A proposal for reliability improvement of non-destructive evaluation technology for concrete

Abstract

The subcommittee of the JSCE (Japan Society of Civil Engineers) concrete committee for the improvement of the reliability of non-destructive evaluation technology for concrete chaired by Professor Toshiro Kamada of Osaka University (Committee 339 below) has discussed measures for the improvement of the reliability of non-destructive evaluation technology from two perspectives: education, and standards and specifications. This paper describes the roles that standards and specifications play in terms of improving the reliability of these technologies. Moreover, a pattern of reliability based on the client-engineer correlation is identified. As a result, it was found that the reliability of non-destructive evaluation can be enhanced to some extent by identifying the scope of application and standardizing the method of non-destructive testing. For ultimate improvement of reliability, the pattern of reliability itself should be changed through technical innovation for non-destructive testing or the enlightenment of the client. © RILEM 2013.
