Sulphate Resistant Cement

Sulphate Resistant Cement Sulphate Resisting Cement is a type of Portland Cement in which the amount of tricalcium aluminate (C3A) is restricted to lower than 5% and (2C 3A +C4AF) lower than 25%, which reduces the formation of sulphate salts. The reduction of sulphate salts lowers the possibility of sulphate attack on the concrete. In this article we study about the composition, properties, characteristics, uses, advantages and disadvantages of sulphate resisting cement. Composition of Sulphate Resisting Cement Due to very low range of tricalcium aluminate in sulphate resisting cement, a very small quantity of calcium aluminate is formed on hydration. The formation of calcium sulpho- aluminates which formed due to reaction of calcium sulpho-aluminates which formed due to reaction of calcium sulphoaluminate and sulphate salts is considerably reduced with use of sulphate resisting cement. The sulphate aluminates are highly expansive in nature and cause maximum dam
