Evaluation on the Blast Resistance of Fiber Reinforced Concrete
Recently, the damaged building and loss of life have been increasing by man-made disasters. In this study, the blast resistance performance of fiber reinforced concrete against explosion was evaluated by the emulsion explosive and AUTODYN. The concrete without fiber was penetrated by emulsion explosive of 4605 kJ/kg and its back side was fractured heavily. The concretes with PVA, PE and Steel fiber have a higher blast resistance than that of concrete without fiber. Consequentially, the blast resistance of concrete was analyzed from viewpoint of fracture mode by AUTODYN and it was concluded that the fiber content is a beneficial for the blast resistance performance of concrete.
