Concrete Mix Volume Calc is a verified engineering & build calculation tool on Calcify. Calculate wet & dry concrete volume (m³) and 50kg cement bags, sand, and aggregate for M15/M20/M25 slabs. All calculations execute locally in your browser with multi-currency support, visual breakdowns, and white-label client exports.
Dry Volume (1.54x): 5.54 m³ | Sand: 1.51 m³ | Aggregate: 3.02 m³
Wet_Vol = L × W × D; Dry_Vol = Wet_Vol × 1.54; Cement_Bags (50kg) = (Dry_Vol × Cement_Part / Mix_Sum) / 0.0347
Example Inputs: Slab / Footing Length (Meters): 6 m · Slab / Footing Width (Meters): 4 m · Slab Thickness / Depth (Meters): 0.15 m · Nominal Concrete Mix Grade: m20
Example Output: 50 kg Cement Bags & Wet Volume: 30 Bags (3.60 m³) (Dry Volume (1.54x): 5.54 m³ | Sand: 1.51 m³ | Aggregate: 3.02 m³)
The Concrete Mix Volume Calc on Calcify applies the verified mathematical formula: Wet_Vol = L × W × D; Dry_Vol = Wet_Vol × 1.54; Cement_Bags (50kg) = (Dry_Vol × Cement_Part / Mix_Sum) / 0.0347. Every input is validated in real time with multi-currency formatting to ensure zero rounding or division errors.
Uses standard 1.54 dry-to-wet concrete bulking factor and 0.0347 m³ per 50kg bag of OPC cement.
