Roller Compacted Concrete (RCC), is a concrete with zero slump, which is used in damming and road pavement. Roller Compacted Concrete Pavement (RCCP) bear heavy traffic loads and severe weather conditions. This type of concrete is due to its economic and environmental capabilities, including reduced construction and maintenance costs, longer durability and longer lifetime, as well as environmen...

Roller compacted concrete (RCC) is a material with no slumps and made from the same raw materials as conventional concrete. The roller dam method, high paste technique, corps of engineers maximum density method are all ways designing RCC. evolution RCC has resulted in substantial change construction projects, most notably dams, because sluggish pace placement, consolidation, compacting. process...

RCC using hematite as an aggregate has interesting characteristics for use in massive structures or radiation shielding. In Brazil, there is a considerable amount of ore tailings without practical use, which makes this material environmental problem and matter public safety. Thus, the search alternatives to these priority concern. An containment dam with was constructed protect basin Barao de C...

This Engineer Technical Letter (ETL) discusses the special problem areas and concerns related to RCC construction in order to assure that the concrete properties required are ultimately realized in the completed structure. A quality RCC product requires a coordinated effort between the structural designer, the materials engineer, the materials laboratory, and those responsible for field quality...

recently, particular attention has been paid to the stepped spillways due to the increasing effect of energy dissipation and the reduction of cavitations risks with the development of roller compacted concrete (rcc) technique. flow regimes on the spillways divide into three groups, namely skimming, jet and transition flow. compared to the numerical methods, the majority of performed studies in ...

Earth-moist concrete mixes are the starting substance for the mass production of concrete products like pipes, slabs, pavement stones and curb stones. The working properties of earth-moist concrete (EMC), caused by its dry consistency, are advantageous. So, in comparison to normal-weight concrete, the consistency of EMC allows for direct stripping of concrete products after filling and vibratin...
