Abstract：Due to the differences of coal ash subsidence and internal and external firing temperatures of clinker particle in rotary kilns, the mineral phase composition of the outer, middle and inner layer of the large particle clinker is different, resulting in the different strengths of the cement clinker. By means of chemical analysis, XRD quantitative analysis and SEM morphology analysis, the differences of chemical composition, mineral composition and crystal structure of the outer, middle and inner layers of the same large particle cement clinker with diameter of about 40 mm were studied. The results showed that SiO2 content and C3S content decreased gradually from outer layer to inner layer. Meanwhile, the content of C2S that did not react with f-CaO increased, while the overall content of silicate minerals decreased. From the outer layer to the inner layer, the C3S-M1 type gradually transformed into the C3S-M3 type and the C3S-T type.
