Types Of Concrete Mix Ratio Design And Their Strengths

Types Of Concrete Mix Ratio Design And Their Strengths

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.
