Exact Cement Consumption Formula for RCC Column (M20 & M25)
Construction Estimator India thumb rules:
- 9″x9″x10ft = 6–7.5 bags | 12″x12″x10ft = 14–17.5 bags
Professional Formula:
- Volume (m³) = Length × Width × Height (all in meters)
- Cement bags = Volume × 8.6 bags/m³ (M25 columns)
- Add 8% wastage + 12% for hooks/lappets.
Example: 9″x12″x10ft = (0.23×0.3×3.05)m³ = 0.21 m³ × 8.6 = 1.8 bags/column × 8 columns = 14–18 bags total.
