BS EN 14038-1:2016 PDF Download

BS EN 14038-1:2016 is a European Standard that outlines the procedure for carrying out impressed current electrochemical realkalization (ER) of carbonated reinforced concrete in existing structures. This standard specifically applies to the atmospherically exposed parts of structures with ordinary reinforcement embedded in concrete.

It is important to note that this standard does not apply to concrete containing prestressing steel, as hydrogen embrittlement can occur during the realkalization process. Additionally, the standard does not cover concrete containing epoxy-coated or galvanized reinforcement, or cases where chloride contamination is contributing to reinforcement corrosion.

The standard includes a note mentioning that in the case of post-tensioned prestressing concrete, the exposed tendon strands may be shielded by the tendon ducts to prevent unwanted or excessive polarization into the cathodic range and subsequent water reduction.
