Sulphate Resisting Cement ManufacturingSulphate
CH produced in the hydration process of C3S is another factor leading to corrosion. Therefore appropriately reducing the content of C3S and correspondingly increasing C2S which has better performance is also an effective measure to improve the corrosion resistance of sulfate resistant cement.

It was found that the composition of the cement did have an effect but not as great as did differences in the curing regime. The concretes made with the higher C3S/C2S ratio cements had properties which were as good as or in some respects superior to those made with cements with a low C3S/C2S ratio.

· It has been proved earlier that the weight of water required by C3S accounts for 24 of the weight of cement while the weight of water required by C2S accounts for 21 of cement. It has also been estimated that the chemical reaction with the Portland cement compound requires on average 23 of the cement weight of water.
