As in IS 456: 1964 and IS 456: 1978 it is noted that 1 N/mm 2 = 10 kg/cm 2. ∴ M 10, M 15, etc grades of concrete of IS 456: 2000 corresponds to M 100, M 150 grades of concrete respectively of IS 456:1964. According to IS code: Bond stress for M20 grade concrete is 1.2 N/mm 2 or 12 kg/cm 2. ∴ For M15 it will be 1.0 N/mm 2 or 10 kg/cm 2.
