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 this reason, the minimum compressive strength has been included in many specifications.
For M 15 grade of concrete mix, the ratio is 1:2:4, which means 1 part cement, 2 part sand, and 4 part aggregate used to prepare concrete mix with water. If you are using M 20 grade of concrete then you have to use a mix ratio of 1:1.5:3.
