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.

## Inputs and controls

* Wet volume. Allowed range: 0.001 to 1000000
* Volume unit: Cubic feet; Cubic metres; Litres; Cubic yards
* Ordering allowance (%). Allowed range: 0 to 100. Added once to the measured requirement.
* Cement parts. Allowed range: 0.001 to 100
* Sand parts. Allowed range: 0 to 100
* Crush parts. Allowed range: 0 to 100
* Dry volume factor. Allowed range: 1 to 3. Editable estimating assumption, not a strength specification.
* Cement bag mass (kg). Allowed range: 1 to 1000
* Loose cement density (kg/m³). Allowed range: 100 to 5000
* Cement bag price (PKR / bag). Allowed range: 0 to 1000000000. Optional. Enter your own supplier quote.
* Sand price (PKR / cft). Allowed range: 0 to 1000000000. Optional. Enter your own supplier quote.
* Crush price (PKR / cft). Allowed range: 0 to 1000000000. Optional. Enter your own supplier quote.

## How to use

* 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 use this tool

Keeping the mix proportions visible makes it easier to compare material requirements when the nominal ratio or purchase basis changes.


## Before relying on the result

Nominal volume proportions are for material estimates, not a designed structural mix.


## Tool limitations

Nominal volume proportions are for material estimates, not a designed structural mix.

## Questions

### 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.
