M20 Concrete Ratio: – The mix ratio of M20 grade concrete is 1:1.5:3, consisting of 1 part cement, 1.5 parts sand ( fine aggregate) and 3 parts aggregate ( gravel ). Apart from that water is used to make the concrete. M20 concrete ratio is 1:1.5:3 by volume. It indicates the nominal ratio of cement, sand and aggregate.
