Abstract
The aim of the study is to simulate the effect of anode-cathode displacement and anode type on the potential distribution of reinforced concrete (RC) cathodic protection (CP) system using boundary element method (BEM). For the simulation, Laplace equation was used to model the RC domain. The boundary conditions for the anode and cathode (reinforcing steel/rebar) were represented by its polarization curve. By using BEM, the electrical potential values on the whole domain should be calculated. Therefore, the effects of those parameters were studied based on the rebar electrical potential. For the study, the CP system model and geometry were obtained from a previous researcher. The BEM simulation results show that the anode-cathode displacement affects the distribution of electrical potential on the protected reinforcing steel. It was consistent with the previous research result. The results also show, as expected, that the anode type influences the electrical potential value on the rebar. Hence, those parameters should be considered in designing and/or evaluating the RC CP system.
Highlights
Corrosion is the phenomenon of metal deterioration because of its interaction with the environment
The results show that the distribution of electrical potentials in the protected structures could be performed by boundary element method (BEM)
By using the boundary conditions (BC) as described in the previous section, BEM was executed in order to obtain electrical potential on the surface of rebar
Summary
Corrosion is the phenomenon of metal deterioration because of its interaction with the environment. The infrastructure sector is one of the sectors that impacted by corrosion The effect of parameters on the CP system of the RC structure still necessary to be further understood because of might influenced the performance of the system [9]. The results show that the distribution of electrical potentials in the protected structures could be performed by BEM. This capability will be beneficial in both the design process and the evaluation of the CP system. This research aims to simulate a cathodic protection system on an RC structure using BEM in order to study the effect of anode-cathode displacement and anode type on the distribution of electrical potentials on the reinforcing steel
