1. TESTS ON CEMENT 1.1 FINENESS AIM To determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) - 1996. PRINCIPLE The fineness of cement is measured by sieving it through a standard sieve. The proportion of cement, the grain sizes of which, is larger than the specified mesh size is thus determined. APPARATUS FIG. 1 : IS SIEVE i) 90µm IS Sieve ii) Balance capable of weighing 10g to the nearest 10mg iii) A nylon or pure bristle brush, preferably with 25 to 40mm bristle, for cleaning the sieve 1
