ROLLER COMPACTED CONCRETE FOR DAM

2011-7-1  Roller Compacted Concrete (RCC) has been rapidly developing over the past 40 years and is now commonly used for mass concreting operations typically in a Gravity Dam application. With a widely varied methodology of design theories and project specific considerations, RCC is not only extremely practical from a constructability standpoint; it is also, along with other advantages, very cost effective.

Roller-Compacted Concrete - an overview ScienceDirect

Roller-compacted concrete (RCC) is a low-cost, fast method for concrete construction and repair. When working with dams, RCC can be used to repair damaged overflow structures, to protect embankment dams during overtopping, and to raise the crest of a dam. Another use is to build a buttress on the downstream side of dams to increase dam strength.
