Abstract

In this paper the reactive powder concrete (RPC) behavior subjected to different explosion charges and also in different distance of explosion point has been investigated. Moreover, the effect of change in the thickness of RPC slab has been considered. In order to analytical simulation of RPC behavior against blast and also accuracy of results using ABAQUS software, a RPC slab studied in the literature has been verified. The obtained results are showed that the simulated model of RPC is match with literature one. In order to compare of resulted results of RPC slab a NSC slab has also simulated. Different scenarios of explosion in form of tow numerical examples have been considered. It’s noted that the NSC slab is supposed to be a reinforced concrete, whereas 2% volume of special short steel fibers were used in the RPC specimen. The acquired results of analysis have been showed that the RPC have better blast explosion resistance than reinforced normal strength concrete and can be used in built and strengthening of structures.
