About this calculator

Overview

Concrete columns are primary structural elements that transfer loads from slabs or beams to the foundation. This calculator helps determine the exact volume of concrete needed for any number of columns, ensuring you order the correct amount for your pour.

💡

Pro Tips

For round columns, 'Sonotubes' are the industry standard for easy forming.
Vibrate the concrete during the pour to eliminate air pockets (honeycombing) which weaken the column.
Always add 5% for waste to ensure you don't run short on the last column.

Fun Facts

"Circular columns are often more efficient at resisting axial loads."
"Reinforcing steel (rebar) usually takes up less than 5% of the column volume, but should be accounted for in large projects."
"The world's tallest concrete columns are in the Millau Viaduct in France, reaching nearly 800 feet (244 meters)."
