Microwave clinkering of ordinary and colored Portland cements

Fang, Y. / Roy, D.M. / Roy, R.

Regular and colored cement clinkers were prepared by microwave processing at 2.45 GHz. Microwave enhancement in clinker reaction was observed. The preliminary results show that microwave processing can lower the clinkering temperature by about 100 deg C compared to the samples processed in a fast-heating electric furnace. The microwave enhancement was manifested by the lowered clinkering temperature. The iron oxide in the ordinary cement raw meal and amorphous silica in the white cement samples are believed to be responsible for the microwave enhancing effects.
