| Abstract |
This study experimentally evaluated the blast resistant performance of fiber reinforced concrete by emulsion explosive. To evaluate the blast resistant performance, we conduct the experiment of contact exploding emulsion explosive. As a result, bending and tensile performance depending on type of PVA, PE fiber(polyvinyl alcohol fiber, polyethylenefiber) and steel fiber affects reducing of rear side spall. In case of the specimen reinforcing fiber reinforced concrete panel on base concrete, intermediate space between base concrete and fiber reinforced concrete panel affects rear side spall. |
