Monitoring of Corrosion Behaviors of the Rebar Immersed in Simulated Pore Solutions of Concrete by the Coulostatic Method

Using a coulostatic perturbation meter and a computer as on line measurement system, the corrosion behaviors of the rebar immersed in simulated pore solutions of concrete with different pH values, were monitored. A comparison was carried out between the potential method and the coulostatic method, the results indicated that the coulostatic method is more sensitive and quantitative than the potential one.
