Created by replacing sand with rubber particles when mixing concrete, the material promises to significantly reduce certain environmental impacts, yet its structural properties are still relatively unexplored. A certain diversity for the cr application can be introduced in a more efficient way when surface treatment and concrete mix design optimization are properly developed for each type of cr application in concrete for possible field applications. Crumbed rubber concrete (crc) is a promising new material on the construction scene.
