Formula and methodology
Formula: Cement volume = concrete volume×fraction; cement mass = volume×density; bags = mass/bag mass.
The fraction, density, and package size remain editable because real mix designs and products vary.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Concrete volume — m³; minimum 0; maximum 1000000
- Cement volume fraction — %; minimum 0; maximum 100
- Cement density — kg/m³; minimum 1.0E-6; maximum 1000000
- Bag mass — kg; minimum 1.0E-6; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Concrete volume | 2 |
| Cement volume fraction | 15 |
| Cement density | 1440 |
| Bag mass | 25 |
Cement mass = 432 kg, or 17.28 bags.
Assumptions and limits
- Volume and density use SI units, fraction is 0–100%, and bag mass is positive.
- The entered fraction is a volume fraction for a rough planning model.
- Mix design, aggregate grading, water-cement ratio, strength, shrinkage, labor, and local practice are not modeled.
