Alkali-Aggregate Reaction

Although potentially reactive aggregates exist throughout North America, alkali-silica reaction distress in concrete is not that common because of the measures taken to control it. It is also important to note that not all ASR gel reactions produce destructive swelling. Alkali-carbonate reaction (ACR) is observed with certain dolomitic rocks.
