Abstract
This study was performed to examine the freezing and thawing properties of the high strength concrete using recycled coarse aggregate. The recycled coarse aggregate was replaced by 0%, 25%, 50%, 75% and 100% of natural crushed aggregate. The compressive strength of the concrete used recycled coarse aggregate was shown in more than
이 연구는 플라이 애시를 결합재 중량의 20%, 재생굵은골재를 천연쇄석굵은골재의 0%, 25%, 50%, 75%, 100%를 치환하여 압축강도와 동결융해 특성을 구명하였으며, 이 연구를 통해 얻어진 결과를 요약하면 다음과 같다. 1. 재령 28일의 압축강도는 모든 배합비와 W/B 35%에서
