@meredith You may have trouble with getting this data since being DIY every batch is different. I hope something comes through though. How about a ferrocement outer shell with insulative brick on the inside? That may get you permitting....goodluck

@daniellefiroozi only one way to find out... But generally a "cold joint" is not recommended fit concrete...

@Madeleine slings like a very interesting project. Please contact me. I'm an Earthship Academy student and collaborate With others in this field. I am also a Done Gaia instructor... Contact me at artchemy@yahoo.com Or call (415) 939-5237I have a crew that can help, unless you have people for me to train to build for you...

@vitusthemad no real set formula but we do it like that to fit human scale. The equator at this heigth makes for a dome that allows for more head room Near the walls and ceilings. It would make sense to make a higher equator as the dome size increases. I know that smaller domes use shorter equators to keep bricks from angling too steeply at the base...

@cowra1 there's a workshop most certainly happening there.... Schedule should be out soon.

@Traveler004 Lucky you! I have poured on the light side due to human error and the aircrete collapsed....
There are allot of variables present when pouring, even weather and barometric pressure affects the crete!

@Traveler004 To pass code...Isn't this what we are talking about? I am all for a basalt mesh on the outside of an aircrete dome if you can get it to pass testing, "lie-yers", building department, engineer approval...ect.... to get these to pass we have to look at what has precedence already without having to go through all of the above and Monolithic domes do this.

Domie,
The only way to make it code compliant is to use a structural technique that has been approved and used. If we treat the aircrete dome as "insulation" and not structural- even though it is- maybe there is a way an engineer will stamp it. See ferrocement techniques...

As for 35 feet, I don't see why not. At that width and heigth though you are going to have a harder time heating it. If you are going through with it, I would consider a cantenary dome, it will resist snow loads better, shed water and snow faster, and have less hoop stress. And as for insulation, the thicker the brick, the better insulation. Also, have you thought of applying thermal mass? It helps allot in cold environments. Check out Earthships for their systems of heating and cooling passively, and Earthbags for retaining walls...There is allot to research it seems before you wanna break ground. I am available for consultation, build, or training. Goodluck!

@Traveler004 maybe try wet cutting to keep dust down. Masks and proper gear is important at all times. I haven't gotten any burns from just concrete, I get them from the Milk- concrete bonding agent.

@scottwojo sure you can, but have you checked hempcrete for this application? It's much more ecofreindly process and material.
