Concrete Column Calculator

How to use it

1. Calculate volume unitario: 0.30m × 0.30m × 3m = 0.27m³ per column
2. Calculate volume total: 0.27m³ × 6 = 1.62m³
3. Calculate cement: 1.62m³ × 7 = 11.34 → 12 bags
4. Calculate steel: 1.62m³ × 160 kg/m³ = 259 kg
5. Calculate formwork: 4 caras × 0.30m × 3m × 6 = 21.6m²

Common mistakes

• ⚠️ Not Consider The length of solape of The barras verticales in empalmes
• ⚠️ Use estribos with separación excesiva (deberían ir more juntos in extremos)
• ⚠️ Omitir recubrimiento minimum of 3cm to proteger The steel

Worked example

Calculate materials for a concrete column 0.40m x 0.40m, 3m high with 100 kg/m³ steel density.

The column requires {volumen} m³ of concrete, {cement_sacos} bags of cement, {sand_m3} m³ of sand, {gravel_m3} m³ of gravel and {acero_kg} kg of steel reinforcement.
