摘要
采用平行对比试验方法,借助高温显微镜(HTM)、差热分析(DTA)、X射线衍射(XRD)和化学分析等测试手段和分析方法,对比研究了加与未加晶种硅酸盐水泥熟料的形成过程。结果表明,添加晶种对硅酸盐水泥熟料的形成具有显著的促进作用。加与不加晶种相比,碳酸盐大量分解、一期固相反应、二期固相反应、C3S形成等温度分别提前约10,20,30,40℃;达到同一煅烧程度时加晶种比不加晶种试样在高温下停留时间可缩短5~10min。
The reference tests method are carried out parallelly,by means of high-temperature light microscope(HTM),differential thermal analysis(DTA),X-ray diffraction(XRD)and chemical analysis to study the formation of portland cement clinker added with and without crystal seed.The results show that the crystal seed added to raw meals promotes the formation of portland cement clinker.During calcining raw meals with crystal seed,the temperatures of decomposing large amount of carbonate of lime,first stage and second stage of solid phase reactions and formation of C3S decrease 10,20,30,40℃ respectively compared with that without crystal seed.And at the same calcining level,the staying time of raw meals at high temperature shortens 5~10 minutes.
