- Abstract
- 본 연구에서는 콘크리트 중 철근부식의 보수를 위해 전기방식법을 적용하여 부식복원 및 구조거동을 효과적이고 정량적으로 평가하였다. 부식상태는 8주간의 전기방식 이후에도 6.5 mA/m2의 부식 전류 및 330 mV (vs. SCE)의 부식전위를 나타내 여전히 부식이 존재함을 확인하였다. 구조거동에 있어 부식의 증가로 인해 콘크리트의 최대하중은 증가하였으나, 전기방식을 적용 이후 최대하중은 감소하였다.
The present study concerns quantitative assessment of steel co rrosion recovery and flexural behavior of concrete. Even after the treatment, the corrosion w as still active; the corrosion rate was 6.5mA/m2 and 330 mV vs. SCE in the potential. For structura l behavior, the maximum load was increased by corrosion on the steel bars, which was subsequently lowered by the treatment, but still higher than for control.
