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.

weight concrete is a versatile building material. Since it is generally 20% to 40% lighter than normalweight concrete (Ref. 2) , a structure's dead load can be re-duced, its foundation costs lowered, and its concrete and rebar needs lessened.

A structural light-weight concrete mix has a density of about 105 pounds per cubic foot compared to normal concrete with a density of 150 pounds per cubic foot. The light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less.
