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.

RCC has the same basic ingredient as conventional concrete: cement, water, and aggregates, such as gravel or crushed stone.

But unlike conventional concrete, it\'s a drier mix—stiff enough to be compacted by vibratory rollers. Typically, RCC is constructed without joints. It needs neither forms nor finishing, nor does it contain dowels or steel reinforcing.

These characteristics make RCC simple, fast, and economical.
