Evaluation on Chloride Diffusion Coefficient of Mortar with Recycled Fine Aggregate

순환잔골재를 사용한 모르타르의 염화물확산계수 평가

Mechanical properties and durability of recycled aggregate concrete was known to decrease due to the adhesive mortar of recycled aggregate. But in this study, As the result of chloride diffusion resistance of recycled fine aggregate mortar, the mechanical properties are reduced according to the increase of the substitute ratio of recycled fine aggregate. But the chloride diffusion coefficient was almost same with natural fine aggregate mortar.
