Abstract
Corrosion of steel reinforcement usually causes damage and deterioration of the reinforced concrete. Conventional corrosion experiments or analysis typically focus on the overall corrosion of the entire reinforcing steel bar while the distribution of the corrosion along the rebar has not yet been extensively investigated. In the present study the distribution of corrosive damage was investigated in a series of controlled, accelerated corrosion tests. The acoustic emission (AE) technique was employed to correlate the acoustic emission characteristics to the corrosion along the corroded rebar. A model for the corrosion damage distribution is established based on a Gaussian distribution function. The numerical modeling results match reasonably well with experimental results in almost all corrosion tests.
