혼입섬유 종류에 따른 섬유보강 콘크리트의 내폭성능 평가

Recently, building structure damage and number of lives lost by bomb terror is increasing. Therefore, in this study, it is aimed to present basic data for blast resistance performance of concrete structure with intermediate space by fiber reinforced mortar panel and explosion test. Fiber reinforced mortar specimen is produced by using PVA, PE and STF fiber. Distance between blast resistance panel and structure is each 0, 10, 30 and 50㎜. In the explosion experimental, blast resistance of mortar has greatly improved by fiber reinforced. When blast resistance panel is installed in the structure, blast resistance has improved in more than 10㎜ air space.
