Roller Compacted Method

Roller-compacted concrete - Wikipedia

Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for Portland cement. The partial substitution of fly ash for Portland Cement is an important aspect of RCC dam construction because the heat generated by ...

Roller-Compacted Concrete (RCC) - cement.org

Roller-compacted concrete, or RCC, takes its name from the construction method used to build it. It's placed with conventional or high-density asphalt paving equipment,then compacted with rollers. Roller-compacted concrete has the same basic ingredient as conventional concrete: cement, water, and aggregates, such as gravel or crushed stone.

ROLLER-COMPACTED CONCRETE

In roller-compacted concrete dams the drainage gallery often increases construction time and increases costs because the earthfill method being used does not easily accommodate such a construction. One possible method to decrease gallery construction time is to use precast concrete gallery segments, however this method has not yet been attempted.
