Test Method for Fineness Fineness of Cement Test

Cement 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 area, whereas the first measures

Effect of grinding method and particle size distribution

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.
