It is about 25-50% (normally about 40 percent) of cement. It renders the clinker easier to grind, increases resistance to freezing and thawing, hydrates rapidly generating high heat and develops early hardness and strength. However, raising of C3S content beyond the specified limits increases the heat of hydration and solubility of cement in water.
