| Abstract: | In order to explore the influence of calcination temperature on the mineral phase of cement clinker, the clinker was analyzed qualitatively, quantitatively and morphologically by XRD, Rietveld and lithofacies method. The results show that Rietveld method can be used to measure the relative content of each mineral phase in the clinker quickly and accurately. According to the content of mineral phase calculated by Rietveld method, it can be seen that calcination temperature has a direct effect on the content of mineral phase in the clinker, especialy C3S and C2S. The results of mineral phase content obtained by Rietveld method are close to those obtained by Bague algorithm, but the content of C3A obtained by fitting is lower. This is due to the rapid cooling of clinker which makes C3A exist as glass phase. With the increase of calcination temperature, the crystal nucleation and development are more perfect, and the clinker shows better morphology. |
