Air Crete Dome Homes – Video



Nothing to do with the coming ice age, but I find this concept fascinating.



Commenting on youtube, Mark Soares thinks Foam Cement is “the BEST building material in the world.”

“It is an ultra light masonry product weighing only 1/5 of the weight of ordinary concrete,” says Soares. “It is composed of 1 part water, 1 part cement (which is powdered or ground limestone), 1 part non toxic dish soap. The detergent is foamed using air from a compressor and a pump or motor to agitate the mixture (I use a conventional drill and paint mixer to blend it all together and it works fine). The expansion of trapped materials results in ”air” or oxygen molecules which comprise the majority of the material (I believe close to 80%) upon expansion.”

Soares adds that “it’s fire proof, water proof, insulating, bulletproof, earthquake proof, hurricane and monsoon proof, impervious to insects, rodents provides acoustic insulation and is 100% free of toxic of harmful substances, which makes it 100% biodegradable and completely recyclable. It is all natural and produces no by products. Also, as if it weren’t’ enough, it won’t rot, rust, corrode, warp under cold or heat or otherwise decompose in at least 30 years for my home so far.”

  1. nifty isnt it?
    glad you liked it Robert
    hope it gives others some ideas as well
    after looking at this clip I found a Japanese company making some really good ones also
    they get a bit same same..but then
    you can add change enlarge and make variants.
    Id like to have a go making a stable for my horse, and reckon an old tank will make a decent size support and nice rounded shape as a trial version.

    • They look cool, but how would they do in an ice age? They seem to be more suited to a warm climate.

  2. Ever try to put a sofa along a round wall?

    At UC Davis in the 70s they made a bunch of fiberglass dome homes. Don’t put the smoke detector at the very top or everytime you cook it goes off… I think it was called Baggins End?

    Other than those two things they worked pretty well.

    Ferrocement domes do well too.

    Foamed cement without rebar? Ummm….

    • Would depend on structural integrity needs as to whether or not steel rebar is necessary. In certain applications, yes—but as a poured product, it would be easy to incorporate rebar into the finished structure.

      Given that it reportedly has the same structural density as wood, structural rebar isn’t even necessary, especially as a full wall. Straw bale construction uses limited rebar or posts in construction and instead relies on the tightly-bound and parallel structure of the straw itself for structural integrity.

    • thats why they use the arches to gain flat spots;-)
      and plenty of foamed crete standard homes n large buildings without rebar in Aus.

  3. I’m a bit puzzled, how can it be biodegradable if it doesn’t “rot, rust, corrode, warp under cold or heat or otherwise decompose in at least 30 years ”

    To be that is as near permanent as it’s possible to get.

    • you could put it into a crusher and turn it into rubble/chips for further use as paving stone or landfill etc with no harm to environment, or go all out n turn it back to powder;-)

  4. Thanks Robert for posting. That is an amazing material. Have always been looking at alternative building products, and this beats them all by a long shot.

    • first you have to get TO the moon;-) lol
      water is there i gather but not much/hard to get to.
      of course the ??H30 or something like that fuel source ON moon would make extraction of it easier. and would have provided fuel to earth and for then boosting outwards to Mars n stars
      and if we ever did get to the moon, and I AM sceptical of that, then why the hell they didnt make a base there decades ago instead of the highly at risk floating tincan spacestations?? when the same fuel would have got them lunar.

  5. this looks very interesting. I am not a fan of the domes but the product could be made into bricks for more conventional builds. Might be very useful in earthquake zones.

    • we use a version commercially for housing bricks n slabs in Aus
      Hebel is the brand name
      of course the commercialised versions cost almost as much as kin bricks do here.

  6. Aircrete are not dense enough. Will not meet codes. Not Safe enough. For dome homes see MONOLITHIC DOME HOMES. One church paid for itself after 6 years from savings in electricity!
    http://www.monolithic.org/

    NOTE: NEVER do geodesic domes except for plants. The straight lines / angles increase emotions – increase divorce rate. But great for making plants grow!

  7. Looks like the R-value of it is around 1/2 of fiberglass batt insulation, so your wall thickness with aircrete would have to be around double. BUT you would still save a lot on siding, drywall, etc. Looks pretty promising for a lot of different applications

  8. There is no logical reason why a house should be box shaped. The dome takes its inspiration from the igloo LOL, that in itself the best form of housing during an ice age. And have you seen the ice hotels in places like Sweden?
    I also admired the Teletubbies’ house, a grass covered dome with windmill in background for alternative energy and the beaming sun in the sky. I suggest coating the house with solar panels not grass LOL. Then very extensive garden with an abundance of bunny rabbits, flowers and activities for all.
    These new construction ideas need further investment and growth.

  9. Water proof? Can it be used to make boat hulls, maybe a cheap fiberglass substitute? Make your own floating island???

  10. we used a form of aerated concrete for a set of floating floors in a recording studio – weight was the main concern – so we had to double the thickness to achieve the right mass for absorption and isolation and it was still only maybe 1/3 the weight of using regular concrete. very cool stuff. it should be amazing to see how graphene and other materials as additives improve the structural strength and weight…
