the Global Cement Directory 2018 places cement production capacity at just under 100Mt/yr in

  • Why Is Gypsum Added to Cement? , Hunker

    The terms cement and concrete are used interchangeably, although cement is actually an ingredient of concrete. Gypsum is often added to cement and concrete to slow down the drying time. Cement dries quickly and retarding that process allows workers to pour the mixture into the various forms or Cement Milling Understanding Cement,Cement milling and gypsum dehydration Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris 2CaSO 4H 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4 ).
