Strength of Concrete PSI ProMatcher

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.
