The air blast effect produced by high explosives with additives of various types and quantities was studied. To this end, air shock intensities and pressure profiles were recorded at certain distances from an unconfined charge. Among those additives which by their reaction with the gaseous products of the detonated explosive theoretically should increase the energy potential, aluminum and zirconium exhibit a positive effect while other substances such as boron react too slowly for strengthening the blast effect. An addition of aluminum (32 weight%) causes the shock wave pressure to increase by about 15% and the momentum by 30% as compared with the pure explosive.
