Title: Low-Density High-Performance Concrete

Abstract:This paper presents three examples of low density, all lightweight aggregate concrete applications. These applications represent "high performance" concrete because the concrete properties could no be achieved with the usual materials and methods. Each example used rotary kiln produced expanded clay lightweight aggregates to obtain concrete densities as low as 75 lb/ft3. Where required, relatively high strength concrete (6000 psi) was produced. In another instance, the compressive strength was purposely limited to less than 3000 psi. In each case the concrete met the needs of the user, resulting in significant cost savings.
