Numerical simulation of non-uniform corrosion states in rebars under natural chloride environment

Corrosión of embedded rebars is a classical deterioration mechanism of reinforced concrete structures exposed to chloride environments. Macro-cell corrosion process involved in a typical chloride-induced corrosion of RC components exposed to natural chloride environment results in non-uniform corrosion states in rebars. In the present study, such nonuniform corrosión states around steel-concrete interfacs of rebars are captured by solving governing field equations through a combined finite element and finite difference scheme.
