  • Research on red mud-limestone modified

    After drying, the desulfurized gypsum has strong water absorption, and it is easy to generate H 2 S during the high-temperature calcination process, which causes environmental pollution,. When the solid–liquid ratio of the red mud-limestone process reaches 1:10, the calcium sulfate in the gypsum mostly exists in the form of CaSO 4 ·2H 2 O.Optimization of the activation Cement Lime Gypsum,In addition, another work studied the reactivity of a thermal anhydrite obtained by calcination of FGD gypsum [16]. Values of the degree of hydration around 50% were obtained with additions of K 2 SO 4 between 0.5% and 3.3%, without the addition of lime. The authors proposed that the hydration mechanisms are associated with the formation and
