dc.description.abstract본 논문은 콘크리트 배합 방식(NMA, TSMA1, TSMA2)에 따른 순환 굵은골재 치환량에 따른 콘크리트의 기계적 성능을 비교 평가하였다. 실험은 순환 굵은골재를 0%, 50%, 100%로 3수준으로 콘크리트의 배합 방식에 따라 실험을 진행하였다. 굳지 않은 콘크리트에서는 공기량, 슬럼프, 단위용적질량 실험을 진행하였으며, 경화 콘크리트에서는 압축강도 및 휨강도 시험을 진행하였다. 본 연구의 실험결과 NMA 방식과 비교하여 TSMA 방식에서 강도 저하가 나타나고 있음을 확인할 수 있었다. 하지만, 이는 순환 굵은골재가 다량 치환됨에 따른 것으로 사료된다. 순환 굵은골재가 다량 치환됨에 따라 슬럼프 증진, 공기량 증진, 강도 저하가 나타남을 확인하였다.-
dc.description.abstractAs the lack of specific aggregation intensifies, the development of alternative resources is urgent. Construction waste is increasing every year, but recycled aggregate is used as a low value added material. Various studies are currently underway at the national level. In this paper, the mechanical performance of the concrete according to the concrete mixing method and the replacement amount of the circulating coarse aggregate was compared and evaluated. Concrete mixing method was normal mixing approach(NMA) method, two-stage mixing approach1 (TSMA1) method, two-stage mixing approach2 (TSMA2) method. Fresh concrete was tested for air content, slump test, and unit volume weight. Compressive strength and flexural strength were tested in hardened concrete. According to the TSMA method, the mechanical performance difference of concrete is shown, and the strength is decreased according to the circulating coarse aggregate replacement amount.-
