Structural Lightweight Aggregate Concrete

With a typical unit weight of 90 to 120 pounds per cubic foot (pcf) and a compressive strength from 2500 psi to more than 8000 psi, structural lightweight concrete is a versatile building material. Since it is generally 20% to 40% lighter than normalweight concrete, a structure's dead load can be reduced, its foundation costs lowered, and its concrete and rebar needs lessened. …
