摘 要：<正>In this paper,the cement clinkers fromvarious industrial kilns were investigated by a superposingpeaks method for X-ray quantitative analysis（XRQA）ofclinker minerals,the results show that the clinker mineralcontents measured by XRQA method better accord with thereality of clinkers made in different conditions than theo-retic contents calculated by Bouge formula do.The mea-sured contents of C3S of clinkers manufactured in rotarykilns are higher than theoretically calculated values,where-as,the results of clinker manufactured in shaft kilns arecontrary to that.This is because in rotary kiln,the rawmeals are fully pre-heated and have high sintering temper-ature,the clinkers are well solid-solutioned and rapidlycooled,on the contrary,owing to the struetural defects,it iseasy to exist reduing atmosphere and lower temperature inshaft kiln,moreover the cooling rate is slower,all these canevidently lead to worse clinker quality.Adding CaF2-Ca-SO4 complex mineralizer can remarkably modify the sinter-ing situat
