Fineness is related to the rate of hydration of cement. Better the hydration process occurs, we can have better performing concrete. Since the fineness increases the rate of hydration, it leads to an increase in the strength gain rate. Increase in the fineness improves the workability of concrete and also increases the setting time of the concrete.

The proportion of cement size greater than 90 microns is considered as fineness cement. In other words, the fineness of the cement is the particle size of cement. The maximum residue after the sieving in standard sieve should be limited to 10% by weight for OPC, and 5% by weight for rapid hardening cement.
