Ammunition storage magazines are a necessary component of our military logistics network. However in view of their contents provision must be made to prepare for the possibility of accidental explosion. Such explosions are likely to have a highly destructive effect on the immediate area due to debris being flung far and wide. This is all the more likely in densely-populated Singapore, which faces a land constraint. In light of this constraint, simply providing an arbitrarily large safety radius is sub-optimal. Hence this study was conceived to characterise the projectile behaviour of post impact debris, and assess the speed and angles at which the fragments would possess lethal velocity. The results of this study can be used to design structures in the vicinity of such ammunition magazines. This phase of the project examines the rebound and ricochet of concrete debris after impact with a hard surface. This study takes an experimental approach, firing pre-damaged 100mm chamfered concrete cubes onto a reinforced concrete slab. This project consists of two reports. This report will focus on the set up of the experiment and data collection process, while the writer’s partner’s report (Yap, L., 2016) will discuss the analysis of data and conclusions drawn.
