GRADE OF CONCRETE. Concrete of Grade is a mixture of Portland cement, water, and coarse and fine aggregates. It consolidates into a hard mas because of a chemical reaction called hydration between cement and water. Proportioning a concrete mix for a given purpose is thus the art of obtaining a suitable ratio of the various ingredients of concrete with the required properties at the lowest cost.

Concrete Mix Ratio by Volume. 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 1::3, hence 1 part of cement, part of sand and 3 part of aggregate in volume is needed to prepare M20 grade concrete.
