Roller Compacted Concrete Pavement - RCC Pavement Council

Roller Compacted Concrete (RCC) in general has two major markets: pavements and water resources (dams, spillways, reservoir slope protection, etc.) While there are water resource applications which are placed similar to RCC pavements, the materials, engineering properties, and construction means and methods for pavements are typically different

Roller Compacted Concrete Dams | High performance mixing

Roller Compacted Concrete Dams If you are considering producing large volumes of concrete for dam construction, Aran mixing and process systems are ideal – since the early 1980's Aran has been involved with and promoted Roller Compacted Concrete (RCC) dam construction on a global scale.

Guide for Roller-Compacted Concrete Pavements

Guide for Roller-Compacted Concrete Pavements Abstract Roller-compacted concrete (RCC) is an economical, fast-construction candidate for many pavement applications. It has traditionally been used for pavements carrying heavy loads in low-speed areas because of its relatively course surface.

Concrete / Rollercrete Dams | Geoengineer.org

Roller Compacted Concrete (RCC) Dams. Roller Compacted Concrete (RCC) dams are made of a composite construction material with no-slump consistency in its unhardened state. RCC is made from a mix of cement/fly ash, water, sand, coarse aggregate, and common additives, but contains much less water compared to conventional concrete.

Our mixers are designed to handle demanding mixing tasks. When it comes to earth-moist concrete formulations, place your trust in the globally proven mixing technology of BHS. Hydraulically-bound base layers, often also referred to as roller-compacted concrete (RCC), have been used for many years in the construction of roads, runways and dams.

Centennial Reservoir Project Roller Compacted Concrete Dam

Oct 04, 2015 · construction schedules and costs of two potential dam types [roller compacted concrete (RCC) and concrete faced rockfill (CFR)] and two potential dam axis alignments (Axis 2 and Axis 6) (AECOM, 2016). The schedules indicated that the RCC dam could potentially be constructed in about 2½ years, but the CFR dam would take about 4 years to construct.

Roller Compacted Concrete - Structural Guide

Roller Compacted Concrete is a kind of concrete that contains fine aggregates, coarse aggregates, cement, and water. In addition, additives like fly ash may be added as per the requirement of the project. Therefore, the material types used in RCC are the same as other types of concrete. Generally, the aggregate size is higher than the normal

Roller Compacted Concrete: Types, Advantages & Disadvantages

Roller-compacted concrete (RCC) or rolled concrete (Rollcrete) is a special blend of concrete that contains essentially the same ingredients as conventional concrete, but in different proportions and increasingly with partial replacement of fly ash for Portland cement.. It is placed in thin layers to allow full compaction with layer thicknesses ranging from 20 to 30 cm.

Roller Compacted Concrete | Gears, Inc.

RCC, When properly mixed and placed, takes on the properties of conventional concrete. Placement is accomplished utilizing conventional construction equipment. In dam construction or dam rehabilitation, the RCC mix is generally spread with a dozer in level lifts and compacted with a steel drum vibratory roller.
