Epoxy covered rebar exists as does one made from stainless steel. It’s just quite pricey so it’s rarely used unless absolutely necessary. Rust is generally not an issue as long as the rebar is deep inside the concrete. When it’s close to the surface and gets exposed to elements is when the problems start.
Isn’t titanium too rigid for this application though? I’ve worked with both for a mechanical application, and titanium has no flex, so stresses get passed in to other components.
I don’t know, I’m no civil engineer. Any civvies wanna fill us in?
the iron is a great way to increase tensile strength, but decreases lifespan, rust free metals would also be much nore expensive.

Wdym? Just replace the iron rebar with gold
Gold is no where near strong enough.
Titanium would work just as well, and last quite a bit longer.

That could be. Maybe some alloy? Not sure
