Abstract

In this study, as a result of eva lua ting the quality properties of Living Concrete, the flow of the table showed a tendency to decrease as the mixing ratio of ocher increased. Compressive strength was found to decrease with increasing loess mixing ratio. Density properties were evaluated for weight reduction, As a result of comparison with the panel using cement as a comparison group, the density was measured to be a bout 20 % lower than that of the cement panel, and it is judged that it is less affected by the load and can be installed in the structure. As a result of evaluating the panel temperature reduction, there was a difference in the temperature reduction with time. It is judged that the panel planted with moss has a lower temperature than the panel without moss, so it is judged that it can be used in a vertical greening system.

본 연구에서는 Living Concrete의 품질특성 평가결과 유동성은 황토 혼합율 증가에 따라 테이블 플로우가 감소하는 경향이 나타났으며, 압축강도는 황토 혼합율 증가에 따라 감소하는 것으로 나타났다. 경량화를 위하여 밀도 특성 평가를 실시하였으며, 비교군으로 시멘트를 사용한 패널과 비교한 결과 시멘트 패널의 밀도에 비해 약 20 % 낮은 밀도가 측정되어 하중에 영향을 적게 받아 구조물에 설치가 가능할 것으로 판단된다. 패널온도 저감성을 평가한 결과 시간에 따른 온도 저감의 차이가 나타났으며, 이끼가 착근된 패널이 이끼가 착근되지 않은 패널보다 온도의 저감이 나타나 수직형 녹화시스템에 활용이 가능할 것으로 판단된다.
