유기계 및 무기계 방청제의 포화수산화칼슘 수용액 내에서의 방식성능 평가

Abstract

In this study, in order to comprehend performance of corrosion inhibitor, the experiment study was conducted about corrosion characteristic 3 steps(0.0, 0.6, 1.2) of Chloride by added amount of inorganic(Ca(NO2)2) and organic(DMEA) corrosion inhibitor by the corrosion inhibitor types about 0.6kg/m3 , 2.4kg/m3 based on Chloride ion content 1.2kg/m3 for service life prediction of concrete structure by using Poteniostat. As a results, the excellent anti-corrosive performance of organic corrosion inhibitor was seen that absorption types organic corrosion inhibitor has excellent anti-corrosive performance compared to the inorganic nitrous acid corrosion inhibitor by the added amount of corrosion inhibitor.
