Electrochemical realkalization and chloride extraction treatments for reinforced concrete - Part 2: Chloride extraction
Also Known As:
The DIN EN 14038-2 standard focuses on the procedure of electrochemical chloride extraction (ECE) for reinforced concrete structures. The standard specifically addresses the process of removing chloride ions from existing structures through the use of impressed current. It is intended for use in atmospherically exposed parts of structures with ordinary reinforcement and post-tensioned tendon ducts embedded in concrete.
One important consideration highlighted in the standard is the potential risk of hydrogen embrittlement, particularly in structures with post-tensioned steel. To mitigate this risk, the standard emphasizes the importance of conducting trials and monitoring during the chloride extraction process to ensure that there is no hydrogen embrittlement. It is important to note that this standard does not apply to concrete containing pre-stressing steel, as it can be susceptible to hydrogen embrittlement during the chloride extraction process. It also does not apply to concrete containing epoxy-coated or galvanized reinforcement.
