초록

최근 비정형 건축물의 비중이 증가함에 따라 거푸집 재사용이 불가하여 건설폐기물이 증가하고 있는 추세이다.
또한 비정형 건축물 건축 시 생산자의 숙련도에 따라 비정형 패널의 품질이 결정되며 이에 따른 정확한 공사비 측정불가 및 인건비 증대라는 문제점이 있다. 본 연구는 이러한비정형 건축물의 문제점을 보완하기 위하여 오차율이 적고작업성이 좋은 최적의 배합을 찾는 것을 목표로 실험을 진행한다.

영어초록

Recent developments in architectural technologies and programs have enabled architects to think creatively anddesign free-form architecture. however, there are many problems in the production technology of FCP(Free-FormConcrete Panel). In particular, reduced accuracy due to lack of free-form panel production technology can lead toredesign of buildings as a result, problems such as an increase in construction cost and period. Therefore, thisexperiment aimed to compensate the decrease of the accuracy according to the displacement difference and to derivethe proper mixing ratio for maintaining the shape during the free-form panel curing. In this study, molds were madeusing paraffin that is a recyclable phase change material. Concrete Panel is usually produced from Portland cement,dead burn magnesia, phosphate, borax and fine aggregate. In this study, four mixing ratios of FCP were selected aftereach material was blended to determine the proper blending ratio of the fluidity phase, the water absorption rate andthe water content of the test piece. FCP was fabricated on the basis of the selected four compounding ratios andthickness and error rate were measured. Based on the error rate of the measured FCP, the quality standard wassatisfied among the four compounding ratios.
