From the table, we know the water-cement ratio is 0.55 for M20. We take 0.55 as a ratio of W/C. M20 is a volumetric mixing, so we have to take 0.55 of water in volume of cement. Therefore, the unit weight of cement = 1440 kg/m 3. Quantity of water = 0.55 x 50/1.44 = 19.1 Liters (1 bag cement = 50 Kg)

Water-Cement Ratio as per Weight. A certain minimum proportion of water is necessary to hydrate the cement completely.To create the concrete sufficiently workable to be placed in position, some more water is needed. So long as the concrete is sufficiently workable, for the way of placing used, its strength depends on the proportion of water to the cement in the mix.
