초록
부식면적에 기준으로 살펴보면, 염화물이온 함유량이 증가할수록, 재령이 증가할수록 부식면적이 증가하는 것으로 나타났다. 특히 염화물이온 함유량이
It is found that as contents of chloride ion and age increase, area of corrosion also increases. Inare increased to 1035 days from 730 days, slope of increase of corrosion area is greatest. Non-rust inhibitor specimens show corrosion area of 8~35 times more than rust inhibitor specimens and anticorrosive effects by application of rust inhibitor can be confirmed. When chloride ion is not contained, corrosion control effects of steel reinforcing according to increase of thickness are found, but specimens having chloride ion show no regular tend of thickness and corrosion due to complex problems such as reverse diffusion of chloride and test errors.
