Fineness Test. The degree of fineness of cement is the measure of the mean size of the grains in it. There are three methods for testing fineness: the sieve method-using 90 micron (9 No.) sieve, the air permeability method- Nurse and Blains method and the sedimentation method- Wagner turbidimeter method. The last two methods measure the surface ...

Fineness of cement is the direct indication of its particle size. Generally, it is measured on a scale of 1-10. Lower the fineness of the cement / aggregate finer is the particle size. And finer the particle size, greater will be the surface area available for hydration of cement. Which will certainly mean there is increase in rate of hydration.
