Post tension anchors? For what? That looks more like 50 years old than 1. I suppose it could be the ends of rebars. Can you take a wider view photo?
I can take a wider view. my point in asking is, after the foundation is tensioned, they go around and cover the exposed end of the tendons with a patch of concrete or something else so the end of the tendon is not exposed. I was wondering if the two pieces of metal on either side of that patch need to be covered as well? this website MAY have answered my question as to what those are. looks like those were the nails that held the anchor to the form boards. I just want to make sure I don't' need to cover those rusty ends that are exposed to the elements. https://profengineering.com/exposed-tendon-anchors-repair-them/
Yes, they should be covered but first, you'll need to get them to bright metal and then put a non-masonry parge over them.
Nice photos
You have to get them repaired to prevent the failure of the reinforcement for your foundation.
