Nov 04, 2020 Answer by Mihir Salanke: Mix proportion for M25 grade of concrete is 1:1:2(cement:fine aggregates:coarse aggregates). So if you need 4cu.m of M25 concrete, we need to have 1cu.m of cement. So, theoretically, for 1cu.m of M25 concrete, we need to have 0.25cu.m of cement. But in practice, whenever we estimate quantity of cement for concrete

If you want detailed calculation you can refer this post for calculation procedure for Nominal mix concrete. Alleged M25 Mix Ratio = 1:1:2. The volume of cement required per cubic meter for M25 grade ratio concrete= (1 / (1+1+2)) * 1.5 = 0.375 m3. Bulk density of cement is 1440 kg/m3. Therefore weight of cement required = 0.375 * 1440 = 540 kg/m3.
