The research on an effect of aluminium contents on detonation characteristics of ammonium nitrate explosives was carried out. Measurements of detonation velocity were performed. Parameters of blast waves produced by charges of the investigated explosives detonating in an open space were measured by the use of piezoelectric gauges. Quasi-static pressure measurements were conducted in a steel chamber of 0.15 m3 volume filled with air. Moreover, the heat of detonation was measured with a calorimetric set in a 5.6 dm3 bomb filled with argon. The results of measurements of QSP, detonation velocity and heat were compared with those obtained from thermochemical calculations.
