### 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.

For years, designers have been specifying an f’m equal to 1500 psi with Type S mortar using the unit strength method. According to the Code this would require a block compressive strength of 1900 psi. Recently on projects, some designers are now specifying a higher f’m, i.e., 2000 psi, 2500 psi and 3000 psi with Type S mortar.
