W artykule przedstawiono przykłady uszkodzeń betonu w wyniku procesu reakcji alkaliów z krzemionką (ASR) lub alkaliów z węglanami (ACR), które mogą doprowadzić do uszkodzenia i zniszczenia jego struktury. Wizualne symptomy ekspansywnych procesów ASR i ACR oraz przykłady ich występowania zilustrowano zdjęciami.

EN

In the article the examples of concrete damage have been presented as a result of alkali-silica (ASR) or alkali-carbonate (ACR) reactions, which may lead to the damage and destruction of concrete structure. Visual symptoms of expansive ASR and ACR processes and examples of their occurrence have been illustrated with photos.
