Abstract

Bamboo is representing environmentally friendly building finishing materials as proven in the former researches. The purpose of this study is to evaluate the application properties of cementitious materials modified with bamboo charcoal as building finish materials. Flow test in fresh condition was conducted to assess the workability. Compressive and bending strength were measured after harding. As the thermal properties, thermal conductivity and density were measured. The properties were surpassing over them in case of using the pine charcoal in every tests. The thermal conductivity of them increased with the modified ratio. After the modified ratio 50%, the thermal conductivity decreased. Insolation and absorption performance is due to the lower density by modification of bamboo charcoal.

활성탄을 혼입한 모르타르의 특성을 분석한 결과 유동성 측면에서는 무치환과 참나무 숯 모두 큰 차이를 보이지 않았고, 강도적인 측면에서는 활성탄을 혼입한 모르타르의 강도가 참나무 숯과 무치환 모르타르에 비해 높게 나타났다. 열적 특성은 치환율이 증가할수록 두 혼화재 모두열전도율이 감소하는 경향을 보여 단열성능이 우수함을 입증하였다. 결과적으로 활성탄을 혼입한 모르타르가 강도와 단열성능이 우수함을 증명하여 기존의 활성탄이 가지고 있는 오염물질 흡착성능과 함께 우수한 건축 마감재로서의 여러 성능이 검증되었다.
