Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for portland cement. [2]

碾压混凝土重力坝是二十世纪八十年代以来发展较快的一种新的筑坝技术，其是把土石坝施工中的碾压技术应用于混凝土坝，采用自卸汽车或皮带输送机将干硬性混凝土运到仓面，以推土机平仓，分层填筑，振动压实成坝。 碾压混凝土重力坝一般用英文简写为RCC dam。 RCC为roller compacted concrete（碾压混凝土）的简写。 [1] 在二十一世纪初的十几年来，全世界已建和在建的上百座碾压混凝土坝中，大多数为重力坝。 1980年在日本建成岛地川坝（坝高89米）为世 …

The term “Roller-Compacted Concrete (RCC)” describes the concrete used in the construc- tion of dams, combining the cost-effective and rapid placing techniques that are used for earth-fill dams, with the strength and durability of concrete, and gets its name from the

2022年7月6日 · The concept of roller compacted cement (RCC) which is a lean concrete (less cementitious material) and can be placed and compacted by using earth moving equipments which are generally used in embankment dam construction, was used for construction of concrete gravity dam for the first time on Shimajigawa Dam in Japan in 1978.

RCC construction techniques have made RCC gravity dams an economically competitive alternative to conventional concrete and embankment dams. This reveals that initial acceptance of RCC construction was stronger for the dams of the

Roller-compacted concrete (RCC), which takes its name from the construction method used to build it, is a concrete of zero-slump consistency in its unhardened state. It is defined as concrete compacted by roller, as per ACI 207.5R.

2020年6月1日 · The roller-compacted concrete (RCC) dam is a relatively new type of dam, which has evolved rapidly in recent years. Compared with traditional concrete dams, the RCC dam has comparable structural strength, and its roller-compaction construction method, similar to earth-rock dam construction, makes field operation more efficient.

2011年9月27日 · Ted Warren discusses the history of roller compacted concrete (RCC) dam construction and its various applications and advantages to gravity dam design and construction

2018年2月1日 · Key features of roller-compacted concrete (RCC) dams are highlighted, using various dam types as examples. Topics include lift interfaces, facing systems, spillways, intakes and outlets, internal galleries, and joints.

Roller-compacted concrete, which emerged as a viable means of constructing dams in the 1980s, allows much faster and less expensive construction than traditional methods. Roller-compacted concrete has several advantages and disadvantages …
