    Degree of fineness for cement is the measure of size of grain in it, there are three methods of testing of fineness of cement: 1) Sieve methods – using 90 micron sieve, 2) Air permeability methods – Nurse and Blaines method and 3) Sedimentation method – Wanger turbidimeter method. Sieve method measure grain size where as their permeability and sedimentation method measure surface area.
