FINENESS TEST ON CEMENT. Piratical size of the cement is directly affecting the strength of the concrete. Finer partials react very quickly than the comparatively large particles. Further, fine cement has a greater surface area and hence faster the development of strength. There are two methods of testing of fineness of cement. By sieving

And after testing, you found the retained weight of cement on the sieve, Let it be 65 grams (w2). Now put the values in the formula; % of retained weight of cement = (65/1000) x 100. SO, the result of a fineness test of cement will be 6.5 % which is below the IS value (10%) and hence cement is in good condition.
