Concrete mix ratios are prescribed ratio of cement, sand and aggregate to get the desired strength in concrete. The volumetric mix ratio of M20 concrete is, hence 1 part of cement, part of sand and 3 part of aggregate in volume is needed to prepare M20 grade concrete.
Concrete: It is the mixture of coarse agrregates, fine aggregates, cement and water in a proper proportion. The proportion however depends upon the type of construction. The proportion for residential, commercial, road and highways, bridges etc all are different depending upon the load bearing capacity.
