Aluminum pole in Concrete?

Aluminum pole in Concrete?

Aluminum pole in Concrete?

(OP)
Do standard Aluminum structural shapes/alloys have a problem (chemical) with being embedded in concrete?

Thank you,
SeattleMike

RE: Aluminum pole in Concrete?

The aluminum should have an asphaltic coating or some other way to electrochemically separate the two materials.

Hi UcfSE,

Is there a difference between "asphaltic" coating and "bituminous" coating?

RE: Aluminum pole in Concrete?

Not only is concrete not good for aluminum, aluminum is not good for the concrete.  Concrete codes prohibit embedded aluminum.

RE: Aluminum pole in Concrete?

Black electrical tape wrapped one layer thick with a small over-lap has been used by me for years. Also, make sure that water cannot fill the embedded post, I have had split posts and split concrete due to freezing. Years ago I had a commercial AM antenna (Lingo pole) split vertically for about 40-feet.
