Roller-Compacted Concrete - an overview ScienceDirect Topics

Roller-compacted concrete (RCC) is a special dry concrete with zero slump made from the same constituents as ordinary concrete but with low cement content. It is usually compacted like a soil. RCC is mainly used for the construction of massive structures such as dams or large horizontal surfaces like highway foundations. Its low cement content reduces the development of temperature in mass ...

Roller Compacted Concrete

Roller Compacted Concrete pavement is best described as a zero slump concrete that is placed with standard or high-density paving equipment and consolidated/compacted using steel-drum or rubber-tired rollers to achieve a durable, wear resistant surface. Roller-Compacted Concrete pavements were first used in the 1970’s for stabilization of ...

Roller Compacted Concrete Included in DMRB - Britpave

Roller compacted concrete (RCC) takes its name from the construction method used – it is placed by modified asphalt paving equipment, but it is stiff enough to be compacted by vibratory rollers. RCC requires no formwork or reinforcement, the surface texture is smooth and suitable for parking, materials handling and road pavements where the traffic speeds are relatively low ( 60km/hour).

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.

Placement of Roller-compacted concrete. The mix is placed in layers (or lifts) 4-9 inches thick. Compaction of Roller-compacted concrete. Steel drum vibratory rollers compact the concrete. Compaction is the most important step in Roller-compacted concrete (RCC) construction because it provides density, strength, smoothness, and surface texture. The process begins immediately after

Surface treatments can be applied when the development nears completion. When traffic speeds are greater than 30 mph, surface smoothness is important. To achieve better surface smoothness, most projects use high-density pavers and/or diamond grinding. A thin asphalt surface course placed on top of the Roller Compacted Concrete is another option.

Benefits and Costs of Roller-Compacted Concrete

25/11/2019  Roller compacted concrete (RCC) was originally limited to the sub-base of roads and airfield pavements, being called lean concrete or dry lean concrete. This type of concrete has become very popular due to the fact that it is a simple material to produce and because it can be placed fast while producing a great surface.
