Abstract

Fiber reinforced lightweight concrete composites employ less than 4% by volume of reinforcing fibers in conjunction with small particulate lightweight aggregates or voids, and cure to composites which exhibit high tensile strain and strain hardening behavior. The composites are useful for numerous structures in civil engineering.
