Understanding This Calculator
Concrete Formulas
Volume and material estimation.
- Wet Volume = Length × Width × Depth
- Dry Volume = Wet Volume × 1.54 (Shrinkage factor)
- Cement Bags = (Cement Part / Total Part) × Dry Vol / 0.035 m³
Example 1
Slab: 5m × 4m × 0.15m (Vol = 3 m³)
- Dry Vol = 3 × 1.54 = 4.62 m³
- Cement (1:2:4 mix): 1/7 × 4.62 / 0.035 ≈ 19 bags
