Abstract
<p> Countermeasures against deterioration of port facilities in Japan are urgently required. It is necessary to catch signs of deterioration and to take preventive measures before the facilities are deteriorated. Therefore, a low cost, simple and highly reliable inspection system for predicting deterioration is needed. Since mooring facilities in ports are greatly affected by salt, in the case of concrete structures, it is effective to collect information on the chloride ion concentration on the surface of the structure in order to accurately grasp the sign of this deterioration. In this research, we report the contents of verifying the performance of equipment by developing non-destructive, non-contact, compact, portable and high-performance equipment based on near infrared spectroscopy. Moreover, it confirmed that two-dimensional imaging in the chloride ion concentration of the specimen cross section could be performed in a short time and with high accuracy. We also conducted outdoor measurements and confirmed that two-dimensional imaging of chloride ion concentration is possible almost accurately.</p>
