説明

A new inspection technique that uses near-infrared spectroscopy is focused on as a method for detecting the chloride ion content in concrete structures. The authors have been working to confirm the possibility of estimating comparatively easily the chloride content in concrete without chemical analysis and in a short time on site. In this study, mortar specimens deteriorated by the combination of chloride attack and carbonation were prepared for investigating the method of evaluating the chloride ion content in mortar with the near-infrared spectroscopic technique. As a result, it was found that the chloride ion content in a carbonated mortar specimen can be evaluated with a method similar to that used to detect deterioration due solely to chloride attack.
