ABSTRACT
Evaluation of Roller Compacted Concrete (RCC) dam performance is limited to the relatively short time since they started to be constructed about fifteen years ago. However, since then more than 250 RCC dams have been constructed. The number of RCC dams and the vast range of details, sizes, and locations allow both generalized and detailed comments to be made with regard to performance. Performance involves design and construction issues in addition to strength and operation of the completed structure. Completed RCC dams are performing their intended purpose. Each type of RCC material and design tends to have advantages and disadvantages, or to perform better in some areas than in other areas. This includes seepage, in-situ strength and properties including lift joints, cracking, and durability.
