BS EN 14038-1:2016

This standard BS EN 14038-1:2016 Electrochemical realkalization and chloride extraction treatments for reinforced concrete is classified in these ICS categories:

• 91.080.40 Concrete structures

This European Standard specifies a procedure for carrying out impressed current electrochemical realkalization (ER) of carbonated reinforced concrete in existing structures. It is applicable to atmospherically exposed parts of structures with ordinary reinforcement embedded in concrete.

This European Standard does not apply to concrete containing prestressing steel which can suffer hydrogen embrittlement during realkalization, or to concrete containing epoxy-coated or galvanized reinforcement, or if chloride contamination is contributing to reinforcement corrosion.
