There are many tools that can be used to smooth concrete, organized by size, the first is a concrete surfacer/ edger, used to edge the sides of a slab, or smooth over rough edges of a protruding slab, the secondly is a single head concrete grinder, used to either grind or polish concrete in areas below 8m2. The third tool for smoothing concrete is a large 3-head planetary concrete grinder, which is the industrialized version of the small concrete grinder, appropriate for sizing above 80m2. Finally, if you are looking to remove a large amount of volume, a concrete scarifier is best, which utilizes hardened spinning rods to plain down the concrete in layers.
