Abstract

When an explosion occurs in a concrete structure, debris throw is one of the major hazards and dominates the safety distances. To gain insight into concrete break-up, a series of one-way spanning clamped concrete slabs exposed to internal blast were tested under various loading densities. A combination of special powerful X-ray pulsars, high-speed video and strain gauges are employed to capture the initial concrete de- formation and its subsequent break-up process. An overview of the tests, the results and the interpretation of the break-up process are presented in this paper.
