Cement Calculator
Estimate the cement portion of a user-entered concrete mix and project volume.
Results
Project concrete volume
—
Estimated dry mix volume
—
Cement portion volume
—
Estimated cement bags
—
Use the result as a planning estimate and verify manufacturer guidance, material data and project-specific requirements where relevant.
How it works
The calculator estimates wet project volume, applies the entered dry-volume factor, then allocates that dry volume according to the entered cement:sand:aggregate parts.
Limitations
- This does not specify a structural concrete mix. Use an approved mix design and product/manufacturer instructions for structural work.
- Bag yields and dry-volume factors vary by product and materials.
