Cement & Concrete Mix Calculator
Cement & Concrete Mix Calculator
Split a nominal volume mix into cement, sand and crush.
A nominal mix estimate helps turn a concrete volume into a shopping quantity for cement, sand and crush.
Enter the intended volume and chosen proportions, then check the material units before buying. A volume ratio is a planning input, not proof of structural performance.
How to use Cement & Concrete Mix Calculator
- Choose volume unit. Enter wet volume and ordering allowance.
- Enter cement parts, sand parts, crush parts and dry volume factor.
- Enter cement bag mass and loose cement density.
- Enter cement bag price, sand price and crush price.
- Select Calculate estimate. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why choose this tool?
Keeping the mix proportions visible makes it easier to compare material requirements when the nominal ratio or purchase basis changes.
Before you use the result
Nominal volume proportions are for material estimates, not a designed structural mix.
Questions about Cement & Concrete Mix Calculator
Can I use the result as a structural mix design?
No. A designed concrete mix needs material testing and specified performance. Use these quantities for preliminary material planning, with the mix approved separately.
What should I check before using Cement & Concrete Mix Calculator?
Check Wet volume, Volume unit, Ordering allowance and Cement parts. Use the exact units shown beside the controls and replace any example values with your own inputs.
