Enter your project values, then press Calculate.

How this calculator works

Estimate cement, sand and aggregate from concrete volume and nominal mix proportions.

dry volume = wet volume × factor; constituents split by mix ratio

How to use the Cement Calculator

1. Enter project inputs

  • Concrete volume (m³)
  • Dry-volume factor
  • Cement ratio
  • Sand ratio
  • Aggregate ratio
  • Cement bag weight (kg)

2. Review the results

  • Cement
  • Cement bags
  • Sand
  • Aggregate

3. Check the calculation

The calculator uses the following core relationship:

dry volume = wet volume × factor; constituents split by mix ratio

Estimating note: Actual material quantities can vary with site conditions, detailing, product dimensions, installation method, and waste.
