He already did permanent damage by putting bleach on 3 day old
concrete. The surface will probably deteriorate and flake off where
the bleach was used.
The best solution at this point would be to rip it up and pour new
concrete.

I see absolutely no reason why bleach would harm concrete any more than water would.

Bill: If the concrete wasn't damaged by the bleach already, and you rinsed the bleach off with WATER, and that water didn't do any harm either, then neither one did any harm to your concrete.
