✦ Synopsis

Equations to calculate the duration of electrochemical chloride 8! extraction have been proposed and solved for the case of a constant z chloride concentration in the concrete or for a concentration following the error function trend. In the case of constant initial chloride content, both potentiostatic and galvanostatic operation have being considered, while only the potentiostatic one was considered in the case of nonconstant initial chloride profile. Potentiostatic operation has seemed to lead to an easier mathematical calculation. Numerical examples are given to illustrate the mathematical modelling and are also applied to experimental results previously published by Tritthart and Elsener.
