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.
Nominal Mix Ratio. In nominal mixed concrete, the proportion of mixing concrete ingredients is fixed and recommended by standard codes. 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.

28 kwi 2024 · The 1:2:4 ratio refers to the proportions by volume of the main ingredients in a concrete mix: 1 part Portland cement: The binding agent that reacts with water to form a paste, eventually...
4 sty 2024 · Concrete mix ratios are crucial for the right consistency, and the basic ingredients include aggregate, sand, cement powder, and water. Common ratios are 1-2-3 and 1-2-4, with higher sand content resulting in weaker concrete and more aggregate leading to increased strength.
19 lis 2023 · The proper concrete mixing ratios are 1:2:3, 1:3:3, 1:2:4 for cement, sand, and stone. Mixing ratios are based on what psi concrete you need. Mixing ratio chart
The strength of nominal mix concrete varied widely for given workability due to the variation of mix ingredients. M 15 (1:2:4), M 20 (1:1.5:3) are the nominal mix ratio of concrete. Also, Read - Difference Between OPC and PPC Cement.
