You can easily calculate the concrete quantity for circular RCC structures.

In this calculator, you simply need to enter the slab’s diameter and thickness. The calculator automatically computes the concrete volume in cubic meters (m³).

Formula Used

Concrete Volume = π × (Diameter² / 4) × Thickness

Where:

π (Pi) = 3.1416
Diameter = Diameter of the circular slab (in meters)
Thickness = Thickness of the slab (in meters)
Example Calculation

Let’s assume:

Diameter = 6 m
Thickness = 0.15 m

Volume = 3.1416 × (6² ÷ 4) × 0.15

Volume = 4.24 m³

This means approximately 4.24 cubic meters of concrete will be required for the circular slab.
