Cement Calculator
Result
Cement Calculator — free online calculator.
Formula
- Cement Calculator calculates its result from Aggregate Ratio, Sand Ratio, Volume. It uses the formula Cement fraction = 1 / (1 + sand_ratio + aggregate_ratio); Cement kg = Volume × 1500 × cement_fraction; Bags = ceil(cement_kg / 50). Change any input to recalculate the result instantly.
- The main inputs are Concrete Grade / Mix Ratio, Concrete Volume. Enter them in the units and format shown in the calculator.
- Keep measurements and project assumptions consistent before comparing or combining values.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Cement
- Concrete Grade / Mix Ratio: M20:1:1.5:3
- Concrete Volume: 1
Using Aggregate Ratio = 5, Sand Ratio = 5, Volume = 4, the calculated result is 11.
