<p><P>PROBLEM TO BE SOLVED: To provide a diagnostic method for concrete for diagnosing the degradation of the concrete while removing an affection of an affection factor, when optically detecting the degradation of the concrete surface. <P>SOLUTION: In the diagnostic method for the degradation of the concrete by spectroscopically analyzing the reflection light while irradiating the concrete surface with a near IR beam, a salt damage factor, neutralization factor, alkali-aggregate reaction factor, or sulfate corrosion factor etc. are detected from the obtained absorption spectrum using the chemometric means. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
