| ABSTRACT |
|
With the increase of ZnO content, burnability of raw materials was improved and the formation of clinker minerals was accellerated. When ZnO was added 1wt%, the clinkering temperature was decreased about 30~5$0^{circ}C$. As an increase of ZnO added, aluminate phase was decreased and ferrite phase was increased. When ZnO was added more than 3.0wt.%, the new phases, such as ZnO.Al2O3 and ZnO.Fe2O3 were formed. In the excess of amount of ZnO added, the decomposition of alite phase was intensed and the lamella structure in belite could not be observed due to the decomposition. |
