Calcolatore di Calcestruzzo

Stima m³ e sacchi di calcestruzzo per qualsiasi soletta.

Introduzione

Concrete Calculator — Estimate m³ and bags of concrete for any slab. Enter Length (m), Width (m), Thickness (m), Waste (%) to get an instant, accurate result.

Formula

Volume = length × width × thickness, plus a waste percentage allowance; bag count assumes ~2500 kg/m³ density at 40 kg per bag.

Passo dopo passo

  1. Enter the Length (m).
  2. Enter the Width (m).
  3. Enter the Thickness (m).
  4. Enter the Waste (%).
  5. Click Calculate to see your result instantly.

Esempio pratico

Example: With Length (m) = 5, Width (m) = 4, Thickness (m) = 0.1, Waste (%) = 10, the Concrete Calculator gives Volume M3: 2.2, Volume Without Waste: 2, Bags 40kg: 138.

Domande Frequenti

Why add a waste percentage?
To account for spillage, over-excavation, and uneven forms — 10% is a common default allowance.
What if I use different-sized bags?
Scale the bag count proportionally — the volume figure stays accurate regardless of bag size.
What inputs does the Concrete Calculator need?
You'll need to provide: Length (m), Width (m), Thickness (m), 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 Calculator?
The Concrete Calculator applies the formula exactly as calculated — Volume = length × width × thickness, plus a waste percentage allowance; bag count assumes ~2500 kg/m³ density at 40 kg per bag. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Concrete Calculator free to use?
Yes, the Concrete Calculator is completely free, requires no signup, and runs instantly in your browser.

Informazioni su Calcolatore di Calcestruzzo

The Concrete Calculator uses a real, verifiable formula — Volume = length × width × thickness, plus a waste percentage allowance; bag count assumes ~2500 kg/m³ density at 40 kg per bag. — so results are accurate every time, not an approximation.
