Activation of fly ash/cement systems using calcium sulfate ...Anhydrite, another form of calcium sulfate, has not been used for this purpose. This paper presents an exploratory study on the effectiveness of anhydrite in activating fly ash cement systems. Anhydrite (10%) was added into cement mortars with up to 55% fly ash replacement.
Effect of Anhydrite on CementBased SelfLeveling Mortar ...In this paper, the effect of anhydrite on the cementbased selfleveling mortar performance was studied. The construction operation of mortar and its mechanical property testing were based on the standard JC/T . The results showed that the anhydrite played a significant role on the performance of compressive strength and flexural strength.
