Abstract

In this study, marine waste recycling plastic panels (MWRPPs) were proposed for the continuous and large-scale treatment of marine waste as concrete reinforcement. To verify the effectiveness of concrete reinforcement on MWRPPs, the effect of the anchorage method of MWRPPs on the bond behavior between concrete and MWRPPs was investigated. Three anchorage methods (E, EU, EA) were used to anchorage MWRPPs, combining epoxy (E), U-shape wrapping (U-wrap, U) and epoxy anchor (A) methods. The effect of the anchorage method on the bond behavior of MWRPPs was investigated through a single shear type test, which is widely used to evaluate the bonding behavior of fiber reinforced plastic sheets. U-wrap and epoxy anchors were found to improve the bond behavior between concrete and MWRPPs. The maximum shear strength between concrete and MWRPPs was highest at 0.94 MPa in EU where epoxy and U-wrap were applied, but the fracture energy was highest at 386.86 kPa-mm in EA where epoxy and epoxy anchors were applied. In this study, the optimal anchorage method for MWRPPs was determined to be EA, which uses epoxy and epoxy anchors to anchor MWRPP to the concrete surface.

본 연구에서는 콘크리트 보강재로서 해양쓰레기를 지속적이고 다량 처리할 수 있는 해양쓰레기 재활용 플라스틱 패널(marine waste recycling plastic panels, MWRPPs)이 제안되었다. MWRPPs에 대한 콘크리트 보강 효과를 검증하기 위해 MWRPPs의 정착 방법이 콘크리트와 MWRPPs 사이 부착 거동에 미치는 영향을 조사하였다. MWRPPs의 정착에는 에폭시(epoxy, E), U-shape wrapping(U-wrap, U), 그리고 에폭시 앵커(epoxy anchor, A) 방법을 조합한 세 가지 정착 방법(E, EU, EA)이 사용되었다. 정착 방법이 MWRPPs의 부착거동에 미치는 영향은 FRP sheet의 부착 거동 평가에 널리 사용되는 single shear type test를 통해 조사하였다. U-wrap 그리고 에폭시 앵커는 콘크리트와 MWRPPs 사이 부착 거동을 개선 시키는 것으로 확인되었다. 콘크리트와 MWRPPs 사이 최대 전단 강도는 에폭시와 U-wrap이 동시에 적용된 EU가 0.94 MPa으로 가장 높았으나, fracture energy는 에폭시와 에폭시 앵커가 동시에 적용된 EA가 386.86 kPa-mm으로 가장 높았다. 본 연구에서 MWRPPs에 대한 최적의 정착방법은 에폭시와 에폭시 앵커를 사용해 MWRPPs를 콘크리트 표면에 정착시킨 EA로 도출되었다.
