How to make AirCrete using the Dragon XL

Aircrete Dome building workshop on Big Island, HI, July 2019, Part 1 - DomeGaia
This video shows how to mix Air Crete using DomeGaia's Dragon XL and how to adjust the foam weight. The next day we cut the Air-Crete into blocks with strings to start building the dome house.

Thanks for posting...doing the interior walls of a Hydraform compressed earth home with these type of walls. Good video and presentation!

[@MyTinyWagon]

Thank you!!!

[@captainamazing1356]

What awesome cooperative teamwork. It would be amazing to be part of projects like this ❤

[@MyTinyWagon]

I highly recommend it!!!

[@RedandAprilOff-Grid]

🙂👍

[@JJ-gc8du]

Great videos. I'm looking at smaller projects (1 bag concrete, not two). What is the target consistency of the aircrete where you know you've injected the right amount of foam into the wet concrete?

[@MyTinyWagon]

They did a lot of testing in the past and figured out the proper consistency. So if you use only one bag, then use half the amount of foam using the same size barrel.

[@yanikivanov]

Soap and cement? Seem super efficient and eco friendly since cement is lime rock and soap we use everyday...i wounder how building companies like lumber tree killers would feel like...o and plastic foam will go bankrupt?

[@utubeape]

at 8:42 when you tipped one drum worth of mixture in it barely came 1/4 up the sides of the mould, but 'next day' was at the top, does it expand by its self?

[@pteepan2708]

Yes, did they add four more barrels or did it expand?

[@MyTinyWagon]

We added 4 more barrels.

Is it possible to pour this product into a form to make walls? Would you still need rebar to reinforce the aircrete? Would using a concrete vibrator to eliminate air pockets have a deleterious effect on the foam?

[@RedandAprilOff-Grid]

As long as it's not too thick, it will settle well into the form. We are going to try to pour our walls. We do plan to use some pretty serious reinforcement. 🙂🏠

[@pteepan2708]

Thanks for your quick replies, do you know how many bricks you made? Any way to figure out cost per brick?

[@MyTinyWagon]

Oh my....I don't know. But I will ask the instructor. Let me get back to you.

[@pteepan2708]

@@MyTinyWagon looks like is was a great time, come teach me your skills in Australia 😁

[@MyTinyWagon]

Oh that would be fun!!!

[@africanpeter2339]

very cool, does anyone know if this stuff is approved by council in australia?

[@the_lion55]

Would there be a difference of pour wet cement in foam instead of foam in wet cement?

[@utubeape]

yes, you would have to lift up a much heavier container

[@MyTinyWagon]

It is a lot lighter to pour soap into concrete

[@mattc9761]

Do you have a issue with cracking? If so, how are you fixing it?

[@MyTinyWagon]

I have not seen much cracking. These dome houses can survive earthquakes. The dome house is covered with a mesh that helps prevent cracks as well.

[@mattc9761]

Is it the polyester reinforcement paper?

[@MyTinyWagon]

Polyester Reinforcing Fabric such as APOC 483

[@pablocasini2]

Hello .. can someone tell me the formula neat and clear please? I can't understand this guy talkings. THANK YOU

[@sarahmae277]

90-100g of foam weight per quart of foam. One 94 pound bag of concrete +6 gallon water in a 50 gallon drum then mix in foam to fill the drum.

[@petersterf6561]

@@sarahmae277 Hi, excelente video...but, 90-100 g per quart....What is the meaning of "quart"..I am not used to this measurement, could you explain what is "quart" in milimeter?...thanks, Peter from Brazil.

[@wahalawatteanandagunathila4861]

How many ml is the measureing cup...

[@BeachBumbiz]

How do they cut the slab into blocks?

[@HergerTheJoyous]

Hand saw will work. A wire saw also work but that take's two people. Or you can build a mold that has a way to divide it before it's cured.

[@pteepan2708]

Wouldn't it be less labour intensive to make molds the size of the bricks?

[@MyTinyWagon]

We used fishing rope. There were slots for the rope before pouring the aircrete. After it hardened we pulled the rope across.

[@MyTinyWagon]

@@pteepan2708 You would need a lot of molds. With 20 people in the workshop we went through blocks fairly quickly. Pouring and cutting didn't take that long at all.

[@StevenfromTX]

@@pteepan2708 cutting the blocks after will counter the effects of shrinkage. She size blocks whether it shrinks or not. I am interested in the fishing rope she mentioned. Not familiar with that.

Are you having a work shop in Los angels

Yes, in June! Check the link: aircretedomeworkshoplosangeles.html

Add some Styrofoam to this mix and you can eyeball work

Music is not needed in most videos and this music makes it annoying as hell to watch. Good info though.
