Abstract:

Considerations concerning the RCC construction process and its relation with the design and quality are analyzed. The paper contains topics related to the experience obtained at Urugua-i to get a better knowledge of the RCC technology and to allow the use of this construction method in current feasibility studies in Argentina. The procedures are studied. The quality and economic savings obtained through the usage of RCC are considered. An RCC production rate increase at Urugua-i along with quality improvement because of changes in construction layout are analyzed. The importance of the upstream and downstream faces in an RCC dam as the main factor that could improve or hinder RCC placement rate and quality is considered. the use of a combined solution with precast panels lined with a PVC membrane and a conventional concrete face at Urugua-i, is studied in light of the experience obtained during the construction of the dam. The Urugua-i work is described along with problems and solutions found during the works; planning changes performed at this job aiming to improve production rate and quality are studied.
