Crushing Strength Of M30

Sep 06, 2016 383.2 kg/m 3 300 kg/m 3, hence, OK. This value is to be checked for durability requirement from IS: 456. In the present example against mild exposure and for the case of reinforced concrete the minimum cement content is 300 kg/m 3 which is less than 383.2 kg/m 3. Hence cement content adopted = 383.2 kg/m 3.
