Abstract
From the point of view of comprehensive utilization of yellow gypsum,the preparation of high-performance concrete was discussed by using different ratio of yellow gypsum,cement and sand.The results showed that the compressive and flexural strength of the cement mortar which was added to 0-10％ of yellow gypsum could meet the standard requirement of P.(0)42.5 cement.When the yellow gypsum particle size is 0.074mm more than 98％ after drying and grinding,the C30 of concrete can be prepared by using the mixture of cement,yellow gypsum and FAC-1 as cementitious materials,the ratio of which is 0～30％ of yellow gypsum,100～70％ of cement and 1.0～1.8％ of FAC-1.The impermeability of the concrete meets the requirement of P12.关键词
