Estimate the quantities of cement, sand, and coarse aggregate per m of concrete if minimum void ratios are 60%, 40% and 45%, respectively, and the material proportions by volume are as follows : (i) 1 part cement : 2 parts sand : 4 parts aggregate, and water-cement ratio = 0.55. %3D (ii) 1 part cement : 1.5 parts sand : 3 parts aggregate, and water-cement ratio = 0.42. Densities of cement, sand and coarse aggregate may be taken as 1500 kg/m3. 1700 kg/m³ and 1600 kg/m³.
