Strength of Concrete (PSI) | ProMatcher

Strength of Concrete (PSI) PSI is a measure of compressive strength, or the ability of the material to carry loads and handle compression. Most concrete has a PSI rating of 2500 to 3000. This type of concrete can be used for sidewalks and residential driveways. This concrete is generally more affordable than higher strength concrete.
