Effect of the Rebar Corrosion Rate on Bond Strength in Reinforced Concrete - Factors caused by compressive strength and embedded rebar condition -

철근의 부식도가 콘크리트의 부착강도에 미치는 영향 - 콘크리트 강도와 철근매입 조건을 인자로 하여 -

The social trouble to the durability of concrete rises recently because the embedded rebar corrosion influences concrete structures to deteriorate structural capacity. And also, the rebar corrosion causes crack of concrete, decrease of steel section and separation of covering concrete. In the result, the bond strength of concrete and embedded rebar decreases, which causes deterioration of the structure behavior in reinforced concrete. In this study, the relation of bond strength and bond-slip was understood to evaluate capacity deterioration of reinforced concrete, and experiments were carried out by compressive strength and embedded rebar condition in the rebar corrosion rate.
