Abstract

The influence of water to cement ratio on the corrosion mechanism of steel bars embedded near a bending crack was experimentally investigated. First, early corrosion tests were syudied using mortar. Chloride ion and oxygen permeations were investigated, considering the gap between steel and concrete. The influences of those permeations on macrocell corrosion were studied. Lastly, tests on concrete specimens were conducted to confirm the results obtained from the mortar cese. Results show that the permeation near the bending crack plays a important role in corrosion behavior.
