Idiotproof aircrete

NightHawkInLight continues to amaze:

Perfect Aircrete, Kitchen Ingredients.

It looks like any large quantity would take a lot of Dawn detergent.

While he makes aircrete blocks; I could see hexagonal tiles of varying proportions, plus a few pentagons. With a few hundred tiles you could make a whole house.

As we know from the BA thread; that DOES NOT FLY here!

Someone is bound to jump out from behind A Google Email Alert And take A giant dump in your Aircrete!

Jokes aside; good find!!
I wonder if one could paint one (or 2) side/s the mold with a limestone dust/whitewash to get that Solar Paint effect? If it's even worth it if the brick is so insulating?

It's Youtube. All the demos I saw weren't long enough to get all the aircrete hot enough to not hold onto bare handed. Regular not enhanced takes a small while to spread heat I would suspect aircrete to take much longer stilll so it's kinda wasted energy to white coat it. Would look better possibly some waterproofing, but........

Still gets to you? I'm the same about Mud Bubbles.

It occurs to me that a mold release would help. Maybe a teflon/PTFE lining. Anything made from blocks probably needs a layer of plaster after assembly.

I went to post this in my Shavingrete thread, but wrote about graduating, applying and interviewing, but not being offered a job (well, once), and struggling to study for the Praxis, which I take Saturday morning.
I finally decided to just study for the Praxis.
After driving Mom and my brother around all day, I was finally starting to study, when I remembered the video.
I was going to cut and paste the personal stuff elsewhere and just share the video.

If anyone hasn't watched the video, the secret ingredient was Xanthan gum, but he couldn't get that to work until he mixed it with alcohol, because normally the gum clumps.

Have I mentioned anywhere that I graduated?

Thanks for posting. I'm still hoping to hear from aerohead (sorry Logic).

I started this new thread, but didn't think to appended to yours. IIRC it involved shaving cream. Another grocery store item.

I also graduated; but instead of getting a job I went off to the one-time Republic of South Vietnam. It was ten years before I got a job that was in the field of architecture/landscape architecture (Oregon Dome) but it was a startup run by -- shall we say -- small minded people. They were suspicious of what I might be doing with the money they paid me and ran me off. The only thing that saved me was the personal computer came along in 1980. They would hire anyone that could do the work.

Youtube is showing me a lot of octagon house videos. The best one is an hour long, this drops you in at 4:01: "The Armour-Stiner (Octagon) House" I think Armour-Stiner is my favorite house, I'd never seen the interior before.

When I was in college and they said design yourself a house, mine always had an observatory (for sunsets). Armour-Stiner has one at the top of that spiral staircase. And statutes of hot chicks in the garden.

Back on topic -- imagine this built out of aircrete?

[freebeard]

On watching it again, I see that at 23:14 it shows how an original two-story house (the Armour house) had three additional stories and the encircling porch added twelve years later.

Regarding aerohead: did he leave voluntary or got booted? think the latter because of a war with hitherto unnamed participants still here.
Makes a difference on ability to reply.
Other than foot thick ground floor walls and a personal inability to build the dome freehand, like your line of thought. Hmmm many wall balloon would work

My concern is that he read a post, clutched his chest and fell over.

Wall balloon?

Foot thick walls could have a dense skin with air filled interior, but the problem I think you're getting at is the base spreading. That is traditionally prevented with a compression ring girdle (like a yurt), or Gothic flying buttresses.

OTOH a greater than hemisphere dome will press inward on it's foundation.

a personal inability to build the dome freehand

Not sure here. Your own limitation or something generic? Freehand sounds like make a giant sand castle, pour aircrete over it, and wash the sand out.

Here's another video:

Why isn’t this patented yet? The CEMENT MIX that shocked NASA and the Chinese

Clickbait title, but it suggests used motor oil as a mold release.

The final demonstration reminds me of the concrete canoe races.

ASCE Concrete Canoe Competition
This elite competition combining engineering excellence, hydrodynamic design, and racing technique is known as the "America's Cup of Civil Engineering." The ASCE Concrete Canoe Competition was made possible with funding from the ASCE Foundation.
