Some of the engineering properties that are of particular interest when RCM is used in Portland cement concrete applications include gradation, particle shape, specific gravity, absorption, moisture content, durability, and permeability.
Dry grinding creates huge amounts of dust, while wet grinding produces huge amounts of water and slurry. Honing (50grit to 200grit) is much faster when done with water, which flushes the cuttings, improving surface finish as well as the tool's life span.

Grinding opens the pores in the concrete, which helps the epoxy have something to grip, creating a better adherence. A shot blaster can do this, too, but can create a pitted, uneven surface.
Magnesium phosphate cement materials are formed by reacting magnesium oxide with watersoluble phosphates such as monoammonium dihydrogen phosphate (ADP), which solidifies at ambient temperature through the formation of hydrated phases in the material.
