Abstract
Finland is known as a country having very durable granitic aggregate that is used in a wide range of construction applications. Yet recent field results from existing concrete structures have shown evidence of alkali aggregate reactions (AAR). In Finland there is a need to have a better understanding of what causes AAR and from what aggregate sources, how to identify it or separate it from other deterioration mechanisms and guidelines about how to avoid AAR in future construction. This paper shares information about a few of the Finnish structures where AAR has been detected.
