Understanding Structural Lightweight Concrete Concrete ...

Aug 01, 1965  Understanding Structural Lightweight Concrete. 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.
