摘　　要：利用X射线衍射结合Rietveld方法等,研究在Na+、K+等工业熟料中常见的固溶组分的作用下,Ca F2掺杂对阿利特结构、水化活性的影响。结果表明:Ca F2掺杂不改变阿利特晶型,其主要稳定为M3型,但其晶格常数会因Ca F2的掺入而变化,变化规律符合Vegard固溶体定律;F-掺杂可以改变阿利特的水化活性,使得早期水化放热峰以降低为主。The effect of CaF_2-doping on the crystal structure and hydration activity behavior of Alite with some common impurities in cement clinker like Na^+,K^+ etc.was studied by means of X-ray diffraction with the Rietveld method.Results indicated that the CaF_2-doping Alite was mainly in stabilized M3-type,and the lattice parameters of M3 polymorph will be changed with increasing of CaF_2-doping,which followed by the Vegard's law.CaF_2-doping could change the hydration activity of Alite,which would lead the early hydration exothermic peak to be decreased.
