Abstract |
Concrete structures move wholly with concrete and rebar, so they endure external force, but recently the embedded rebar in concrete has been corroded by environmental, physical and chemical factors. the embedded rebar corrosion influences concrete structures to deteriorate structural capacity.??And also, the rebar corrosion causes??crack of concrete, separation of covering concrete by expansion pressure due to the rebar corrosion and decrease of steel section. 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. |
