<p>Ground motion effect on a roller-compacted concrete (RCC) dams in the earthquake zone should be taken into account for the most critical conditions. This study presents three-dimensional earthquake response of a RCC dam considering geometrical non-linearity. ...

This report compares two different dam types (Roller Compacted Concrete Dam and Concrete Face Rock-fill Dam) in order to help the decision making when choosing what dam type to build in Panama, where Vattenfall is involved in a joint venture to build a dam ...

RCC is batched and mixed onsite using a portable mixing plant. Occasionally, one or more aggregates are obtained on or near the site and graded to conform to the specified aggregate gradation. It is more common to purchase aggregates from an aggregate supplier ...

<p>The development of the roller-compacted concrete (RCC) technology in the 1980s is considered by many as a significant breakthrough in the construction industry. RCC is now commonly used all around the world for the construction of dams and pavements, and ...

In the last 25 years, following the completion of the Willow Creek ‘all’ RCC dam, the experience and knowledge gained through the completion of over 350 RCC dams has been considerable. Many new ideas and innovations have been tested and adopted so that today ...

<p>Roller-compacted concrete (RCC) is used throughout the world for new dam construction. In the United States, RCC is also used extensively for modifying dams with safety deficiencies including stability buttresses for concrete dams, overtopping protection ...

<p>The world&rsquo;s first roller-compacted concrete in dams was started in October 1978 in Japan. Since then, for just 30 years, about 50 roller compacted concrete dams have been constructed in Japan. This rollercompacted concrete is called RCD (Roller Compacted ...

It is the purpose of this paper to show how RCC design and construction techniques were developed with time and how RCC is today applied in a general way at South African dams.

The technologies for construction of roller-compacted concrete (RCC) dams have been considerably developed during recent years in China. At the time being, they have been successfully applied to the constructions of even extreme-high gravity dams and medium ...

Roller compacted concrete (RCC) dams and concrete-faced rockfill (CFR) dams have become viable alternatives to large conventional concrete and embankment dams because of their considerable potential economic benefits. These new dams create also new risks, ...
