Roller-compacted concrete (RCC) is rapidly becoming a popular material for dam construction, heavy-duty paving, and mass fill applications. Its economy comes primarily from being able to transport and place it in large quantities with minimal time and labor by using earthmoving or conveyor equipment. The no-slump mix is spread with bulldozers and compacted into a solid mass with large vibratory rollers. The effect of compaction methods, water content, and other variables on density, pore pressure, practical construction problems, and permeability are discussed.
