- CVC does not have the ability to support a roller while being compacted. On the other hand, RCC is a concrete in its unhardened state that will support a roller while it is being compacted. At early stage, RCC is only applied in pavement construction.Item Type: Student ProjectProgramme: Bachelor Engineering (Hons) (Civil)

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 fly …
