Understanding Structural Lightweight Concrete Concrete ...

Aug 01, 1965  Structural lightweight concrete is defined as having a 28 day compressive strength in excess of 2,500 psi and a unit weight ranging from 85 or 90 pcf to 115 pcf. Generally speaking, concrete in this range of strength and weight is produced with expanded shales, clays, slates, and slags.

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.
