Concrete Quantities Calculator
Calculate cement, sand and aggregate quantities for site-mixed concrete (1:2:3 mix).
Estimate only — not a substitute for a licensed tradesperson, a certified engineer, or sign-off from your local building surveyor. Verify against current standards and site conditions before ordering materials or starting work.
Result
- Cement (dry volume)
- 0.26m³
- Sand
- 0.51m³
- Aggregate
- 0.77m³
Uses a common 1:2:3 (cement:sand:aggregate) nominal mix ratio - adjust for the actual mix design specified.
