The adhesive used in asphalt is tar and the adhesive used in concrete is cement.
Because grinders use rotary action rather than impact to remove material, the depth of material removal is limited to about 1/8 inch, depending on the type of attachment used. They generally leave behind a smoother profile than scarifying or shotblasting, and when working on hard, dense concrete they may polish rather than abrade the surface.
