Abstract

Supersulphated cement with 5%--10% of clinker, 15% of gypsum, 75-80% of slag was prepared, sulfate attack on mortars blended with ordinary portland cement and supersulphated cement was examined according to ASTM C1012 and the Chinese nation standard GB2420. It is shown that supersulphated cement exhibits excellent durability in sulfate attack environment, the 15-week expansion (ASTM C1012) decreased to less than 0.06%, 3-month corrosion coefficient (GB2420) of the SSC mortars immersed in Na2SO4 solution was 50% higher than that of the ordinary portland cement.
