    Strength Of Concrete (PSI) | ProMatcher

    the strength of concrete is measure in terms of pounds per square inch (or psi). psi is a measure of compressive strength, or the ability of the material to carry loads and handle compression. 1.) 2500-3000 psi. most concrete has a psi rating of 2500 to 3000. this type of concrete can be used for sidewalks and residential driveways.
