I just joined this site and I'm stoked! Content/community looks great. We are looking to reterrace a steep slope next to the entry of our land sanctuary, and we will be installing a native landscape on the hillside. Our entry building is the first permitted straw-bale building in Ventura county (built a few decades ago), complete with a fly-ash foundation and bluejean insulation, and I thought it would be a sweet gesture to continue the legacy by constructing the terraces out of recycled concrete slab. Does any one know where to go to find broken up sidewalk? Do I go to the dump? Or just drive around til I see a demolition project? We're based out of Ojai, CA.
Just go on Craigslist and post a wanted ad. Broken concrete is undesirable material; trash haulers don't want it (overloads the bins), landfills don't want it. If you are willing to take it and recycle it, you can be saving somebody a lot of headache.
Keeping your eyes open for construction projects can actually be really fruitful. Otherwise, you might search yellow pages for demolition contractors, tell them you're looking for broken up sidewalk or other slabs of concrete without rebar (unreinforced).

Peter - There are lots of sources but not all of them will be usable. The best sources are from slabs that did not have remesh or rebar placed in the fresh concrete. If the urbanite contains remesh or rebar it'll be to dangerous and difficult to work with. Look for older patios, driveways, basketball and tennis courts and sidewalks that are being demolished. A lot of the older stuff has no remesh and is a pleasure to work with. Another good source are municipal jurisdictions. They often have graveyards where they dump this kind of material and they usually let you pick it up for free. You might want to watch my Urbanite! video to get some ideas - www.vimeo.com/channels/erdakroftfarm
