Metric Self-Mix Concrete Calculator
The Self Mix Concrete Calculator (Metric) helps you determine the correct mix ratios for cement, sand, gravel, and water for a specified volume of concrete. By inputting the desired total volume and cement-to-water ratio, the calculator provides the volume and weight of each component and the total weight of the concrete mix.
Self-Mix Metric Calculator
Calculator
- enter the cement, sand, and gravel ratio for the concrete mix
- the cement-to-water ratio
- the volume of concrete required in cubic meters
Results
- volume of the dry materials in cubic metres
- the volume in cubic metres and the weight in kilograms of the cement
- the volume in cubic metres and the weight in kilograms of the sand
- the volume in cubic metres and the weight in kilograms of the gravel
- the water volume in cubic meters, its weight in kilograms, and the volume in litres
- the total weight of the concrete mix in kilograms
Example Calculation
Mix Ratio: 1 (cement) + 2 (sand) + 4 (gravel) = 7 parts Cement/Water Ratio = 0.5 Concrete volume = 6.5 m³Dry Ingredients Volume = 10 m³
Cement Volume: 1/7 * 10 = 1.42857 m³ Cement Weight: 1.42857 m³ * 1440 kg/m³ = 2057 kg Sand Volume: 2/7 * 10 = 2.857 m³ Sand Weight: 2.857 m³ * 1536.491 kg/m³ = 4389.97 kg Gravel Volume: 4/7 * 10 * = 5.7 m³ Gravel Weight: 5.7 m³ * 1589.981 kg/m³ = 9085.6 kg Water Volume = 1.42857 m³ * 0.5 = 0.714285 m³ Water Weight: 0.714285 m³ * 1000 kg/m³ = 714.285 kg Cement volume and weight: 1.4 m³ - 2057 kg. Sand volume and weight: 2.9 m³ - 4389 kg. Gravel volume and weight: 5.7 m³ - 9086 kg Water Volume and weight: 0.7 m³ - 714 kg Total Weight of Concrete: 2057 + 4389 + 9086 + 714 = 16246 kgFor ten cubic meters of concrete, you would need:
2057 kg of cement 4389 kg of sand 9086 kg of gravel 714 kg of waterTotal weight: 16249 kg
This tool helps you accurately mix concrete for construction projects using precise ratios and metric measurements.
