Today, specifications for polished concrete are now including specified gloss readings, determined using gloss meters (see table). Gloss values express the degree of reflection when light hits the concrete floor surface, and range from 20 to 30 (low gloss) to 70 to 80 (high gloss).
Concrete diamond grinding removes roadway imperfections caused by construction and/or heavy usage. The immediate result is an improvement in pavement smoothness, surface texture, skid resistance, safety, and noise reduction. This service can also be applied to asphalt pavement. Advantages of diamond grinding over other rehabilitation techniques:
For instance, portland cements and blended hydraulic cements for concrete in the U.S. conform to the American Society for Testing and Materials (ASTM) C150 (Standard Specification for Portland Cement), C595 (Standard Specification for Blended Hydraulic Cement) or C1157 (Performance Specification for Hydraulic Cements).
Diamond grinding generally reduces slab thickness by 4 to 6 mm ( 3 16 to ¼ in). Since slab thickness is one of the most sensitive factors affecting cracking performance of concrete pavements, any reduction can be a concern. A cracking model was used to determine the fatigue life of jointed plain concrete pavement (Rao, Yu, Darter).

With the concrete sound and contaminant-free, all that's left is to adequately roughen the surface, but to what degree? The blasted concrete surface is too rough to be measured by tape and quantified in microns or mils. The most effective reference tool for determining concrete surface profiles is the molded rubber comparator chips, available from the International Concrete …
The grind and seal process is a combination of preparing the surface, grinding the concrete smooth, repairing in cracks or holes, and cleaning the surface, and then sealing or installing a coating on top. It is important the concrete is prepped properly, so that the sealer or coating can adhere to the surface.
Polished Concrete project cost can vary widely based on factors including concrete condition, job size and location, aggregate exposure, gross level and coloring selection etc. For a fairly smooth floor, that requires only a few levels of grinding, $3 sq. ft. is the basic cost for a polished concrete floor.

Diamond grinding is one of the most cost effective concrete pavement restoration (CPR) techniques. It consists of "grinding" 3/16 to 1/4 inch (5 to 7 mm) of the surface of jointed plain concrete pavement (JPCP) using closely spaced diamond saw blades. The result is a level, smooth, and generally quieter riding surface.
