Column Concrete Volume Calculator

Column concrete volume calculator — concrete, cement, sand and aggregate for RCC pillars. Use the free Column Concrete Volume Calculator below — enter your values and get instant results, right in your browser. Volume (cu ft) = columns × (length/12) × (width/12) × height. Dry volume = wet × 1.52; cement bags = dry(m³) × 1/mix-sum × 28.8; sand and aggregate by mix parts.

How to use the Column Concrete Volume Calculator

Columns carry the whole building, so their concrete deserves an exact material count — a short pour here cannot be topped up tomorrow without a weak joint. This column concrete volume calculator multiplies your column cross-section by height and count, then applies the 1.52 dry-volume factor and splits the mix into cement bags, sand and aggregate. It handles the standard 1:2:4 column mix and the richer 1:1.5:3 where engineers specify it, giving the complete pour list for all columns at once.

  1. Enter the number of identical columns.
  2. Enter the column length and width in inches (e.g. 12 × 12).
  3. Enter the column height in feet from footing or slab to beam.
  4. Select the concrete mix specified by your engineer.
  5. Click Calculate to see concrete volume, cement, sand and aggregate.

Formula

Volume (cu ft) = columns × (length/12) × (width/12) × height. Dry volume = wet × 1.52; cement bags = dry(m³) × 1/mix-sum × 28.8; sand and aggregate by mix parts.

Worked example

Six 12×12 inch columns, 10 ft high: volume = 6 × 1 × 1 × 10 = 60 cu ft. At 1:2:4, dry volume = 91.2 cu ft (2.58 m³): cement = 10.6 bags, sand = 26 cu ft, aggregate = 52.1 cu ft.

Frequently asked questions

Exactly 10 cubic feet of wet concrete, needing about 1.8 bags of cement with 1:2:4 mix.

1:2:4 is standard for house columns; engineers specify 1:1.5:3 for heavily loaded columns.

Yes — each column should be poured continuously to avoid cold joints; that is why an exact material count matters.
