## Abstract In this paper a mathematical description and numerical implementation for ion transport in concrete due to current passage is developed, in which the heterogeneous equilibrium between Ca^2+^, OH^β^ and the solid Ca(OH)~2~ is incorporated. The description is based on the NernstβPlanck eq

## Abstract A mathematical model is being developed to describe a repair method in concrete, called cathodic protection (CP). The model is in principle also useful to describe electrodeposition in concrete, e.g. the process of reβprecipitation of Ca(OH)~2~ invoked by an electrical current. In CP, t
Cathodic protection modelling often involves making assumptions about geometric features and material characteristics that directly impact accuracy of solutions. In the present paper, predictive power of the model using approximate uniform current boundary condition on the cathode is validated again
Corrosion of steel embedded in concrete was modelled using a 4m long beam containing a bar in seven segments, one mild steel and six stainless steel, which could be electrically connected or isolated by external switches. The concrete mix was dosed with 3% Cl to initiate corrosion. The current flowi
