Nominal mix ratios for concrete are 1:2:4 for M15, 1:1.5:3 for M20 etc. Standard Mixes or Ratio The nominal mixes of fixed cement-aggregate ratio (by volume) vary widely in strength and may result in under or over-rich mixes.
For concrete of 1:2:4 mix proportion, first two boxes of sand and one bag of cement should be dry-mixed thoroughly. Then, a dry mix of cement and sand is placed over a stack of 4 boxes of stone aggregates and the whole mixture is dry-mixed, turning at least three times to have a uniform mix.
