Abstract

Increasing of waste FRP (fiber reinforced plastics) has caused environmental problems. Recently, the technology of making fibers from waste FRP, which can be used to reinforce the concrete, was developed and the reinforced concretes were tested to study the structural performance. The purpose of this study is to investigate the effect of the powder, obtained together with F-fiber from the waste FRP, on the compressive strength and the fire resistance performance as in the high strength concrete. Strength tests show that the use of recycled FRP powder does not reduce the compressive strength of high strength concrete if the volume fraction of FRP powder is less than 0.7%. Electric furnace test results also show that the use of recycled FRP powder may increase the fire resistance performance of high strength concrete significantly.

폐 FRP 양의 증가는 환경적 문제를 일으키고 있다. 최근 폐 FRP로부터 콘크리트를 보강시킬 수 있는 섬유를 만들 수 있는 기술이 개발되었으며, 재활용 섬유로 강화된 콘크리트 제품의 구조적 성능을 연구하기 위한 시험도 수행되었다. 본 연구의 목적은 폐 FRP에서 생성되는 재활용 섬유 분진이 고강도 콘크리트의 압축강도와 내화성능에 주는 영향을 연구하는 것이다. 실험적 강도 측정 결과 재활용 섬유 분진의 부피 분율이 0.7%보다 작으면 그 분진을 사용하더라도 고강도 콘크리트의 압축강도가 감소하지 않았다. 전기로 시험 결과 역시 재활용 섬유 분진의 사용으로 고강도 콘크리트의 내화성이 크게 향상될 수 있음을 보였다.
