The weaker the subgrade or the heavier the loads then the thicker the slab needs to be Concrete strength also comes into play but most slab concrete is around 3000 to 4000 psi so it s not a major factor The tensile strength of concrete is typically taken as 10 to 15% of the compressive strength so only about 400 or 500 psi Compare that
