电子探针(EPMA)目前已经用来定量评价氯离子在水泥基材料中的侵入。为了进一步了解EPMA的功能以及应用EPMA研究材料的性能,本文阐述了EPMA的演变,工作原理及主要的分析方法,并总结了EPMA在测量水泥基材料中的有害离子、多元素分析以及氯离子浓度曲线等方面的相关应用。
The electron probe micro-analyzer (EPMA) has been used for the quantitative evaluation of Cl in- gression into cement-based materials. In order to further understand the function of the EPMA and study the properties of the materials by using the EPMA,the EPMA development,working principle and the main analytical method were described in this paper. In addition, the applications of EPMA in the measurement of harmful ion, muhi-element anal- ysis and chloride ion concentration curve of cement-based materials were summarized.
