RE: Aluminum conduit in slabs?
It was a pretty common problem with high-rise apartments built in Australia in the 1970s and 1980s – aluminium handrails were cast into the concrete verandas, or bolted directly onto the surface of the slab, and subsequently corroded off at the surface of the slab. I always check out the handrails carefully when staying at a hotel or holiday apartment before I let the kids out onto the veranda.

The code prohibits the use of aluminum in structural concrete unless it is effetively coated or covered. Aluminum reacts with concrete and, in the presence of chloride ions, may also react electrolytically with steel, causing cracking and/or spalling of the concrete. Aluminum electrical conduits present a special problem since stray electric current accelerates the adverse reaction.
