Název v původním jazyce

Rehabilitation of Reinforced Concrete by Electrochemical chloride extraction and Nanoparticle Injection

Popis výsledku v původním jazyce

The lecture is intended to cover experimental investigations and numerical solution of the diffusion-convection problem applied to chloride migration. The solution is implemented into an in-house open-source FEM software and several practical tests are simulated and shown, namely the chloride penetration and extraction on lab samples and on an R/C element. In both cases, chlorides can migrate due to diffusion or convection which is, in our case, caused by an externally applied electrical field. The electrical field accelerates the chloride migration by multiple times compared to natural diffusion and can be used for repairing the concrete in a reasonable time frame (several days).
