For M20 grade of concrete, the mix proportion of cement : sand : Coarse Aggregate is 1 : 1.5 : 3.
Therefore, for 1 kg of cement 1.5 kg of sand and 3 kg of gravel is required.
For 50 kg of cement (1.5 × 50) kg of sand and (3 × 50) kg of gravel is required.
Hence, for 50 kg of cement, (75 + 150) = 225 kg of dry aggregate is required.
Therefore, for 1 kg of cement 1.5 kg of sand and 3 kg of gravel is required.
For 50 kg of cement (1.5 × 50) kg of sand and (3 × 50) kg of gravel is required.
Hence, for 50 kg of cement, (75 + 150) = 225 kg of dry aggregate is required.
