A Study on the Effects of Concrete Mixing Properties on Chloride Diffusion Coefficients

콘크리트의 배합특성이 염화물 확산계수에 미치는 영향에 관한 연구

Chloride ions are considered to be the major cause of steel corrosion in concrete structures exposed to seashore environments. Thus, estimating chloride ion concentrations by ages is needed to predict service life of seashore structures. Experimentally measured chloride profiles were used in this study for estimating chloride diffusion coefficients, and a relationship between mixing properties and chloride diffusion coefficients is proposed for predicting chloride penetrations.
