We have just finished pouring the concrete footings for our home. 3/4″ agg with a 3 slump. Several steps show only minor honeycombing ( <1″ deep on the surface of a 1 1/2′ thick step). My major concern is some honey combing on the continuous footing at the garage entry. There was a lot of rebar in the 18″x8″ footing, and I have a few spots where the rebar is exposed on the side. One is about a 5″ side exposure tow others are just the ends of the bar.
What is a good fix?
Reform around these spots by 6″ or a foot and repour a higher slump mix?
Is there some type of patching media that will keep the rebar isolated from moisture?

With a footing in ground, you are not going to stop moisture from getting to the rebar.
it is the combination of oxygen and water that will rust it.
patch with mortar mix or better - Thorocrete and then you could add the emulsified tar for good measure.

A good fix is to go kick the #### of the person who did the work and don't pay him. To have exposed re-bar and honey-comb on a simple footing and stair is unacceptable.
Hard to kick himself.

Undergound, probably not getting a lot of oxygen, at least according to the buried alive horror movies I've seen<g>
If you can see 'em, you could slather on some epoxie...if you're going to repour, be sure the new projection isn't more than the thickness of the footing, if you're working to the IRC.
Don't worry, we can fix that later!
