Formulas & Assumptions

Formulas used

  • V = L × W × HRectangular elements (columns, beams, footings)
  • V = (π × D² / 4) × HCircular columns and piles
  • V_total = Σ (V_i × N_i)Sum of elements × their count
  • V_final = V_total × (1 + Waste)Final volume including waste

Assumptions & reference values

  • Default valueDefault waste 5% when supplied from a ready-mix plant.
  • Editable assumptionCement content 250–400 kg/m³ by concrete grade (C15–C30).
  • Industry estimateMixing water ≈ 180 L per m³ (water/cement ≈ 0.50).
  • Industry estimateAggregate density 1.5–1.6 t/m³ is used only for weight conversion.
