Calcium Sulphoaluminate Cement (CSA) 

SAC 42.5 is rapid-hardening sulphate aluminium cement. It is hydraulic binding material consisting essentially of anhydrous calcium sulphoaluminate and dicalcium silicate. Certain quantity of  gypsum and 0-10% limestone are blended with clinker during manufacture process.   SAC 42.5 shows the performance like high strength, rapid hardening, corrosion resistance, frost resistance, impermeability and carbonation resistance, which allows to be used in many application projects such as urgent repair and rapid construction, low temperature construction, and fast setting mortars such as self-leveling compound etc.   Product properties   Specific surface area (m2/kg) ≥ 350 Setting time (min) Initial ≥ 25 Final…
