Cathodic Protection of Steel in Reinforced Concrete

Application ID: 11106

This example models cathodic protection of a steel reinforcing bar in concrete.

Three different electrochemical reactions are considered on the steel surface. Charge and oxygen transport are modeled in the concrete domain, where the electrolyte conductivity and oxygen diffusivity depend on the moisture content.

The impact of different moisture levels on the corrosion currents is investigated.

This model example illustrates applications of this type that would nominally be built using the following products:
