Alkaliaggregate Reaction

Alkali-Aggregate Reaction. In most concrete, aggregates are more or less chemically inert. However, some aggregates react with the alkali hydroxides in concrete, causing expansion and cracking over a period of many years. This alkali-aggregate reaction has two forms alkali-silica reaction ASR and alkali-carbonate reaction ACR.
