摘要

Corrosion of steel reinforcement can seriously compromise the service life of reinforced concretestructures. Hence, service life prediction and enhancement of concrete structures under corrosionattack are of significant importance. As a result, numerical methods that can reliably predict the servicelife of concrete structures have attracted increasing attention. In this, the first of two companionpapers, a simple and significantly improved inverse relation relating the current density with potentialfor the cathodic reaction is proposed. This enables the current densities to be determined accuratelyfrom the measured potentials. Equally importantly, the proposed inverse relation also enables theefficient and straight-forward nonlinear algorithm for modeling of steel corrosion in concretestructures to be developed. Such an algorithm is presented in the companion paper of this.
