Calculadora de losa de hormigón

Cómo funciona esta calculadora

Volume = length × width × depth. Purchase volume = volume × waste factor. Bags = round up(liters ÷ yield per bag).

Ejemplo resuelto

A 3 m × 2 m × 10 cm slab is 0.6 m³. With 10% waste it becomes 0.66 m³, or 660 L. At 12 L per bag, buy 55 bags.

Suposiciones a comprobar

The slab is a rectangular prism with uniform depth.
Bag yield must come from the product label.
This is a material-volume estimate, not structural design or building-code advice.

Preguntas frecuentes

Why add waste to concrete?

Subgrade variation, spillage, form dimensions, and ordering tolerances can leave a shortfall. Use a factor appropriate to your project and supplier.

Should I order bags or ready-mix?

That depends on project volume, access, labor, and local supply. This tool shows both volume and bag count so you can compare.

Does this calculator design the slab?

No. It estimates material volume only. Thickness, reinforcement, base preparation, drainage, and structural requirements need project-specific guidance.
