DYNAMIC ENERGY-ABSORBING CHARACTERISTICS OF LIGHTWEIGHT VERMICULITE CONCRETE

Abstract

The dynamic energy-absorption characteristics of confined lightweight vermiculite concrete are presented in the form of stress-strain and stress-time curves. In addition, data are included which show the effects of impact velocity and impact mass weight on these characteristics. Stress-strain and energy-absorption characteristics are discussed. A comparison is made between a dynamic and a static stress-strain curve for this material. For a cement to vermiculite mix of 1 to 8, the initial peak crushing stress is between 420 and 570 psi, and the average crushing stress to 30% strain is between 350 and 450 psi. The energy dissipated to 30% strain is between 8.8 and 10.9 ft-lb/cu in.
