A Quantitative Study of Concrete-Embedded Steel Corrosion Using Potentiostatic Pulses

The corrosion rate of steel in reinforced concrete structures may be estimated from the potential decay curve after a pulse interruption, provided that the steel surface area intervening in the measurements is known. Considering that the time constant (τ) of the corrosion process is independent of the surface area, it is also possible to determine the corrosion rate from direct measurements of τ without the need to know the rebar surface area,...
