(OP)
I am looking at using a 12" diameter corten A606 steel (weathering steel) tube that will be filled with concrete for some supports on a pier located in a small city pond. The Corten steel shell is only for architectural reasons, I do not need any bond between the two materials. Being that the steel will naturally rust, should I be concerned with the concrete spalling at the interface between the two materials? Has anybody ever grouted a Corten steel column?

The coating works because the oxidation surface is relatively tightly bound to the base metal.

At least that is the literature I have read.
In terms of grouting the inside of the column, the concrete in contact with the steel will protect it, in the same way as it protects an embedded reinforcing bar. So that is not an issue.
