I used my big angle grinder with a heavy grit concrete grinding disc to smooth out the top of the casting. This began to expose the plastic. When the surface was smooth, I switched to a rubber backer disc and sandpaper. I started with 120 grit, went to 150 and finished with 240 grit. This gave a smooth, semi-reflective surface.
Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill.

In recent years, the CO 2 curing technique has been developed to enhance the properties of recycled aggregate (RA) and recycled aggregate concrete (RAC), materials that can absorb the CO 2 gas and are more sustainable for the construction industry. A body of literature on the CO 2 curing of RA and RAC is currently available, but a systematic review is lacking.
Crushing concrete allows us to produce our own DOT Certified RCA (Recycled Concrete Aggregate), a highly compactable base material.

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 . The use of recycled aggregate in new concrete requires a beneficiation process, which separates the natural aggregate from the attached cement paste/mortar.
