Abstract

Both rapid industrial development and society has achieved more comfortable life. But, behind this facts of this industrial development have current pictures that occur global warming and much more by-products by environmental pollution. Therefore, this study used BFS and CFA as by-products to reduce cement usage emitted at a high rate of $CO_2$ gas, to examine sludge recycling strategy more than 200,000ton emitted at local dyeing complex, we suggest basic data research about non-cement matrix properties of utilizing dyeing sludge carbide. As a result, the more dyeing sludge carbide replacement ratio gets higher, the more air content and flow rise. Also, as the dyeing sludge carbide replacement ratio increase more, flexural strength and compressive strength go down.

산업의 급격한 발달과 함께 사회 또한 급격한 발달을 이루면서 전 세계는 편리한 생활을 이룰 수 있게 되었다. 하지만 이러한 산업의 발달의 이면에는 환경오염으로 인한 지구온난화와 산업부산물 대량 발생 등의 문제가 발생하고 있는 실정이다. 이에 본 연구는 건축분야에서 $CO_2$ 배출 비율이 높은 시멘트의 사용량을 줄이고자 산업부산물인 고로슬래그와 순환 유동층 연소 플라이애시를 사용하였으며, 국내 염색공단에서 배출되고 있는 20만 톤 이상의 슬러지를 재활용하는 방안을 검토하기 위해 염색슬러지 탄화물을 활용한 무시멘트 경화체의 특성에 대한 기초자료를 제시하고자 하였다. 그 결과, 염색슬러지 탄화물의 치환율이 증가함에 따라 공기량은 증가하였고 플로어는 증가하였다. 또한 염색슬러지 탄화물 치환율이 증가함에 따라 휨강도 및 압축강도는 감소하는 경향을 보였다.
