Electrochemical Re-Alkalization and Chloride Extraction Treatments for Reinforced Concrete - Chloride Extraction
Also Known As:
The standard DD CEN/TS 14038-2:2011 provides guidelines for the removal of chloride from existing reinforced concrete structures using impressed current electrochemical chloride extraction. This procedure is specifically applicable to parts of structures that are exposed to atmospheric conditions and contain ordinary reinforcement or post-tensioned tendon ducts embedded in concrete.
It is important to note that for structures with post-tensioned tendon ducts, it is necessary to ensure that there is no risk of hydrogen embrittlement. This may involve conducting trials and installing monitoring systems during the chloride extraction treatment. However, this standard does not apply to pretensioned concrete, as it may be susceptible to hydrogen embrittlement on the stressing bars during chloride extraction. Additionally, concrete containing epoxy-coated or galvanized reinforcement is also not covered by this standard.
