· difference between a typical 3000 PSI mix and a typical 4000 PSI mix is that there is approximately 100 pounds more of cementious material and approximately 85 pounds less sand in the 4000 pound mix. Cement is the sliding agent in concrete while sand is abrasive which therefore makes the 4000 pound mix pump easier.

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.) PSI. Most concrete has a PSI rating of 2500 to 3000. This type of concrete can be used for sidewalks and residential driveways.
