Abstract

To reduce the environmental load of the construction industry, there is a need to minimize construction and demolition by strengthening the eco-friendliness of building materials and extending the durable lifespan. Therefore, while many Hanok roof finishing methods have been proposed to address these problems, the current trend is to use the existing method due to issues such as economic feasibility, weight, and durability. The manufacturing method of clay roof tiles used as roofing materials for Hanok buildings is optimized by using a mixture of 64.5% Gyeongju clay, 15.0% kaolin, 15.0% FNS(Ferro Nickel Slag), and 5.5% MAS(Magnesia Aluminum Silicate) under optimal conditions. The results of the experiment involving firing at 1,125℃ showed that flexural strength of 12,102N, which is higher than the standard of KS F 3510, an absorption rate of 6.08%, a volume specific gravity of 2.15g/cm3, and the freeze-thaw properties were satisfied. A method for securing stable quality was studied.

건설산업의 환경부하를 최소화하기 위해서는 건축 자재의 친환경성을 강화하고 내구수명을 연장하여 신축 및 철거를 최소화의 필요성이 있다. 따라서 이러한 문제점을 개선하기 위해 많은 한옥의 지붕마감 공법이 제안되었지만 현재는 경제성, 무게, 내구성 등의 문제점으로 기존공법을 사용하는 추세이다. 한옥 건물의 지붕재로 사용되는 점토기와의 제조방법에 경주에서 생산된 기와용 점토와 고령토와 S사의 재활용 FNS(Ferro Nickel Slag) 활용하여 문제를 해결하고자 연구를 진행하여 한국전통 점토기와의 개발 특성과 재료를 연구하고 관련 기초자료를 제시한다.
