[Solved] Statement (I): Finer grinding of cement results in
The early development of the strength of cement is directly proportional to its rate of hydration. As such, a higher rate of hydration means more and more cement gel is forming in very less time. Hence, the rate of development strength will be higher. This hydration reaction occurs on the surface of cement particles (it is a surface phenomenon
