Assume We need 1 m3 of wet volume concrete of M25 Mix, (Mix Ratio, M25 = 1: 1 : 2) So Total Parts = 1+1+2 = 4 Parts which gives Dry volume that means before adding water content. Volume of concrete = (1 Cement Part)/4 + (1 Sand Part)/4 + (2 Coarse Aggregate Part)/4. From the IS Code standard, Assuming the water-cement ratio for M20 is 0.5.
