Q&A: Basics of recycled concrete
Recycled aggregate is waste material from demolished buildings or bridges, for example. When demolishing such structures, the waste needs to be sorted into wood, glass, etc. and concrete. This is called selective demolition, as the structure isn’t knocked down as a whole, but the materials are taken down selectively.

Ways to Recycle and Reuse Concrete
Concrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate. Additional processes and equipment, such as water flotation, separators, and magnets, may also be used to remove specific

How to Crush Concrete for Recycling
After cleaning and sorting, you can load the concrete up and haul it to a concrete recycling plant for processing. Alternatively, you can handle concrete crushing on-site. There are a few different options available for crushing equipment in terms of size and how fast they operate. A sizeable road-portable plant can process 600 tons of concrete and asphalt per hour, but it’s a large machine
