초록

최근 들어 환경보호나 국토의 효율적 활용 등의 측면에서 산업 각 분야에서 발생되는 각종의 산업부산물 및 폐기물 등의 유효하 고 효율적인 이용이 대두되고 있다. 본 연구에서는 갈수록 발생량이 증가하는 하수슬러지를 활용한 하수슬러지 소각재의 유효한 활용을 위하여 건설재료로서의 가능성을 평가하였다. 콘크리트 제작 후 평가항목은 압축강도, 중성화저항성 및 환경 평가인 용출시험으로 압축강도 및 중성화저항성에서 무첨가 콘크리트에 비해 만족스런 결과를 도출하였으며 용출시험 결과 역시 기준치를 모두 만족하는 결과를 나타냈다. 따라서 콘크리트용 잔골재로서 활용 가능성이 충분하며 적정 대체율은 약 10% 정도로 판단된다.

In recent years, in terms of environmental protection and efficient use of the land, efficient utilization of byproducts and wastes generated in industrial areas are emerging. In this study, for the effective utilization of using ever increasing amount of utilizing sewage sludge incineration ash to increase sewage sludge, it is evaluated the use of as an construction material. After making concrete specimens, it is evaluated compressive strength, carbonation and environmental resistance. From the experimental results, compared with concrete without sewage sludge it is obtained satisfactory results for compressive strength and carbonation and results of the leaching test also satisfies the standard value. So, it is sufficient possibility using of concrete aggregate and the replacement rates is judged to be about 10%.
