Roller-compacted concrete (RCC) has become one of the most widely used materials for upgrading or replacing aging embankment dams in the U.S. Examples of modifications show that low cost and rapid application are the main advantages of RCC. Dam owners and engineering consulting firms who are users of RCC point to its low cost, provenOver the past two decades, roller-compacted concrete (RCC) dams have been built in many countries due to their technical and economic advantages over conventional vibrated concrete dams and embankment dams. This study sought to create new structural and technological solutions for RCC dams to reduce cement consumption Innovative Structures of Very Lean Roller-Compacted Concrete

The flexural strength of roller compacted concrete can be achieved between 500psi to 1000psi. Flexural strength has a direct relation with the density and compressive strength in this concrete. Bond Strength. Roller compacted concrete is poured into layers. A layer of approximate thickness of 20cm to 10cm is placed and then it is The optimized mixture was developed using dry sodium hydroxide (NaOH) to produce roller-compacted concrete, and the mixture characteristics were analyzed in different weather conditions such as humidity and temperature. The compressive strength after 28 days was 58 MPa at ambient curing and 61 MPa at thermal curing conditions.Structural Behavior of Fly Ash–Based Geopolymer for Roller-Compacted

In the recent past, emphasis was given roller-compacted concrete in the field of pavement construction owing to its proven advantages like fast construction method, high density, and economical when compared with conventional concrete. Roller compacted cement concrete is the name given to stiff concrete that can be compacted by a roller The construction process of Roller Compacted Concrete Pavement (RCCP) is as follows; RCC is mixed in a continuous mixing pug mill or normal mixer used for soil-cement treated base or asphalt concrete construction. The pavement is constructed in lifts of 150-200 mm for a thickness greater than 400 mm.Roller Compacted Concrete (RCC) Civil Giant
