Abstract

Raw mix of molten clinker was fabricated using blast furnace slag as starting material. Raw mix was melted at 1620 for molten clinker fabrication. Color and mineral composition of molten clinker was investigated by XRD and colorimeter. It was found that the molten clinker contains alite and belite equivalent to OPC clinker mineral and shows higher whiteness value than that of OPC. Whiteness of the molten clinker decreased with LSF and SM. Also the whiteness value of the slag cement using molten clinker was higher than that of common slag cement.

용융클링커 제조용 혼합원료 중의 하나로 고로슬래그를 사용하였다. 고로슬래그를 사용한 혼합원료는 용융클링커 제조를 위해 1620에서 용융하였다. 냉각된 클링커는 XRD 패턴으로 클링커 광물의 생성여부를, 색도분석기로 색도를 분석하였다. 용융클링커는 XRD 분석을 통해 OPC 광물과 동등의 클링커 광물을 포함하고 있다는 것을 확인할 수 있었다. 용융시멘트는 OPC보다 백색도가 높아, 색상이 OPC보다 옅게 관찰되었다. 용융시멘트의 LSF 및 SM이 높아짐에 따라 백색도는 낮아졌다. 또한 슬래그를 용융시켜 제조한 시멘트 클링커는 고로 슬래그시멘트보다 백색도가 높았다.
