Roller compacted dam
WebTransverse joints are perpendicular to the dam axis. A concrete dam is a major construction project that needs a massive amount of concrete, resulting in the use of a large amount of cement. Cement production is causing CO 2 emissions that are detrimental to the environment and is also a high-cost procedure. Roller Compacted Concrete (RCC) Dams WebRoller-compacted concrete (RCC) is a type of concrete that can support a roller during its unhardened state while it is being compacted. The placement and compaction of RCC is a rapid construction process and therefore its success relies on the pre-construction planning and coordination of all interrelated activities.
