요 약 염소 바이패스 분진의 주성분은 칼슘, 알칼리 및 염소 성분이며, 시멘트 원료로 재활용하기 위하여 염소 성분 제거가 필요하다

The cement industry emits a large amount of GHGs (greenhouse gases) and about 65% of GHGs is originated from limestone. So non-carbonated CaO materials were examined to replace limestone in this study. It was attempt to replace limestone by used blast furnace slag, converter slag, and KR slag with high CaO content. For manufacture clinker, LSF, SM, and IM were controlled at 92, 2.5, and 1.6, respectively, and the CaCO 3 replacement rate was fixed at 3%, 6%, 9%, and 12%. As using blast furnace slag, the CaCO 3 replacement rate was possible up to 12%, but for converter slag and KR slag, up to 3% and 9% were possible. The burnability of clinker was better when blast furnace slag and KR slag were used. The XRD peak intensity of clinker used blast furnace slag gradually decreased as the amount of slag used increased, but when KR slag was used, the XRD peak intensity actually increased. It was presumed to be because KR slag has a high CaO content and already contains C2S, making it easier to produce clinker minerals.

요 약 시멘트 산업은 다양한 산업부산물을 시멘트 클링커용 원료 및 연료로 사용하고 있다. 이들 산업부산물은 대부분 염소를 함유하여 클 링커 물성에 다양한 영향을 줄 수 있다. 따라서 본 연구에서는 염소 함량을 제어한 클링커의 광물학적 특성, 특히 알라이트 및
