Electrochemical lithium migration to mitigate alkali-silica reaction in existing concrete structuresSilva de Souza, L.M. (author)Alkali-silica reaction (ASR) is a deterioration process that affects the durability of concrete structures worldwide. During the reaction, hydroxyl and alkali ions present in the pore solution react with reactive silica from the aggregate, forming a hygroscopic ASR gel. Alternatively, the silica structure is attacked by hydroxyl ions and the...doctoral thesis 2016
