@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.

@Traveler004 no.I mean to build a basalt or rebar cage outside indenpendent of the #aircrete structure then shoot it with concrete- ferrocement.

@Traveler004 are you weighing your foam? It needs to fall between 90-100 grams

All right Domies, I hear allot of people asking if the aircrete domes meet codes to get a permit. Currently, they do not for various reasons. My thoughts are, what if we follow Monolithic Domes lead on this since they are having success. The two primary materials that I see them using is rebar and shotcrete for structural integrity. They create a steel cage then shoot cement onto a bubble to make a form. Pretty clever. The problems though is cost. They are PRICEY! They still need allot more to finish and end up being the price of the standard "square match box" home. They are prettier, but resource and labor intensive.
Anyways, so why not make an aircrete structure then apply a rebar cage with wire mesh around it and shoot cement? The rebar stubs out of the foundation and ties to the cage. The building department loves rebar and cement...They think it's gods gift! UGH! YUK! But oh well... we gotta get these approved somehow so we can take the next step.

My question to you ALL is, anyone know of an engineer who could calculate and sign off on this? We need a Maverick structural engineer on our Platoon...anyone?

Thanks!

Yes. 90 PSI output from the compressor. The Little Dragon usually is regulated to 60 PSI roughly for good foamage :) You have plenty of air capacity. Goodluck!

@Ignacio-DHOME i don't really understand the second part of the post. Can you take pictures?
