Betonkolomrekenmachine

Volume voor ronde of rechthoekige betonkolommen.

Inleiding

Concrete Column Calculator — Volume for round or rectangular concrete columns. Enter Shape, Diameter / Width (m), Depth (m, rect only), Height (m), Number of columns, Waste (%) to get an instant, accurate result.

Formule

For round columns, volume = π × radius² × height (using the diameter you enter). For square/rectangular columns, volume = width × depth × height. Multiply by column count, then add a waste percentage allowance.

Stap voor stap

  1. Enter the Shape.
  2. Enter the Diameter / Width (m).
  3. Enter the Depth (m, rect only).
  4. Enter the Height (m).
  5. Enter the Number of columns.
  6. Enter the Waste (%).
  7. Click Calculate to see your result instantly.

Praktijkvoorbeeld

Example: With Shape = round, Diameter / Width (m) = 0.4, Depth (m, rect only) = 0.3, Height (m) = 3, Number of columns = 4, Waste (%) = 5, the Concrete Column Calculator gives Volume M3: 1.5834, Volume Without Waste M3: 1.508, Volume Cubic Yards: 2.071.

Veelgestelde Vragen

How is a round column different from a square one in this calculator?
Round columns use the circle-area formula (π × r²) based on diameter, while square/rectangular columns simply multiply width by depth.
Why multiply by column count?
Most projects pour several identical columns at once, so total volume scales directly with how many you need.
What inputs does the Concrete Column Calculator need?
You'll need to provide: Shape, Diameter / Width (m), Depth (m, rect only), Height (m), Number of columns, Waste (%). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Concrete Column Calculator?
The Concrete Column Calculator applies the formula exactly as calculated — For round columns, volume = π × radius² × height (using the diameter you enter). For square/rectangular columns, volume = width × depth × height. Multiply by column count, then add a waste percentage allowance. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Concrete Column Calculator free to use?
Yes, the Concrete Column Calculator is completely free, requires no signup, and runs instantly in your browser.

Over Betonkolomrekenmachine

The Concrete Column Calculator uses a real, verifiable formula — For round columns, volume = π × radius² × height (using the diameter you enter). For square/rectangular columns, volume = width × depth × height. Multiply by column count, then add a waste percentage allowance. — so results are accurate every time, not an approximation.
