Realkalization, also known as electrochemical realkalization treatment (ERT), applies an electric field between the reinforcement in the concrete and an externally mounted anode mesh. An alkaline electrolyte is transported into the concrete, increasing the alkalinity of the cover zone, returning the steel reinforcement to a passive condition in the process.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31298642"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14053496"> <skos:prefLabel xml:lang="es">realkalization (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9823626"> <skos:prefLabel xml:lang="ca">realkalization (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:21:50</dct:created>  </skos:Concept></rdf:RDF>
