Diagnosis and Control of Alkali-Aggregate Reactions in Concrete

Aggregates containing certain constituents can react with alkali hydroxides in concrete. The reactivity is potentially harmful only when it produces significant expansion.(1)** This alkali-aggregate reactivity (AAR) has two forms—alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR, sometimes called alkali-carbonate rock reaction, or ACRR). ASR is of more concern than ACR because ...

Importance Of Alkali-Aggregate Reaction. Important factors promoting the alkali-aggregate reaction of aggregates are as follows: When you use a reactive type of aggregates instead of a non-reactive type then it triggers an alkali-aggregate reaction. If you have high alkali content in cement then that also triggers an alkali-aggregate reaction.
