조적조 건물의 내진보강에는 조적조 고유의 외관을 보존하면서 내진성능 향상 및 구조적 보강을 하는 것이 중요하기 때문에 초고성능 콘크리트(Ultra High Performance Concrete, UHPC)의 높은 역학적 성능 및 디자인 자유도에 주목하여 UHPC를 내진보강용 소재로 활용하기 위한 연구의 일환으로 비보강 조적벽체 시험체와 UHPC 패널 보강 조적벽체 시험체를 제작하여 내진성능평가 실험을 진행하였다.

We attempted to examine field applicability by manufacturing panels using UHPC and conducting mock-up tests. Mock-up testing was conducted at the Busan location. To observe field applicability over a long period of time, it was produced and installed identically to actual panels

콘크리트 체적에 가장 많은 부분을 차지하는 골재는 최근 골재자원의 고갈 및 환경 규제강화 등으로 수급상황이 어려워지고 있는 상황이다. 특히 골재 업체에서는 이윤추구를 목적으로 채취시 골재에 포함된 토분을 제거하지 않은 채 시중에 유통되고 있는 실정이다. 이에 본 연구에서는 메틸렌블루 시험방법을 이용하여 잔골재를 분류하고, 콘크리트 물성 평가를 통하여 비교 분석하고자 하였다. 실험결과 토분이 함유된 잔골재를 사용할 경우 단위수량이 증가하고 공기량이 저하하여 콘크리트 품질저하를 야기하는 것으로 나타났다.

Appearance finish is important for amorphous buildings to maximize amorphousness, and GFRC, glass, and metal are mostly used as exterior materials for amorphous buildings currently applied. However, the existing exterior materials showed limitations in amorphous expression, texture, and color expression. In this study, a 3D stereoscopic panel mold was manufactured using the FDM method, one of the 3D printing technologies, and 3D stereoscopic panel production was reviewed using Ultra High Performance Concrete (UHPC), which has excellent physical and mechanical performance and expression. In order to overcome the limitations of unstructured expression, a UHPC 3D stereoscopic panel using the FDM method, one of the 3D printing technologies, was manufactured. Unlike steel molds, FRP molds, and EPS molds, the FDM method can be applied to various materials, and complex shapes are implemented. If it is used using recyclable materials as well as PLA filaments used in the FDM method, it will overcome the limitations of amorphous expression and activate the production of 3D stereoscopic panels that have secured eco-friendliness.

This research reviewed the status of binder removal depending on the heating temperature and duration by using the 3D sand mold as an electric heating method. In the case of the electric heating method, it was confirmed that a heating temperature of at least 800℃ or higher was required to remove the binder of the 3D sand mold, and the heating duration was confirmed to be about 10 minutes. Afterwards, it is considered necessary to further evaluate the additional binder removal method and the utilization of recycling silica in consideration of economic feasibility and productivity.
