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.
