Using AirCrete as a filler for tires on a tire wall (Reynolds earthship)
Would aircrew work as a tire filler rather than earth rammed tires on wall that would be earth berm as in Reynolds earthship homes. It no doubt wouldn't expand the tires and they wouldn't end up weighing 300 lbs each but wonder if it would be strong enough to hold up against earth berm on three sides. I expect the lite weight would make it unsuitable but just wondering if it would work.
It would be a lot easier and plenty strong
, but you wouldnt' have the thermal mass.
