Taking high sulfate resistant cement as the research object, the paper studied the effect of bentonite, HPMC, LA and super-plasticizer on the performance of slurry,and the formula of funnel viscosity, bleeding rate and concretion body strength to meet the design requirement of high sulfate cement stable, the result showed that the adjunction bentonite and HPMC can reduce bleeding rate, increase the viscosity of slurry, adding super-plasticizer while reduces the funnel viscosity of slurry, but increases the bleeding rate. The adjunction LA new dispersant can reduce the funnel viscosity of slurry, and can not increase the bleeding rate.
