Alkali-aggregate reaction



Alkali-aggregate reaction is a reaction which occurs over time in concrete between the highly alkaline cement paste and non-crystalline silicon dioxide, which is found in many common aggregates. This reaction can cause expansion of the aggregate, leading to spalling and loss of strength of the concrete.
