Roller Compacted Concrete(RCC) is made of the similar ingredients as common concrete including Portland cement, aggregates(sand and gravels or crushed stones) and water but is composed of different proportions. RCC first was used to build dams. Over the years, roller-compacted concrete (RCC) has been used successfully for the construction of industrial pavements such as log sort yards, military hard stands, or container yards. In the area of industrial applications, RCC has proven to be extremely competitive compared to high-performance asphalt pavements. RCC now increasingly is used for the construction of pavements exposed to very severe loading and environmental conditions. This growing interest in RCC has prompted contractors and engineers to come up with technical innovations. Placement and consolidation operations have been improved significantly over the years, and new mixture design methods that allow the production of RCC mixtures with optimum packing densities (and minimal binder contents) have been developed recently.
Roller Compacted Concrete Mixture Design
There is actually no commonly accepted procedure to proportion RCC mixtures for pavement applications. Over the years, several methods using different approaches have been used successfully throughout the world. Some were adapted from techniques specifically developed to design RCC mixtures for dam construction while others are more general and can be used to proportion RCC mixtures for paving applications. Most conventional RCC mixture-proportioning methods are essentially empirical procedures that require making a certain number of trial batches to obtain the optimum mixture proportions.
Production of Roller Compacted Concrete Plant
RCC production requires a vigorous mixing action to disperse the relatively small amount of water evenly mixed throughout the matrix. We provide two RCC Plant Type: the continues mixing plant and the central mix concrete batch plant.
Continues Mixing Plant
In Most case, RCC typically is mixed in continuous-flow mixers such as those used for asphalt concrete construction.The main advantage of continuous mixers is the fast production rate, since they can produce 200 to 600 tons of RCC per hour.
Central Mix Concrete Batch Plant
For smaller jobs, where high production rates are less important, RCC can be produced in central mix concrete batch plants. The main advantage of central mix concrete batch plants is that the mixing sequence usually can be modified to allow the premixing of the mortarfraction of the mixture with the chemical admixtures.
