Aluminum anchor bolts is concrete

[jimrcasper]

I need to embed a 1/2" dia. 6061 aluminum alloy threaded rod in an exist concrete slab. The aluminum is necessary due to high intensity RF fields. The appliedloads are small, the bolts are mainly for maintaining a position. Does anyone know of a epoxy that is used and/or certified for this application. Also will an epoxy seperate the concrete and aluminum a sufficent disatnce to prevent a reaction?

I would contact Master Bond and get their slant on your problem. The second website has a lot of leads.
We tackled a similar problem to yours by using an epoxy coating on the Al. I believe the last ones were given a special epoxy powder coating.

This is belt and braces but if you will feel more comfortable it is possible to completely isolate the aluminium threaded rod with glass fibre sleeving.
Contact a local supplier of electrical insulation material and buy a short length of 1/2" plain (untreated) glass sleeve. Coat the rod with epoxy, slide the sleeve over the rod ensuring it is fully impregnated with resin, fill the hole with epoxy and insert the coated rod to a depth of at least 2". Make sure at least 1/2" of sleeve remains proud of the concrete.
The rod will never move and never be affected by moisture in the concrete.
