RCC is placed with conventional or high-density asphalt paving equipment, then compacted with rollers. It has the same basic ingredient as conventional concrete: cement, water, and gravel or crushed stone. But unlike conventional concrete, its drier mix is stiff enough to be compacted by vibratory rollers and can be constructed without joints. It needs neither forms nor finishing, nor does it contain dowels or steel reinforcement. These characteristics make RCC simple, fast, and economical.
