EN 14038-2 Electrochemical Chloride Extraction
Post date: 11 March 2021
The purpose of chloride extraction is to rehabilitate a reinforced concrete part from corrosion activity non-destructively and to provide long term corrosion protection of steel reinforcement in concrete which has been affected by chloride. The duration of the treatment is from several weeks up to as much as several months, depending on the amount and ingress depth of accumulated chloride, the permeability of the concrete, the layout of the reinforcement and other factors.
There are other electrochemical procedures that can be used to provide corrosion protection to steel in concrete structures. These include cathodic protection and re-alkalization. There are European standards for cathodic protection of steel in concrete (EN ISO 12696) and for the re-alkalization of carbonated concrete (EN 14038-1).
It has been assumed in the drafting of this document that design and execution of a chloride extraction application will be entrusted to appropriately qualified, competent and experienced people, for whose use it has been prepared.
