RCC arch dam technique tested in Brazil
The advent of roller-compacted concrete (RCC) in the construction of gravity dams has made them more time and cost-effective and a viable alternative to arch dams, and therefore the arch dam market tends to suffer from the competition of the RCC gravity dam. Since the beginning of 2002, Swiss consultant Stucky and Brazilian company Construtora Norberto Odebrecht with the support of international RCC expert Francisco Rodrigues Andriolo have collaborated on the development and testing of an innovative technique to apply RCC to double curvature arch dam construction, thus to make the arch dam more competitive.
