Find the quantities of cement, fine aggregates (FA) and coarse aggregates (CA) for 1 m³ of concrete. The void ratio in cement is 60%, in FA is 40% and in CA is 44%. Take Materials properties as: Mix is 1:2:4 with water-cement ratio of 0.59. One bag of cement weighs 50 kg (neglecting the empty weight of bag) and density of cement is 1440 kg/m³. Density of FA is 1780 kg/m³ and coarse aggregate (CA) is 1650 kg/m³. Volume of one bag of cement is 34.7 litres. Assume volume of air in concrete as 3% per m³ of concrete.
