Where do you guys find cinder block? I haven't seen one for over 50 years!

Sorry, but that's an old wives tale. Concrete itself is porous as hell and
will pass moisture almost as easily as any cinder block. There is no way on
this earth that concrete will keep moisture away from the iron, but the
alkalinity of the concrete will indeed keep the iron from rusting and that's
why our bridges hold together and our towers don't fall over.
