The mathematical model for the chloride-induced corrosion of reinforcing steel in concrete is applied to analysis of the influence of the concrete quality (w/c ratio), concrete cover thickness and the degree of water saturation on the corrosion current density. The governing equations of electrical potential and oxygen transport through concrete, as well as the boundary conditions for the polarisation on the cathodic part of steel surface are described. The numerical procedure based on the finite element and finite difference method is developed to solve the set of equations. |
