as concrete grinding residue (CGR), has a relatively high pH and alkalinity (Goodwin and Roshek, 1992; Druschel et al., 2012). The potential risks of CGR to the adjacent roadside environments result in the various methods of CGR disposal allowed at different locations. In California, CGR is collected and transported to specific containment ponds (Caltrans, 2010). In Utah, CGR is reused as ...

Concrete grinding residue (CGR), or “slurry,” is a byproduct of diamond grinding concrete highways. It is made up of water used to cool blades, hardened cement paste and aggregate particulates. Is Slurry a Problem? Many states limit how much slurry can be discharged along the roadside during the diamond grinding process.
