Galvy in Concrete Was:aluminum in concrete [RE-wrenches]

[William Miller]

Friends:

I've noticed that one tracker manufacturer or another recommends a section
of re-bar through the bottom of a pipe mast. I always assumed this was
intended to keep the mast from loosening in the concrete and rotating under
heavy wind loads.   Is this possible?  If I sleeve my masts, or wrap them
in foam sheets or vinyl, are they more likely to rotate?  Should I cap the
bottom of the pipe so no concrete to steel contact is posssible?

(These are rhetorical questions.  There would have to be strong evidence of
a problem before I would change practices that are tried and true, not just
by myself, but apparently by many others on this list.  I feel that
galvanized steel in concrete is a good practice.  I've seen it extensively
in RE and communications for structural uses.)
