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.
Mar 05, 2021 The soaking of RA in mild acetic acid and mechanical grinding are two essential techniques identified in the literature, which significantly enhanced the RA properties. A portion of adherent mortar remains attached to the recycled aggregate, a thin, more brittle, and cracky layer after old concrete has been crushed.
This means reducing, reusing, and recycling most if not all materials that remain after a construction or renovation project. Green building construction practices can include salvaging dimensional lumber from the project, using aggregates reclaimed from crushed concrete, or grinding drywall scraps for use on site as a soil amendment.

Apr 29, 2020 When concrete waste is crushed, a certain amount of pastemortar 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 pastemortar.
The use of recycled aggregate RA generated from construction and demolition CampD waste to produce new concrete would minimize the need for the use of natural aggregate NA. The authors propose a new hybrid method in the present work by combining presoaking in mild acetic acid followed by mechanical grinding to produce high-quality RA.
