Abstract

The characteristic analysis of cement clinker using light microscope can evaluate not only the quality of cement but also making process. Thus this study analyzed clinkers having different burning conditions by reflective light microscope. As heating and cooling rates is decreased, alite and belite minerals grew and especially cooling rate had an effect on the growth of belite. Futhermore as the retention time in max. temperature got longer by twenty minutes, alite and belite minerals grew more about 5 $\mu\textrm{m}$. In the case of temperature 1400$^{\circ}C$ in max, the size of belite was suitable but alite was not suitable with the size of 10～15 $\mu\textrm{m}$.

광학 현미경을 사용한 시멘트 클링커의 특성 분석은 시멘트의 품질뿐만 아니라 제조공정도 예측 평가할 수 있다. 그러므로 본 연구에서는 광학 현미경(반사)으로 소성 조건을 달리한 클링커의 특성을 분석하였다. 승온 및 냉각 속도가 느려짐에 따라 alite와 belite는 성장하였으며, 특히 냉각 속도는 belite의 성장에 큰 영향을 주었다. 또한 최대 소성 온도에서의 유지 시간이 20분 증가함에 따라 alite와 belite가 약 5fm정도 성장하는 것을 확인하였으며, 최대 소성 온도가 140$0^{\circ}C$인 경우, belite의 크기는 양호하나 alite는 제대로 성장하지 않은 10～15$\mu\textrm{m}$수준이었다.
