There will be a problem with water infiltration at the point that the rebar projects from the concrete. Freeze-thaw cycles will certainly be an issue at some point. Also, the surface rust on the bar will have to be removed before any future concrete could be poured. At the moment I would guess the bar hasn’t degraded enough but with the climate of Chicago I would count on an engineer not signing off on his work in the future if we see this drag out.
