Calculate concrete volume for slabs, footings, columns, and walls.
For estimation purposes only. Terms of Use
Concrete is typically ordered in cubic metres (or cubic yards in imperial) directly from the ready-mix supplier, not converted to weight.
A 10m × 6m slab at 150mm thick with an 8% waste factor:
Use this to estimate ready-mix concrete orders for slabs, footings, columns, or walls before placing a material order. Helps avoid running short mid-pour or over-ordering excess material.
Not a substitute for structural engineering calculations involving rebar, formwork design, or load capacity. Always follow approved structural drawings for anything load-bearing.
5-10% is standard for simple slabs and footings. Complex forms, irregular shapes, or pours with multiple trucks should use 10-15% to avoid running short.
A standard ready-mix truck carries approximately 7.5-8 m³ (around 10 cubic yards), though this varies by supplier and truck size.
No — rebar volume is negligible compared to total concrete volume and is not typically deducted from concrete orders.
