Estimating concrete quantity involves calculating volume based on dimensions and considering waste factors.

• Measure dimensions: Length, width, and depth for footings, slabs, or columns.

• Use the formula: Volume = Length × Width × Depth.

• Example: For a footing 2m long, 1m wide, and 0.5m deep, Volume = 2 × 1 × 0.5 = 1m³.

• Consider waste: Add 10% to account for spillage and over-excavation.

• For complex shapes, break down into si...read more
