  • Characteristics of cement that affect compressive strength

    The compressive strength of cement is principally affected by the relative content of lime CaO and the fineness More lime in the composition of portland cement means more of the C 3 S phase which provides higher early strength at a given fineness compared to the C 2 S phase Also greater fineness for the same lime content indicates higher
