摘　　要：采用化学分析、ＸＲＤ、光学显微镜分析等方法，较系统地研究了Ｒ２Ｏ、Ｒ２ＳＯ４对硅酸盐水泥熟料烧成、矿物组成、晶体结构的影响。结果表明：Ｒ２Ｏ易形成固溶体ＫＣ２３Ｓ１２和ＮＣ８Ａ３，其中Ｋ２Ｏ主要固溶在Ｃ２Ｓ中，形成ＫＣ２３Ｓ１２，使ｆＣａＯ急剧升高；Ｎａ２Ｏ主要固溶在Ｃ３Ａ中，形成ＮＣ８Ａ３，ｆＣａＯ有所增加。Ｒ２ＳＯ４降低了熟料烧成的液相粘度，对熟料烧成有利，ｆＣａＯ含量很低。Ｒ２Ｏ和Ｒ２ＳＯ４都使Ａ矿含量降低，晶体尺寸增大。The influence of R 2O,R 2SO 4 on clinker sintering, the mincral composition and crystal structure was studied by chemical analysis XRD and optical microscope.The results show that KC 23 S 12 and NC 8A 3 can be formed easily on R 2O conditions.K 2O solves into C 2S mainly to form KC 23 S 12 to result in a much increase of f CaO , Na 2O solves into C 3A mainly to form NC 8A 3 to result in a slight increase of f CaO .R 2SO 4 result in the decrease of liquid viscosity and clinker sintering easily and lower content of f CaO .Both R 2O and R 2SO 4 can result in the decrease of C 3S and increase of the size of alite.
