Calculate concrete volume for round solid columns using diameter, height and quantity. Columns are assumed solid circular cylinders. Deduct large voids separately. This browser-local calculator updates from numeric inputs and shows a labelled breakdown without uploading your data.

Calculate concrete volume for round solid columns using diameter, height and quantity. Columns are assumed solid circular cylinders. Deduct large voids separately.
Convert 150 mm to 0.15 m before multiplying 5×4×0.15, then add the chosen 5%.
Calculate slab concrete volume from length, width, thickness and floor openings. Subtract openings before multiplying by thickness; waste, reinforcement and supplier ordering are separate.
Measure concrete wall volume after deducting door and window openings. Openings are entered as surface area; wall thickness is assumed uniform.
Using these sample input values gives the first labelled output above. Gross rectangular volume; deduct overlaps with columns and slabs separately.
No. Replace the examples with your real values. Gross rectangular volume; deduct overlaps with columns and slabs separately.
Estimate rectangular continuous footing concrete by run length, footing width and depth. The result assumes a constant rectangular footing section, not stepped or sloped excavation.
Using these sample input values gives the first labelled output above. Uniform cylindrical bore geometry only; excludes widened base and overruns.
No. Replace the examples with your real values. Uniform cylindrical bore geometry only; excludes widened base and overruns.
Estimate full bag count from target concrete volume and product yield per bag. Use the yield printed on the actual product. Do not infer yield from bag weight alone.
