Effect of MoO₃ on the Clinkers Formation of Portland Cement

Abstract:

The effects of MoO₃ additives on the clinkers mineral formation of portland cement were investigated by X-ray diffraction,scanning electron microscopy. One reference mixture and others modified mixtures, prepared by mixing the blank sample with chemical grade MoO₃ were studied. Based on experimental result, MoO₃shows the less positive effect, MoO₃ added less than 1wt% was benefit for f-CaO absorbtion, but when more than 1wt% MoO₃was added, with the temperature increasing, increasing the free CaO (f-CaO) content compared with the pure sample,which cound not promote the formation of 3CaO·SiO₄. MoO₃ can stabilizes crystalline structure of β-2CaO·SiO₄. The analysis results for the microstructure indicate that grain size of C₃S in the samples with MoO₃ is larger than that of only -portland clinker.
