Compressive Strength of Cement and Test to find it

Mar 09, 2020 Assume the test specimen is of 28 days old and max compression load at which the specimen starts breaking is 165KN. As per above fig, Surface are is 50Sq.cm = 5000mm 2. 1 KN = 1000N = 165 x 1000 = 165000. As per formula, Compressive strength of cement = 165000/5000 = 33N/mm2. Hence, the Grade of cement is 33 Grade.
