RCC at 10

Article Abstract:

Acceptance and interest in roller-compacted concrete (RCC) as a dam construction method has increased because of its low cost and rapid construction benefits. This emerging construction method has a very wide range of flexible solutions to various dam-related problems. At present, there are no mega-dam projects under contemplation. Emphasis has now shifted to rehabilitating existing dams and this is where RCC is expected to be fully harnessed.

RCC: rehab results

Article Abstract:

Roller compacted concrete (RCC) is a cost-effective material used to control hydraulic deficiency by providing overtopping protection to dams. Dams should have enough mass to resist the negative pressure of the downstream crest, and the upstream slope near the crest should be protected from erosion. There should be no underseepage at the crest. An underdrain system with proper grading and capacity controls uplift.

The many faces of RCC

Article Abstract:

Innovative ideas in the formulation of roller-compacted concrete (RCC) and in the design and construction of dams by China to augment its hydropower supply are discussed. The RCC is high in cementitious content and grout-enriched RCC is used for upstream faces of the dam in a sloping-layer placement method construction.
