Abstract

This study investigated the use of recycled aggregate from waste asphalt concrete in dry soil concrete mixed with red mud. The results showed that dry soil concrete utilizing waste asphalt recycled aggregate had relatively lower compressive strength compared to that using crushed aggregate. However, dry soil concrete mixed with red mud using waste asphalt recycled aggregate achieved a compressive strength of over 18.0MPa, meeting the highest performance standard for parking lot use, when the cement content was more than 250kg/m3.

본 연구에서는 폐아스콘 순환골재의 용도확대를 위한 연구로서 물-시멘트 비 및 시멘트량에 따른 폐아스콘 순환골재를 활용한 레드머드 혼입 건식 흙콘크리트의 강도발현 특성을 부순골재와 비교 검토하고자 하였다. 그 결과, 폐아스콘 순환골재를 활용한 건식 흙콘크리트는 부순골재를 사용한 흙콘크리트와 비교하여 압축강도는 상대적으로 낮았고, 시멘트량에 대한 영향은 큰 것으로 나타났다. 폐아스콘 순환골재를 활용한 레드머드 혼입 건식 흙콘크리트는 시멘트량 250kg/m3 이상의 배합에서 흙콘크리트 단체표준규격 중 가장 높은 성능인 주차장용 압축강도 18.0MPa 이상을 만족하는 것으로 나타났다.
