The rust will continue to build up on the rebar in the concrete, as it builds up it will expand eventually cracking the concrete. Not sure where you live in Maryland, but have you ever seen exposed rebar in a semi-tropical or tropical environment? Wherever it's been exposed to salty sea air, the rebar does not last long at all. Or even rebar in a bridge deck or column that's been exposed to salt for clearing roads. Yes, the salt does a lot of the damage, but you are already starting with rebar that's been compromised.Talk to an experienced concrete contractor and get his opinion. If it was me, I don't think I'd do it. Rebar is not that expensive compared to the cost of the concrete you're trying to pour.</blockquote>
