The rebuilt upper reservoir of the Taum Sauk plant, nearing completion in this photo, is the largest RCC dam in North America. [1]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.

The category lists dams constructed primarily with roller-compacted concrete (RCC). They include arch and gravity dams currently proposed, under construction or completed. Contents
The construction of the dam started on October 25, 2007 and its first generator was operational on November 19, 2011. The roller-compacted concrete arch-gravity dam has a maximum height of 99.2 metres (325 ft) and length of 600 metres (2,000 ft). The upstream vertical face arch radius is 525 metres (1,722 ft).
Hoover Dam from the air. Arch-gravity dams are dams that resist the thrust of water by their weight using the force of gravity and the arch action. [3]An arch-gravity dam incorporates the arch's curved design which is effective in supporting the water in narrow, rocky locations where the gorge's sides are of hard rock and the water is forced into a narrow channel.
The San Roque Dam, operated under San Roque Multipurpose Project (SRMP) is a 200-meter-tall, 1.2-kilometre (0.75 mi) long embankment dam on the Agno River. It is the largest dam in the Philippines and sixteenth largest in the world (see List of largest dams in the world ).
Ciriaco Nadres in 1872 constructed a dam made of adobe to irrigate his farms. His property was later sold to Placido Escudero in 1890. The dam was later enhanced in 1904 using concrete and expanded in 1937 to generate 90 KVA electricity for communities in Quezon, making it the first mini-hydroelectric dam in the Philippines.
Roller gates of Mississippi River Lock and Dam No. 15, the largest roller dam in the world. Roller dams are a type of weir, or a dam that is designed to allow water to flow over the top in continuous action. They are used on rivers or other such moving bodies of water where erosion damage is undesirable, yet likely to occur. A short wall, lip ...
The dam's feasibility study and detailed engineering designs were performed by SMEC. [10] The Kohala hydroelectric scheme will have a gravity, roller-concrete compacted dam on the upper branch of the Jhelum, 40 km from Muzaffarabad. The powerhouse, on the lower branch of the Jhelum near Barasala, will house four 281-MW Pelton turbines.
