Research on Sulfate Attack Resistance of Concrete with Sulfate Corrosion-Resistance Admixture

Abstract:

A concrete sulfate corrosion-resistance admixture is developed with anhydrous calcium sulfo aluminate (C-S-A), super fine slag powder (P800) and anhydrite (CaSO₄) in this paper. Scope of prescription is optimized according to performance requirements of JC/T1011-2006. This sulfate corrosion-resistance admixture has declared Chinese national invention patent (201010256189.2)[1]. Corrosion resistance coefficient is tested after sulfate corrosion-resistance admixture is adjoined into fly ash concrete. The results reveal that sulfate resistance of the concrete is obviously improved by addition of sulfate corrosion-resistance admixture, and the its anti sulfate erosion grade is KS150.
