Pros and Cons of Recycling Concrete - Decomposed

2021-4-22  Concrete recycling is a staple part of the construction industry. Concrete is basically a fusion of different elements including gravel and sand. Once these elements are mixed, they are bonded together using water and cement. But then, what happens when houses, walls, are demolished? Where does all the rubble go to? Should we assume there no longer usable?
