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

Concrete Grade Ratio (Cement: Sand: Coarse)

• M25 – (1:1:2)
