Modeling Electromigration of Chlorides and Nanoparticles in Concrete
Original language description
The paper presents an effective numerical framework for the solution of practical problems related to steel corrosion in reinforced concrete structures. It uses the Fick’s law, Nernst-Planck equation and Gauss law of electrostatics to solve lab expreriments as well as real cases. Finite element model and the Galerkin-Petrov approach is used to solve several tasks. Lab experiments are simulated in one dimension to assess diffusion coefficient of a plain concrete and of a concrete treated by electromigration of nanoparticles. The solution is given for the problem of diffusion of chlorides to the reinforced concrete beam and for the electrically accelerated extraction of chlorides from the structure. The potential use of nanoparticle treatment is demonstrated by an order of magnitude decrese in diffusion coefficient. Electro-extraction treatment was found very effective in the concrete cover while less effective behind the reinforcement.
