Concrete recycling Heavy Equipment Forums

Nov 11, 2013  So they rate concrete in psi right? Like 2500 psi to like 4000 psi, or something like that. Is that relevant to the breaking strength? The rock I am crushing daily is anywhere from 29k psi to 40k psi compressive strength. If I'm thinking along the right lines, that would make concrete much easier to crush than my material.

Subgrades Subbases for Concrete Slabs - The Concrete Network

Jul 31, 2018  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 to the tensile strength of Grade 60 rebar, which is 60,000 psi.
