플라이애쉬를 혼입한 에코시멘트 콘크리트 보의 휨 성능에 관한 실험적 연구

Abstract

The construction industry of Japan developed the eco-cement using city garbage, sewage and others for the domestic waste disposal, and this cement was adopted in JIS R 5214. However, there is the problem that the compressive strength of the concrete using the eco-cement under the long term age is lower than the concrete using portland cement. Accordingly, in the previous study, the compressive strength properties of eco-cement concrete using the fly-ash under the long term age was investigated, and almost the same properties were shown between the portland cement concrete and eco-cement concrete mixing fly ash. In this study, bending test was conducted to investigate the flexural performance of eco-cement concrete beam mixing fly-ash, and almost same structural performance was investigated between the portland cement concrete specimen and eco-cement concrete mixing fly ash specimen.
