Abstract
Using pure chemical reagents and varying the MoO3 content (0-3.0w/w %) two series of eleven compositions, each for C3S and C(3)A phases, wer e prepared at 1450 degrees C and investigated in respect of the molybd enum effect on the phases formed. Results derived by X-Ray Diffraction (XRD) and step by step XRD scanning technique reveal that MoO3 additi on, within the range examined, promotes both C3S and C(3)A formation. In both cases MoO3 causes a remarkable increase of the crystal size. H igher than 1.O(w/w)% MoO3 addition favours the formation of the monocl inic form of the C3S phase. (C) 1997 Elsevier Science Ltd.
