Re-bar
So I think it's probably accepted that one doesn't want metal inside of a structure, particularly within a concrete part of it such as foundations or walls in icf, to rust, correct?
well in that case why is it that whenever i see a picture of rebar, be it panels or cage, it has a ayer of rust on it, and this is what goes in the concrete. Will this not rust inside the concrete? Also, those little plastic stands one puts underneath to keep the bar away from the insulation/ground undern
I was concerned about the long-term durability of standard steel rebar, so looked into alternatives a bit. My layperson's summary below.
However, I'm now just going to use standard steel in our own Reinforced Concrete parts. While steel corrosion seems a major problem for structures like bridges, dams, etc, my SE has assured me any RC with standard rebar kept protected from; the elements, unusual chemicals, and cyclical loading should be fine for over 150 years. I.e. ours will be fine,
