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...Tire recycling centers, for instance, may simply ship their shredded output to other facilities for separation, re-shredding and grinding. If so, a single-pass shredder or shredders will probably suit their needs and will probably cost less.

Compressive strength of recycled aggregate concrete with vibrations of 30, 60, and 90 seconds increases 21.1%, 22.1%, and 22.6% sequentially correlated to normal concrete. Recycled concrete using heating and grinding methods with the addition of vibration during the mixing process is effective to be used as an alternative to normal coarse ...With the most advanced cutting system, Advanced Recycling Equipment, Inc. has become a technology leader.

The use of recycled aggregate (RA) generated from construction and demolition (C&D) 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...To use recycled concrete as aggregate for concrete contaminants like reinforcing, steel foundation, materials soil etc are removed from the concrete debris. It can be done by screening, air-separation, demolition using electromagnets. Then the debris is crushed either manually or mechanically.

Crushing concrete allows us to produce our own DOT Certified RCA (Recycled Concrete Aggregate), a highly compactable base material.
