Heavy metals are present in concrete grinding residue, but concentrations are of the same magnitude as typically recycled concrete residuals. The chemical composition of concrete grinding residue makes it a useful product for some soil amendment purposes at appropriate land application rates.

Concrete can be recycled by grinding it up, then using screens to separate fine and coarse materials, magnets to remove steel, and water floatation to remove other unwanted materials. It can then be used to form hardcore sub-bases underneath new structures, gravel for paths or driveways, or even act as the aggregate for new concrete.

When concrete waste is crushed, a certain amount of paste/mortar from the original cement mortar remains attached to the aggregate particles, which forms a weak, porous and cracky layer [ 2 ]. The use of recycled aggregate in new concrete requires a beneficiation process, which separates the natural aggregate from the attached cement paste/mortar.
