Abstract

Stirrup in the concrete structure has noteworthy effect on the electrochemical chloride removal (ECR), which was always ignored in the numerical simulation. Taking the impact of stirrup into consideration has disadvantages on improving the accurate of modeling results. In this paper, a three dimensional (3D) numerical model considering the impact of stirrup on ECR treatment was established, and an experiment was numerically studied to explore the validity of the model. The difference between the residual chloride concentration of simulation and experiment in most region of the concrete structure is within ± 25%. Based on this model, the effect of stirrups on ECR’s efficiency were explored. The results of numerical model shows that the stirrup has shielding effect on the chloride migration of the region between the stirrups, while in the region near the stirrup, it has positive on the chloride removal.

Numerical simulation on the influence of stirrups during electrochemical repair
