The article is dedicated to the research and development of the ammonium-perchlorate-based pyrotechnic composition used for the safe destruction of artificial concrete objects. Ammonium perchlorate has been used as an oxidant of the pyrotechnic composition. Primarily, this is conditioned by the powerfully destructive force of ammonium perchlorate; the application of perchlorate compounds enables obtaining the most energy-efficient compositions. The magnesium powder brand MPF-1 has been used as a fuel and the polyethylene as a fuel and gas-forming agent. The impacts of different amounts of magnesium powder on the properties of combustion of the ammonium-perchlo-rate-based pyrotechnic composition have been studied. The calculation and experimental data have shown that it is impractical to introduce more than 5 % of magnesium into the composition. Based on the study results, the ammonium-perchlorate-based pyrotechnic composition was elaborated in order to increase the efficiency and safety of blast jobs. The laboratory and landfill tests have confirmed the efficiency and safety of the use of pyrotechnic compositions for the destruction of artificial concrete objects. A concrete block was destroyed without the scattering of fragments and the formation and propagation of a blast airwave. Therefore, ensuring the safety of blast jobs involving pyrotechnic compositions is a first-priority task, which will prevent the generation of harmful and poisonous gases and the brisant action of explosion.
