Last updated on by Editorial Staff

## Quick Guide to Use This Calculator

• Enter the volume of wet concrete to be produced in cubic meters.
• Select the water-to-cement ratio from the dropdown menu.
• Click the “Calculate” button to obtain results.
• To reset the form, click the “Reset” button.

## Formula

1. Dry volume of concrete in m3 = 1.54 * wet volume of concrete in m3
2. Dry volume of cement = (cement ratio / sum of ratio) * wet volume of concrete in m3 * 1.54
3. Dry volume of fine aggregate = (sand ratio / sum of ratio) * wet volume of concrete in m3 * 1.54
4. Dry volume of coarse aggregate = (coarse ratio / sum of ratio) * wet volume of concrete in m3 * 1.54
5. Weight of cement in kgs  =  Dry volume of cement in m3 * 1440
6. Amount of water needed = water to cement ratio * Weight of cement in kgs
