Testing of cement physical tests is 4031 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.
Fineness of cement blaine air permeability test the fineness of cement is measured as a specific surface by observed time taken for a fixed quantity of air flow through compacted cement bed specified dimension and porosity, the fineness of cement value is directly proportional to the time, unit is m2kg or cm2gm please refer bsen code 196.
Soundness test of cement the change in volume of cement after setting or hardening is caused due to the unsoundness of cement.The expansion of cement after setting causes disruption of the hardened mass and create severe difficulties concerning strength and durability of the structure.
Cement is obtained by grinding various raw materials after.The degree calcination to which cement is ground to smaller and smaller particles is called fineness of cement.The fineness of cement has an important on the rate of hydration and hence on the rate of role gain of strength and also on the rate of evolution of heat.
