1 Cubic Meter Concrete Cement Sand Ratio
A 1 m³ concrete mix ratio tells you how much cement, sand, and aggregate to use by volume or weight. This quick reference shows the most common nominal mixes so you can estimate materials before ordering.
What Is 1 Cubic Meter Concrete Cement Sand Ratio?
A concrete mix ratio expresses the proportion of cement, sand, and aggregate needed to produce one cubic meter of concrete. For example, a 1:2:4 ratio means one part cement, two parts sand, and four parts aggregate by volume. The correct ratio determines the strength, durability, and workability of the finished concrete.
Formula
Dry volume = 1.54 x wet volume Component volume = (ratio / total ratio) x dry volume Cement bags = cement volume / bag yield
A common nominal mix for general concrete work is 1:2:4 (cement : sand : aggregate) by volume. Your mix ratio may vary by strength or local standard.
How the estimate works
- Concrete mixes are measured on dry volume. A typical dry volume factor is 1.54.
- Bag yield depends on bag size. A 50 kg bag is about 0.035 m³ of cement.
- Use the calculators below for an exact result based on your mix, bag size, and density.
How this is calculated
For 1 m³ of a 1:2:4 mix we apportion about 1/7 of the volume to cement, 2/7 to sand, 4/7 to aggregate, then convert cement volume to bags (about 6–7 bags of 50 kg) and adjust for wastage.

FAQ
- How do I calculate concrete mix by hand?
- Add the ratio parts, divide each part by the total, then multiply by 1.54 for dry volume.
- What is the formula for 1m³ concrete cement?
- Cement volume = (cement ratio / total ratio) x 1.54. Convert to bags by dividing by bag yield (about 0.035 m³ for a 50 kg bag).
- 1:2:4 vs 1:1.5:3 mix
- 1:2:4 is general purpose; 1:1.5:3 is stronger and used for slabs and columns.
- What units should I use?
- Use volume units (m³ or L) for sand and aggregate, and bags or kg for cement.
- Can I use this for small repairs?
- Yes. Scale the ratio down. For a 0.1 m³ patch, use roughly one-tenth of the 1 m³ quantities.
