There was one researcher who got a paper published in the JBIS which said
that the aluminum approach might be an example of "aerospace thinking", and
that if the goal is a permanent habitat rather than a space ship that cement
might be a more sensible material selection. (Although what he was actually
talking about was closer to cast basalt with rebar.) His argument was that
after having built the pressure vessel out of aluminum, you have to slap a
layer of slag on the outside about equal to the mass of a concrete wall over
a yard thick anyway just for radiation protection, so you might as well
build the pressure vessel out of such material and save the bother.
