Effect of Rebar Corrosion on the Onset of Cracks in Cover Concrete

철근부식에 의한 콘크리트의 균열발생에 관한 연구

This study was carried out to quantitatively investigate the amount of corrosion at the time of onset of cracks in cover concrete due to rebar corrosion. In this experiments, the accelerated galvanostatic corrosion method was carried out. FEM analyses were also conducted to investigate the expansive behaviors due to rebar corrosion and the mechanical properties of corrosion products. As a result, it was concluded that the corrosion ratio at the time of onset of cracks in cover concrete was 3% by weight. The onset of cracks in cover concrete due to rebar corrosion could be analyzed by the finite element method.
