Effect of microwave processing on aluminate cement clinkering

Abstract

When raw materials were preheated to 1000–1300°C by electricity and microwave was inputted for 1 min 5 s-4 mins, then alunminate clinkers were obtained. The f-CaO contents, XRD patterns and lithofacies analysis show that the microwave processing accelerates the clinkering reaction, and Fe₂O₃ is contributed to the aluminate cement clinkering. The appearance of liquid phase in process of microwave heating increases the microwave absorbability of materials greatly.
