It was around 8" thick, and I rented a 60# electric demo hammer.  It took a few one hour sessions to get it done (it vibrated the bejesus out of your wrists and forearms).  It won't make much difference what the mix was.  I'm guessing you should have it done in a half hour or so.


Demo'ing a slab and a big block are VERY different.  With a slab, once 
you get it cracking, it's easy to propagate the cracks and keep chunks 
coming off.  But breaking up something like a 3 foot diameter lump is a 
LOT harder.

Zapping out an old patio is the work of less than a day (at least for 
the breaking it up part.. hauling away the residue in a wheel barrow, 
etc. takes almost as long, if not longer).
