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 ...
