Feb 20, 2020 · Roller Compacted Concrete (RCC) is a type of dry consistency concrete usually preferred in dams, airport runways and highway pavement construction applications due to its favourable factors such as durability, cost effectiveness, low hydration heat, rapid and easy implementation [1].

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.

The permeability of Roller Compacted Concrete pavement is largely dependent on the voids in the compacted Roller Compacted Concrete and the porosity of the mortar matrix. Therefore, it is most affected by mixture proportioning, method of placement and degree of compaction.

Jun 9, 2022 · The ever-increasing use of fibres in roller-compacted concrete pavement (RCCP) necessitates fully identifying the mechanical and permeability properties of RCCPs. Incorporating fibres in RCCP with different properties leads to a better comparative investigation that helps discover the unique effects of each fibre on the RCC characteristics.

May 1, 2021 · The permeability of roller-compacted concrete (RCC) substantially affects its functionality and safety. This study investigates the effect of mix design parameters on the performance of RCC. For this purpose, approximately 500 …

Roller-compacted concrete (RCC) is a concrete of no-slump consistency in its unhardened state that is typically transported, placed, and compacted using earth and rockfill construction equipment.

Nov 16, 2023 · Roller compacted concrete was found to be considerably more permeable than conventionally proportioned and placed concrete and somewhat more permeable than conventional mass concrete. The use of silica fume and finer cement appeared to reduce the coefficient of permeability to some extent.

Roller-compacted concrete (RCC) is a relatively stiff or zero slump concrete mixture that is compacted by vibratory rollers. Although the term roller-compacted concrete is of recent origin (early 1970s), similar materials-mixtures of cement, aggregate, and water-have been used for a much longer time.

Jul 7, 2015 · Roller compacted concrete is a very dry material consolidated by the use of a powerful external vibratory compaction. It can be defined as concrete of no-slump consistency in its unhardened state that is transported, placed and compacted using earth and rockfill construction equipment.

Aug 1, 1997 · Special emphasis is placed on recent innovations based on the optimum paste volume and optimum packing density concepts. Each method is evaluated on the basis of its ability to yield cost-effective RCC mixtures with optimum …

Mar 1, 1994 · High-strength RCC tends to behave more like conventional concrete with sudden and rapid failure after reaching its elastic limit. Understanding the potential material properties of RCC and utilizing appropriate values in design is crucial …

It was found that roller compacted concrete is much more permeable than conventionally proportioned and placed concrete, and somewhat more permeable than conventional mass concrete. The use of silica fume and finer cement appears to reduce the coefficient of permeability to some extent.

May 1, 2021 · Roller compacted concrete was found to be considerably more permeable than conventionally proportioned and placed concrete and somewhat more permeable than conventional mass concrete.

Roller-Compacted Concrete (RCC) consists of an engineered mixture of dense-graded aggregates, cement and water. This zeroslump concrete mixture, when placed with an asphalt paver and compacted to high density, provides a high-strength, durable pavement structure.

Roller-Compacted Concrete (R CC) consists of an engineered mixture of dense-graded aggregates, cement and water. This zeroslump concrete mixture, when placed with an asphalt paver and compacted

In roller-compacted fast-curing concrete, permeability is reduced, chloride ion permeability is decreased, abrasion resistance and impact resistance are increased by the use of macro-synthetic fibers (Lee, Jeon, Cha, & Park, 2017).
