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.



  • Ooh. We have long-term plans for our new property, and a half-buried (with tires) low-grade geothermal air greenhouse is definitely on that plan. Excited to think this would be a good (faster/easier) option!

    I wonder if this system would work above ground as a perimeter wall? I have access to lots of used tires and I'd love a round building with a wooden reciprocal roof. Course, we could just build it with upright post supports and aircrete in/around, but I like the idea of using garbage and not having to pay for new commercial lumber.



  • Only thought is dirt is free; Aircrete, tho less labor has a cost.
    you have to weigh labor vis cost.



  • I found this by searching for "aircrete tire" because I had the same idea.

    The advantage is that one can fill the tires, let them cure in a ground level staging area. Then you roll them along to where they are needed. The weight and cost would depend on how light the aircrete that you could make.



  • I like the innovative thinking of all the posters. One of us or another "thinker" will find an even better solution to whatever problem comes up.
    On the Air-Crete for tires I had another thought. Pounding the tires with dirt actually swell up the tire in place and helps lock in place. Not filling the tires in place and stacking them would negate that aspect of structural integrity. May or may not be important depending on design of project.
