non-uniform corrosion
The impact of non-uniformity and resistivity on the homogenised corrosion parameters of rebars in concrete – a circuit model analysis
This research develops a circuit model to simulate non-uniform rebar corrosion in concrete, revealing that concrete’s resistivity causes non-uniform rebar potential, affecting polarisation curves. This leads to overestimated Tafel constants and corrosion current density, particularly under higher concrete resistivity. Accurate corrosion predictions require potentiodynamic scans or averaging techniques like this model.
