DIAGNOSIS METHOD OF CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide a diagnosis method of concrete capable of removing an influence of the first deteriorated component, and detecting accurately the second deteriorated component.

SOLUTION: This concrete diagnosis method for detecting a deteriorated component by performing spectroscopic analysis of reflected light of a near infrared ray irradiated to a concrete surface, is characterized by having: the first process for collecting a plurality of absorption spectrums; the second process for removing the influence of the first deteriorated component from the absorption spectrums collected in the first process; and the third process for detecting the second deteriorated component by applying a statistical procedure to the absorption spectrums from which the influence of the factor is removed.
