The Estimation of Steel Corrosion in Concrete Specimen Exposed under Seawater

해수에 방치한 콘크리트 시험체 중의 철근 부식 추정

This study was performed for the purpose of obtaining the fundamental data to establish the criterion of concrete deterioration and presuming steel corrosion of concrete structures under the environment of seawater. It was exposed in seawater for 1 year that steel was embedded in the concrete specimen. The diffusion coefficients of concrete, corrosion potential and steel corrosion were considered. The results show that corrosion potential is reduced according to steel corrosion and corrosion area ratio is correlative with diffusion coefficients of concrete.
