CONCRETE GRINDING RESIDUE (AKA SLURRY)

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.

Concrete grinding residue characterization and influence

Concrete grinding residue (CGR) is a slurry byproduct created by concrete pavement maintenance operations. Disposal of CGR slurry is presently regulated on the basis of very minimal information. The least immediate expense is incurred by spreading CGR slurry directly on vegetated roadway ditches and embankments.

Disposal of Concrete Grinding Residue Modern

Jan 15, 2014 January 15, 2014 An area of focus within the construction industry throughout the past few years has been the question of how to handle concrete grinding residue (CGR), also known as sawing slurry. Generated during sawing and diamond grinding operations, slurry is the byproduct created when a diamond blade’s cooling water mixes with concrete fines.

Concrete Grinding Residue Doesn’t Appear to Negatively

Aug 20, 2019 Vacuum lines then collect the residual dust and rinsing fluids, generating a slurry of concrete grinding residue (CGR) that is frequently discarded on roadside slopes and vegetation. When slurry dries, it leaves pale gray patches on roadside vegetation and other features, lightening the soil surface for a season or more.

A Greenhouse Study of Concrete Grinding Residue

May 16, 2020 Concrete grinding residue (CGR) is a slurry-type byproduct of diamond grinding containing concrete particles mixed with water (Goodwin and Roshek 1992; Druschel et al. 2012 ). CGR waste treatments vary among states, but in the Midwestern US region, it is common to directly deposit CGR along roadsides.
