기술논문 : 유리섬유강화슬래그(Glass-fiber Reinforced Slag)의 경관석 성능 적합성 평가
윤복모 ( Bok Mo Yoon ),이용복 ( Yong Bok Lee ),구본학 ( Bon Hak Koo ) 한국환경복원기술학회(구 한국환경복원녹화기술학회) 2013 한국환경복원기술학회지 Vol.16 No.2
This study was carried out to verify the suitability of GRS(Glass-fiber Reinforced Slag) as natural type landscape stone according to the material property and structural safety performance standards. The structural safety performance of the GRS panel showed 12.4MPa and l6.2MPa each in flexural strength at 2 and 3% content of glass fiber while the flexural strength at 4 and 5% of glass fiber content showed 26.9MPa, and 30.2MPa, respectively, all satisfying the standards. In addition, air-dried gravity was found to be 1.82 -1.89 in measuring range at 2 -5% level of glass fiber content, satisfy the existing standards l.8-2.3.Tn structural safety performance, the range of flexural strength consequent on glass fiber content was surveyed to be 12.8 -30.2MPa, all satisfying the performance standards, while 10MPa and more while the compressive strength range was found to be 41.5 -53.3MPa, all satisfying the performance standards, 40- 6OMPa.This study judged the suitability of only the items for a property of matter of landscape stone GRS by applying the natural-form landscape stone GFRC material standard, but in case an installation constructed with GRS material comes into existence later, there should be comprehensive performance guidelines through the research on durability, landscape performance and environmental and ecological performance.

유리섬유강화콘크리트를 이용한 자연형 경관석의 성능기준 연구
윤복모,구본학,Yoon, Bok-Mo,Koo, Bon-Hak 한국조경학회 2012 韓國造景學會誌 Vol.40 No.5
본 연구는 자연형 경관석 GFRC를 대상으로 성능기준을 설정하기 위해 국내 외 성능관련 문헌 및 사례 등의 고찰을 통해 요구성능인 재료성능, 구조안전성능, 내구성능, 경관성능의 항목을 40인의 전문가 설문을 통해 선정하였고, 검증된 항목 및 성능기준을 제안하였다. 전문가 설문을 통해 요구 성능 중 재료성능(유리섬유 함유율, 기건비중), 구조안전성능(휨강도, 압축강도) 그리고 내구성능(균열, 내부식성), 경관성능(질감, 백화)을 각각 선정하였다. 기준이 존재하는 재료성능과 구조안전성능의 경우, 시험을 거쳐 기존 기준사례와 비교하여 최종 성능평가기준을 제시하였으며, 기준이 존재하지 않은 내구성능과 경관성능은 기 시공된 인공폭포 등의 경관조형물을 대상으로 현지조사를 통해 직접 측정하여 검증하였다. 본 연구에서는 재료성능, 구조안전성능, 내구성능, 경관성능 등 자연형 경관석 GFRC의 재료 및 시공 후 평가 가능한 항목에 대한 성능기준을 제안하였으나, 추후 시공사례지에 대한 지속적인 모니터링을 통해 최근에 대두되고 있는 친환경적이고, 생태적인 성능기준에 관한 후속 연구가 필요하다. This study aims to establish the performance standard for natural type landscape stone GFRC. The required performance such as material performance, structural safety performance, durability performance, and landscape performance were selected through an examination of domestic and overseas performance related references and examples, and through the questionnaires obtained from 40 experts, and the verified items and performance standards were proposed. Among the required performances, the material performance(glass fiber content, air-dried gravity), structural safety performance(flexural strength, compressive strength), durability performance(crack, corrosion resistance), and landscape performance(texture, efflorescence) were selected through the questionnaires obtained from the experts. In the case of material performance and structural safety performance with the corresponding standards that existed, final performance evaluation standard was proposed by conducting a test and comparing it with the existing standard sample, and in the case of durability performance and landscape performance on which standard does not existed, they were verified by measuring directly through field examination of formative landscape items such as artificial waterfall etc. In this study, performance standard for the material on natural type landscaping rocks GFRC and items which can be evaluated after construction such as material performance, structural safety performance, durability performance, landscape performance, and so forth were proposed, however, follow up study for pro-environmental and ecological performance standard which were recently gaining force would be required through a continuous monitoring for the construction samples afterwards.
