摘要
简要论述了水泥中方镁石对安定性的影响,介绍了定量测定水泥中方镁石的主要方法,包括BT法、TK法、乙二醇法、电导法、X射线测定法等,探讨了这些方法的优缺点及可行性,并提出用回收率评价准确度的不合理性。
It is briefly discussed that periclase has influence on the stability of cement. Some methods of deterrnining periclase are introduced, such as BT method, TK method, ethylene glycol method, conductivity method, XRD method and so on. Meanwhile, the advantages and disadvantages of these methods are investigated and the feasibility of these methods is studied too. And it is unreasonable to evaluate the accuracy using recovery.
