Mineralogy and SEM study of Reducting conditions in the Khoy cement factory clinkers, NW Iran

In this research to study the mineralogical aspect of reducting conditions in the Khoy cement factory clinkers, West Azarbaijan, NW Iran, five polished sections were prepared and were studied in economic geology laboratory in the university of Tabriz, also SEM pictures from the brown core coarse clinkers were prepared in the research center of basic science in the university of Tabriz with Electron Microscope type MIRA3 FEG-SEM. The results show that large size clinkers have a brown core due to reduce oxygen and creation reducting conditions in the kiln. In This clinkers Alite phases are unstable and alteration to another phases but small size clinkers do not show any brown core also SEM pictures conform the reducting conditions in the coarse clinkers.
