Alkali-Carbonate Rock Reaction at Center Hill Dam, Tennessee
Center Hill Dam, located on the Caney Fork River about 25 miles above its confluence with the Cumberland River in Dekalb County, Tennessee, is the first US Army Corps of Engineers project where alkali-carbonate rock reaction has been identified as a probable cause of cracking in the structure. Expansion of the concrete has opened joints causing excessive leakage between some monoliths, raised the bridge over the spillway, and restricted gate movements. Aggregate in the concrete was produced from a quarry in limestone on the site. Examination of concrete from the structure and of rock samples from the quarry indicated that some of the aggregate used is classified as potentially reactive by the criteria given in Appendix C of the Standard Practice for Concrete (EM 1110-2-2000).
