Article Preview

In this paper, a concrete sulfate corrosion-resistance admixture is developed with anhydrite (CaSO4), super fine slag powder (P800) and anhydrous calcium sulfo-aluminate (C-S-A). It is optimized by means of systematical research on specific surface area, setting time, expansion ratio, compressive strength ratio, corrosion resistance coefficient and expansion coefficient of 20 mixes, which are designed based on the hydration mechanism and performance requirements according to JC/T1011-2006. This new type sulfate corrosion resistance admixture has good performance and completely satisfies the requirements of industry standard JC/T 1011-2006 regarding “Sulfate Corrosion-Resistance Admixture for Concrete”, and has declared Chinese national invention patent (201010256189.2).
