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.
