Roller-compacted concrete (RCC) is a specific blend of concrete used in large civil projects such as dam construction. RCC takes its name from the construction method used to build it. It is placed with conventional or high-density asphalt paving equipment, then compacted with rollers. RCC has the same basic ingredients as conventional concrete: cement, water, and aggregates, such as gravel or crushed stone. Unlike conventional concrete, it is 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.
MARCO has been at the forefront of providing systems to meet this material's handling approach to building concrete infrastructure. MARCO's capability in RCC has been utilized around the world. MARCO's RCC systems are in the United States, Turkey, Angola, Venezuela, Peru, and many others.
