## Formula

- Dry volume of concrete in m3 = 1.54 * wet volume of concrete in m3
- Dry volume of cement = (cement ratio / sum of ratio) * wet volume of concrete in m3 * 1.54
- Dry volume of fine aggregate = (sand ratio / sum of ratio) * wet volume of concrete in m3 * 1.54
- Dry volume of coarse aggregate = (coarse ratio / sum of ratio) * wet volume of concrete in m3 * 1.54
- Weight of cement in kgs = Dry volume of cement in m3 * 1440
- Amount of water needed = water to cement ratio * Weight of cement in kgs

## Concrete Grade Ratio (Cement: Sand: Coarse)

- M25 – (1:1:2)
- M20 – (1:1.5:3)
- M15 – (1:2:4)
- M10 – (1:3:6)
- M7.5 – (1:4:8)
- M5 – (1:5:10)
