Rebuilding with Recycled Concrete
Now, after five years of weather and use, the recycled concrete has proven that it can perform as well as new concrete and often better. Not only that, but the recycled concrete can be recycled again and used a second and third time without its target strength being compromised, although the rate of strength gain is less with each use.
