A small planetary concrete grinder with basic grinding tools will remove around 1/16” of the concrete in 1-2 passes in a normal situation. You might be able to remove more – 1/8’’ if use a heavier concrete grinder and more aggressive PCD tools. In fact, an angle grinder with a cup wheel will do the best job.

It will be easier to grind in the case of soft concrete, especially if you use highly aggressive PCD tools for concrete layer removals like glue, black mastic, or other imperfections.
