Introduction :: Structural Concrete :: Norlite .

Structural Lightweight Concrete is a versatile building material typically with unit weights from 90 to 125 pounds per cubic foot and compressive strengths from 2,500 psi to more than 8,000 psi. Since it is generally 20% to 40% lighter than normalweight concrete, a structure's dead load can be reduced, its foundation costs lowered, and it's concrete and rebar lessened.
