Abstract
Provided are a method of semi-quantitatively evaluating concrete carbonation including the steps of a specimen preparing step of preparing a concrete specimen for identifying a degree of carbonation, a carbonation depth measuring step of measuring a carbonation depth of the specimen by a method of promoting carbonation of the specimen using a carbonation promoting tester and applying an indicator, an X-ray diffraction (XRD) analyzing step of qualitatively analyzing components of the specimen by an XRD method after cutting the specimen from a top end to a predetermined depth and crushing the specimen. Thus, the method of the present invention may calculate the exposure time of concrete carbonation by converting the analysis result value of XRD to the result value of TG-DTA.
