Uses and mix ratio of M20 grade of concrete. M20 concrete grade means, M refers to concrete mix, and numerical figure 20 represents its characteristics of compressive strength (fck) @28 Days curing that is 20MPa when tested with 15cm × 15cm × 15cm cube. It is prepared by taking mix ratio 1:1.5:3 (1 cement : 1 1/2 Sand : 3 Aggregate).
