Damage effects of explosion of RDX-based aluminized explosives in concrete

In order to investigate the damage effect of aluminized explosives in concrete, three types of aluminized explosive with different aluminum contents were blasted on small concrete targets. High speed camera was used to capture the blasting progress. Experimental results show that the depth of charge has important influence on the damage, and the damage effect at 30 cm buried depth is more serious than 10 cm buried depth. The aluminized explosives with aluminum content 15% has the best damage effect at 10 cm buried depth, which indicates that modest amounts of aluminum can increase the concrete blasting performance of aluminized explosives.
