| Zusammenfassung: | In this study, new polypropylene fiber was developed for shotcrete and concrete reinforcement, by treating the surface of the polypropylene by maleic anhydride grafted polypropylene(mPP). Dispersiveness of the fiber was tested. Mechanical properties of fiber reinforced shotcrete was tested. 본 연구에서는 숏크리트 보강용으로 폴리프로필렌 섬유의 표면을 무수말레인산이 그라프트된 폴리프로필렌(mPP)으로 표면 개질 처리한 새로운 폴리프로필렌 섬유를 개발하고, 개발된 섬유의 분산성을 조사하였다. 이 보강섬유가 혼입된 숏크리트의 강도 특성을 조사하였다. |
