A studies of the failure mode on reactive powder concrete plates subjected to impact loading

The reactive powder concrete (RPC), which is a new composite that has been developed in recent years, is a special mixture that has been cured especially to have a higher compressive strength than concrete (-20OMPa). Adding a few steel fibers improves its compressive strength, splitting tensile strength and flexural strength, its impact-resistance and its toughness. It is thus expected to be used to protect military facilities and nuclear power plants. Accordingly, this paper aims to conduct a study by high-velocity impact experiments to assess the resistance of the ultra-high-strength concrete targets subject to impact. Test variables include the impact velocity and amount of steel fibers added. The experimental results show that RPC plate relatively on normal concrete (NC) plate, because of their higher compressive strength, cause fragility nature to increase relatively, but after adding a small amount of steel fiber, the significant improvement impact resistance was observed in target plates.
