A Study on the Evaluation of the Corrosive Environment of Reinforcement Bar by Concrete Layer Resistivity

콘크리트 층간비저항에 의한 철근의 부식환경 평가에 관한 연구

Deterioration factors such as CO₂ and chloride ions cause steel corrosion in RC structures. The diffusion of these factors depends on the water content in concrete. To examine the moisture condition of concrete, this research considers the availability of the steel effect ratio, which is calculated by Resistivity Estimation Model (REM). It is concluded that the steel effect ratio is expected to be available as a quantitative evaluation method in the assessment of concrete layer resistivity.
