roller compacted concrete (rcc) is a type of concrete compacted by roller compaction: it is the concrete that, in its unhardened state, will support a roller while being compacted. by definition rcc is simply a concrete that has a consistency which allows it to be spread with a bulldozer and compacted with a vibratory roller.
this document is intended to cover the primary design requirements for hollow core floor and 2.2.1 aci requirements 2--1..... 2.2.2 stresses at transfer 2--2 with the concrete being compacted around the cores. the second system uses a higher slump concrete.
bureau of reclamation (reclamation) has used roller-compacted concrete (rcc) for a wide variety of applications, including stability buttresses for masonry gravity and concrete arch dams, overtopping protection and upstream slope protection for embankment dams, new
