Concrete Grinding Residue: Management Practices and

Concrete grinding residue (CGR) is a slurry byproduct produced from diamond grinding operations used to smooth concrete pavement surface. As a waste material, CGR consists of cooling water for blades and concrete fines from the removed concrete layer. Since the composition of CGR reflects high pH, it can be a critical environmental issue and should be managed properly to reduce its impact to ...

[PDF] Evaluation of Concrete Grinding Residue (CGR)

Diamond grinding is a concrete pavement restoration technique that corrects irregularities such as faulting and roughness on old concrete pavements and extends the life of pavement. Cooling water used during the diamond grinding of concrete pavement highways generates slurry consisting of water, concrete and aggregate residue (CGR). Recently, disposal of CGR in Nebraska changed from ...

Is Slurry an Ugly Word? - Roads Bridges

This byproduct, concrete grinding residue (CGR), is commonly called slurry. How CGR is handled varies greatly across the country. In some regions, it is spread along adjacent slopes as the saw cutting or grinding operation moves down the roadway. Other times, and in all areas with closed drainage systems, CGR is collected and hauled to off-site locations for processing and disposal. Engineers ...
