RCC roller concrete is concrete that is used in the implementation of bulky structures (dams, large foundations, etc.) and for its implementation, road construction machinery and earthworks are used.
By definition, roller concrete is concrete with zero slump and is used by earthmoving machinery to transport, disperse, and compact it. Easily play.
On the other hand, in order to create adhesion between the aggregates, it must be moist enough that the concrete syrup provides the necessary coverage for all aggregates.
Therefore, rolled concrete in unconcentrated state is very different from ordinary concrete, so that in this case, no trace of concrete juice is visible in the mixture and acts like soil materials, but after compaction and hardening, like ordinary concrete (With the same ratio of water to cement) will behave.

In the Concrete and Cement Glossary of the American Concrete Association, roller concrete is defined as: roller-compacted concrete, concrete that is compacted by not moving in a hard state. It is also referred to in the technical literature as rollcrete.
This method is often used today as roller concrete or in short. RCC to hardened roller concrete has essentially the same properties as ordinary concrete, which is poured and placed in place, and the final product is simply called "concrete".
Investigation of roller concrete specifications and its use in road pavement construction:
One of the types of materials that has been developed in recent decades for use in road pavement construction is roller concrete (RCC).
Rolled concrete pavement (RCCP) can be used for light traffic routes as well as heavy traffic routes and the rolled concrete surface used in this type of pavement has features such as high durability, low construction costs and maintenance on surfaces. is low.
According to the study, it is observed that roller concrete pavement compared to flexible pavement that is commonly used in Iran, has a much lower cost and can be used cementitious materials such as fly ash and microsilica that use They are common in ordinary concrete, also used in the manufacture of roller concrete.
Also, the damages caused in roller concrete pavement are much less compared to flexible pavement, especially for heavy traffic routes.
In addition, some issues related to the implementation of roller concrete pavement such as road surface roughness can be solved by applying a thin layer of asphalt on the roller concrete layer or grinding it.
Roller concrete slide:
The psychological and plastic properties of roller concrete in the wet state are fundamentally different from the plastic properties of conventional in-situ concrete. The slip of the roller concrete must be at zero to be able to withstand the weight of the compactor roller.

Machines used for transportation, loading and compaction of Rcc concrete include high capacity machines that are used in large earthworks, such as dams and road construction.
In general, in roller concrete making, the amount of manual (non-machine) operation required is less compared to conventional concrete construction operations.
Due to the environmental issues caused by asphalt along with the low durability of asphalt against climate change, impact and wear, the issue of RCCP concrete has been considered in developed countries for decades.
At present, more than 80% of carriageways in most developed countries have been constructed using roller concrete.
History of RCC concrete:
Due to the vulnerability of earthen dams, experts at the Asiolmar Conference and other researchers were looking for a new type of material for dam construction that has both the safety of the concrete dam and the speed of construction of the earthen dam.
Until in the early 1960s and 1970s, a new initiative to build a roller concrete dam was introduced. In the 1960s, several projects were designed with the idea of combining the benefits of concrete and earth dams. These mixed dams were the result of studies and innovations by structural and geotechnical engineers.
Unfortunately, due to the specialization of each of these two disciplines, there was a limited relationship between the early pioneers. Accordingly, the specialists of each of these two disciplines had limited knowledge of each other's initial efforts.
Rolling concrete dams (R, C, C) were introduced as a new type of dam during the 1980s. These types of dams are accepted all over the world due to their low cost, part of which is due to their rapid construction in a relatively short time, and cause significant sudden progress in design and construction.
The application of this was introduced in the 1990s and after: This dam is less expensive and safer than classic concrete dams. Rolled concrete is a new way of construction rather than a new type of material. Rolled concrete with cemented soil, which is applied in similar ways.
Execution methods and consequences of roller concrete:
To answer the question "How is roller concrete made?" It should be said that the energy required to run and accommodate such materials is more than the amount provided by conventional vibrators.
For this reason, in case of using cementitious materials similar to those used in traditional vibrating concrete (CVC) or conventional concrete, and by applying successive layers of concrete, a better quality than conventional concrete (CVC) can be achieved. .
On the other hand, like earthen dams, the area between two successive layers and the area within the layers are different.
How is roller concrete applied?
The method of rolled concrete compared to conventional concrete, allows to achieve higher speeds, which will have economic benefits such as saving the unit price of concrete volume and a significant reduction in construction time, as well as in the formwork and..
Roller concrete, like all available types of concrete, is a mixture of neutral stone materials, cementitious materials and water.
Rolling concrete is a new material and method for economical construction of bulky structures, including weight dams. In this type of concrete, a combination of concrete and soil technology features is used and it is transported, spread and compacted by using earth dam construction machines.
Therefore faster concreting and implementation costs are greatly reduced.
Today, roller concrete dams are being built in many developing countries. Because these dams have economic benefits and speed
