초록

본 연구는 석회석, 셰일, 전로슬래그, 플라이 애쉬를 사용한 혼합원료에 대해 보통 포틀랜드 시멘트 원료로서 하수슬러지 소각재의 사용에 대해 조사하였다. 이와 관련하여 원료 중 셰일에 대한 하수슬러지의 적정 치환 비율을 확인하였으며, 1,300, 1,350, 1,400, 1,450, 1,50$0^{\circ}C$에서 1시간 혼합원료를 소성하였다. 이후 공기중 급냉을 시행하였으며, XRD, SEM을 통하여 합성된 클링커의 특성을 평가하였다. 또한, 클링커의 미반응 산화칼슘을 측정하여 소성성에 대한 결과를 얻었다.

This study has been carried out to use the municipal solid waste sewage sludge ash generated at sewage disposal field as the raw materials of Ordinary Portland Cement (OPC). Limestone, shale, converter slag, and fly ash were used as the main raw materials. After the raw materials were mixed, these were fired at 1,300, 1,350, 1,400, 1,450, and 1,500$^{\circ}C$ for 1 h and cooled rapidly in air. The properties of clinker synthesized were examined with XRD, SEM, and burnability index by polysius method.
