Concrete grinding is the process of smoothing rough concrete surfaces. During the concrete grinding process, an abrasive tool with diamond attachment smooths the rough surface. All coatings, stains, and surface cracks are removed along with the top layer of concrete during the first step in the process. Deeper cracks must be evaluated.

Water is used in the process to cool the grinding wheel, decrease dust generation, and facilitate removal of the concrete grinding residue (CGR). CGR cannot be allowed to simply flow from the road surface to the adjacent environment, and is typically picked up by a vacuum truck, or sweeper truck, which follows the grinding equipment [ 6 ].

equipment are washed out, a process which requires up to 64 gallons of water per cubic yard of waste concrete (Geem et al. 1998). After hardening, construction procedures such as joint saw cutting and diamond grooving, as well as maintenance procedures such as diamond grinding, also require water to control dust and to cool the saw blades.

Concrete floor grinders are used for grinding the concrete and are fitted with different diamond grit abrasives. The grit level is increased the coarser they are (30, 50 and 80 grit discs to the finer 100, 400 and 800 grit discs). The grit level can be increased up to 3000 grit discs for providing ultra-swank luster to concrete.
