Calculate Cement Sand & Aggregate - M20, M15, M10, M5 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 1:1.5:3, hence 1 part of cement, 1.5 part of sand and 3 part of aggregate in volume is needed to prepare M20 grade concrete.
