Title: Alkalicarbonate Rock Reaction at Center Hill Dam, Tennessee
Author(s): Thomas L. Hugenberg
Publication: Special Publication
Appears on pages(s): 1883-1902
Keywords: alkali-carbonate reactions; bridges (structures); concrete cores; concrete dams; evaluation; expansion; repairs; spillways; tests; Construction
Abstract:Expansion of the concrete at Center Hill Dam during its 38-year service life resulted in binding of the spillway gates and closing of the expansion joints in the bridge spans in 1983. An extensive laboratory and field investigation identified an alkali-carbonate rock reaction as the cause of expansion. Shortening of the spillway gates and bridge spans in 1985 remedied the operational deficiencies.
