Alkali Aggregate Reaction in Concrete Types Causes and

Alkali aggregate reactions AAR occur when aggregates in concrete react with the alkali hydroxides in concrete producing a hygroscopic gel which, in the presence of moisture, absorbs water and causes expansion and cracking over a period of many years. This alkali-aggregate reaction has two forms, namely Alkali-silica reaction ASR and Alkali-carbonate reaction ACR. The former
