Concrete grinding diamonds are available in a wide variety of shapes, sizes, and strengths. Size is classified by the mesh or grit number, although a large diamond has a small number (18/20), while a smaller diamond has a larger number (80/100 or 170/200, for example). While larger diamonds are used to expose the aggregate, smaller diamonds

be choked off with a fine-grade material to separate the vapor barrier from the concrete. 5. Avoid overworking the concrete, especially with vibrating screeds, jitterbugs, or bullfloats.

reinforced concrete, the rebar may have many separate areas at different energy levels. Concrete acts as the electrolyte, and the metallic connection is pro-vided by wire ties, chair supports, or the rebar itself. Corrosion is an electrochemical process involving the flow of charges (electrons and ions). Fig. 3
There are also concrete grinding shoes, or redi-lock segments. They aren’t a wheel – but still grind concrete in a similar way. Grain, Grit, and Bond. Grinding wheels are, by nature, abrasive tools. With that said, grit gauges and measures the coarse surfaces of each segment.
