Roller-Compacted Concrete (RCC)-old - Cement
A water cure sprays or irrigates the pavement to keep it moist. A spray-on membrane can also be used to seal moisture inside. When appearance is important, joints can be saw cut into the RCC to control crack location. If economy outweighs appearance, the RCC is allowed to crack naturally. Once cured, the pavement is ready for use.
