Concrete – how much weight a specific sized concrete slab can carry

concreteslab

Say I have a portion of 10×10 feets. I need to put a concrete slab for that. The thickness of the slab will go 4 inches.

Is there a way to tell, how much weight this slab can carry?

Depending on the percentage of the portions in the mix , a fully cured slab of concrete should have a compressive strength of between 2200-5000 psi. So depending on what the slab needs to support will determine the thickness and configuration of the concrete. A standard residential driveway is commonly 4-6 inches thick concrete with re-enforced steel bars. A residential garage normally is constructed on a 4 inch mono-lithic re-barred slab. These are just generalizations and you should consider all extenuating factors for your project for your region.
