INCORPORATION OF V, ZN AND PB INTO THE CRYSTALLINE PHASES OF PORTLAND CLINKER

摘要: Burning of industrial wastes in cement kilns has an increasing environmental importance, brought about by the incorporation potentially hazardous elements into clinker crystalline phases and partial substitution primary fuel raw materials. In this study, experimental clinkers were synthesized, with addition V, Zn Pb to a standard meal, from which control was obtained for comparison. The three metals chosen as they are present alternative petcoke (V) (Zn, Pb) commonly burned kilns. Electron microprobe scanning electron microscope analysis revealed preferential partition these among phases. It observed that V shown towards C2S. appears higher amounts periclase, C3S contents than concentrates minute spherules partitions toward small amounts.
