Roller-Compacted Concrete - an overview ScienceDirect

Roller-compacted concrete (RCC) is a special dry concrete with zero slump made from the same constituents as ordinary concrete but with low cement content. It is usually compacted like a soil. RCC is mainly used for the construction of massive structures such as dams or large horizontal surfaces like highway foundations.
