• Abstract:

  Structural lightweight concrete has come of age as an important material in modern construction. It is being used in many and varied applications; such as, multi-story building frames, curtain walls, shells, folded plates, paraboloids, bridges, prestressed or precast elements and the like. In nearly every part of the country today we find structural lightweight aggregates available.Structural lightweight concrete is defined as a concrete with a 28 day compressive strength in excess of 2500 psi and an air dry weight of less than 115 pcf. Note that this is a definition not a specification. The major portion of structural lightweight concrete has compressive strengths between 3000 and 4500 psi and weights between 95 and 110 pcf, but strengths in excess of 5000 psi are specified occasionally.
