Rebar

[Not db4600]

I’ve seen a lot of concrete demoed and don’t necessarily agree with “any”. Seen plenty of mesh, bar, and embeds that are still in good shape. Granted there are plenty of instances where it is not in good shape. If it is incased and sealed it should be ok.
Where it comes to is exposed to moisture or salt it makes sense.
In 94 I was in the Whitefish Bridge. Sub grade foundation and bridge deck were epoxy. The vertical structure were not epoxy.

Currently on an Armory. Subgrade foundation and above grade vault are not epoxy. All CMU reinforcement is not epoxy. 8” civil paving is not epoxy. Mechanical mezzanine wire mesh is not epoxy on galvanized pour deck. The maintenance garage and aprons are epoxy.

Tomorrow when then excavator starts demoing the existing civil paving he might wish it had rusted away.

Non epoxy rebar. 40+ years old. Site lot of the Armory.
