Proof of concept test was a partial success!

I have a 12 v pack of Nissan Leaf automotive cells...
These are wired 2s2p for 16volt and 100 aHr .

The whole house filter is stuffed with ss wool pads. My foam was heavy at about 300g/L
House Filter

That was with 50psi air pressure. I think I need to stuff more ss pads into it

The pump is a Johnson 28watt 12volt sealess 22.5L/min
It fits perfectly at the bottom when you put the 2 buckets together.

I found this you tube of one built I think near Vancouver BC... Enjoy

I think a pool liner would work well, but not sure if the polyclothe mortar layer is enough to hold the aircrete together when the pool is full of water.... that's an enormous amount of weight and pressure.

I just purchsed a home and will be moving soon. There is a jacuzzi in the backyard that I think I will insulate around the bottom with aircrete by spraying it in with a texture gun. That wont be for support, only for insulating.

Would a router work for quick channel cut outs? Then re-finish it with another layer of polyclothe.

Why not use a texture gun with hopper and spray a sticky mortar layer where the new pour joins? I was thinking of using this technique to apply the final cloth layer.

what does adding antifreeze do?

@Leonidas I like all these ideas. I am feeling that the rebar is a little bit over engineering though. The bricks are brittle and think that maybe applying a rigid material like rebar will: one, make it difficult in applying, and two, create such a rigid structure that the bricks will be compromised tremendously if there is an earthquake. I love the basalt mesh idea. To me, with this, it will be plenty strong along with the structural integrity of the dome shape itself to resist falling and breaking off. Making something to resist the forces of nature I feel is a fallacy in engineering that is changing. Harmonizing with movement and the natural integrity of natures forms is the way to go. My two cents...you ARE the the engineer though and it will be you and your family inside:)

Wise words my friend:)

I want to say a bottom wall to waste level would be fine just not as much aesthetic appeal, maybe, and more floor area to tile and keep clean. I like the idea if its burmed on the outside, or into a hilltop, but you have to think about rain runoff. I was dreaming of a rain catch where three domes intersect. run it into one of the domes and have an indoor waterfall and green room... fresh filtered rainwater pool

Then the shipping container can be re-used or kept on site for storage, or converted to another living space.

This is interesting. I was thinking of a modified compass center pole design using 4 arms. At the end of each arm would be attached a 1 meter x 1 meter mold to inject the aircrete into, or pour it in from the top of the mold. After the aircrete sets for a day or 2, all 4 of the molds can be moved to the next adjacent position. Row by row moving up vertically.
My other thought was to make the mold stationary and pre-make the blocks to assemble with mortar. All the blocks could be theoretically identical, because the structure is spherical. They may have to be cut as the rows move upwards.
This would be cool because all of the blocks could be pre-made and packed into a shipping container and delivered to anywhere in the world. Like a dome kit in a box, some assembly required!!

Here is a link to basalt mesh...basalt mesh
I live in an area that may experience a huge devastating earth quake thats long overdue. I was thinking if the mesh is used on the interior, it would prevent any big chunks from falling in.
