Chickamauga Dam is a multi-purpose project constructed by the Tennessee Valley Authority (TVA) in the early 1940s. Shortly after construction it was evident there was an alkali-aggregate reaction taking place in the concrete structures. This reaction resulted in a phenomenon of concrete growth; i.e., unchecked expansion of the concrete which causes high stresses, cracking and movement of concrete structures, and undesirable side effects. This problem has increased in severity resulting in increased concerns about structural integrity of the dam structures and long term outages to navigation.
