recycled concrete wall

Broken concrete recycled into a wall on a residential street in Albuquerque -- This wall was laid up with some mortar, but it could be laid up dry. The material works really well for retaining walls, also. It's attractive, cheap, and easy to work with (for someone with a strong back).

This particular wall really wasn’t laid up that artfully – the joints aren’t staggered as well as they probably should have been, and it’s not so level – but still, I think it looks good. And it’s certainly functional. And, there’s no shortage of broken-up concrete – readily available.
