这是近红外光谱分析混凝土表面氯离子的无损非接触检测设备的基础性研究。对氯离子进入混凝土产生的弗里德尔盐进行了无损测量；利用每种物质特有的特征吸收进行定性和定量分析。然而，将Friedel盐的吸收峰与其他水合物的吸收峰分离一直是一个困难。研究了用贝叶斯定理提取Friedel盐的吸收峰进行定量评价的方法，并用一些常规方法验证了该方法的有效性。
This is a fundamental study of a non-destructive and contactless equipment to evaluate the chloride ion on concrete, with near infrared spectroscopy. Non-destructive measurements on Friedel’s salt, generated by ingress of chloride ion into concrete, have been studied; characteristic absorption unique to each substance was utilized to qualitative and quantitative analyses. However, there has been a difficulty in separating absorption peak of Friedel’ salt from that of other hydrates. This study investigates the method to extract the absorption peak of Friedel’s salt by Bayes’ theorem for quantitative evaluation, and its validity was confirmed using some conventional methods.
