Fire Resistance of Reinforced Polyamide Fiber Ultra High Strength(160MPa) Concrete
폴리아미드 섬유보강 초고강도(160MPa) 콘크리트의 내화성능
Abstract
Fiber reinforcement has been being widely used in concrete to enhance the mechanical properties and to reduce the micro-cracking caused by plastic and drying shrinkage. While researches has been focused on the benefits of fiber reinforcement, the properties of fiber reinforced concrete are strongly dependent on the type, shape and the amount of fibers in concrete.
분산제 코팅 및 단일형상을 가진 폴리아미드 섬유보강 콘크리트 기술을 적용하여 160MPa 초고강도 콘크리트의 내화성능을 평가한 결과, 콘크리트의 압송성능을 개선했을 뿐만 아니라 콘크리트의 내화성능 관리기준을 만족하였다.
