Abstract
Ingress of chlorides into reinforced concrete elements results in corrosion of reinforcing steel and loss of service life; new evidence also suggests that chlorides can also result in the deterioration of concrete itself. Estimating the rate of chloride ingress in concrete is difficult because current methods depend on measuring concentration profiles using chemical methods. In this paper, we proposed that EIT (Electrical Impedance Tomography) can be used to monitor the diffusion of chlorides into concrete since the presence of chlorides increases the electrical conductivity of the concrete.
