Abstract: This paper presents the results from an experimental program which examines the behaviour of UHPFRC beams under simulated blast loads. As part of the study a series of three large-scale reinforced concrete beams are tested under blast loads using the Shock-tube at the University of Ottawa. The specimens include one beam built with conventional high-strength concrete (HSC) and two beams built with Compact Reinforced Composite, a proprietary UHPFRC. The effect of UHPFRC on blast behaviour is examined by comparing the mid-span displacements, blast resistance and failure mode of the beams. Overall the results confirm the superior blast resistance of UHPFRC when compared to conventional high-strength concrete. In addition to reducing displacements at equivalent blast loads, the use of UHPFRC in beams leads to an ability to resist greater blast loads. The addition of high-strength reinforcement in the UHPFRC beams further improves blast resistance.
