低品質再生骨材を用いたコンクリートの性能評価および調合設計

Abstract

This study aims to promote the use of recycled aggregate concrete that can be easily manufactured in Vietnam using low-quality recycled aggregate mixed with normal aggregate. This is achieved by examining performance evaluation of concrete through the relative quality index method and mix proportion design. If low-quality recycled aggregate and normal aggregate can be combined in concrete in a suitable replacement ratio, as has been done in Japan, the proposed method can be used for structural concrete applications in Vietnam.
