the cement. The fineness of cement effects the rate of hydration and, therefore, the rate of gain of strength and the rate of heat evolution. The Finer cement provides a greater surface area for the hydration process and faster strength development. But increase in fineness of the cement also increases the drying shrinkage of the concrete.
