Concrete Volume Calculator
Work out the concrete for a footing, column or slab. Enter the dimensions and how many, pick the nominal mix grade, and get the volume plus indicative cement, sand and aggregate.
E.g. 4 identical column footings of 1 x 1 x 0.3 m.
Wet volume for 4 units.
Materials use a 1.54 dry-volume factor and the nominal M20 (1:1.5:3) ratio. Allow wastage and round up when ordering.
Indicative only. Nominal mixes are fine for small non-critical work, but structural concrete (footings, columns, retaining walls) should follow a design mix and reinforcement specified by a licensed structural engineer to IS 456. This tool does not set the grade, cover or steel for your structure — confirm with your engineer.
