Reclaimed Concrete Material Used as Base or Fill. RCM is most often used as aggregate in a base or subbase course. Although it is generally of high enough quality to be used as base material, RCM can also be used for lesser appliions like embankment or fill material. Since RCM is a crushed material, the angular aggregates will provide ...
