Anyone ever thought of using the debris from demolitions (old concrete, etc) when pouring slipforms? Think it would be worth the time/effort?
Set up the slipforms.
Drop in big chunks of concrete where they'll fit.
Pour the 'crete around 'em, locking them in place.
Could conceivably cut the amount of 'crete needed by a fairly sizable amount...and at least in some places, the "demo" junk is just waiting to be hauled off.
Thoughts?
