Super Sulphated Cement: (IS: 6909)

Super Sulphated cement is made from well granulated blast furnace slag (80- 85%), calcium sulphate(10- 15%), and Portland cement (1 – 2 %) and is ground finger than the Portland cement. One of its most important properties is its low total heat of hydration. It is, therefore very suitable for construction of dams and mass concreting work. Concrete made from Super sulphated cement may expand if cured in water, and may shrink if the concrete is cured in air. Another big advantage of super sulphated cement is its comparatively high resistance to chemical attack.
