@zander - I decided to order one pound of powdered Sodium Lauryl Sulfate (SLS) from Amazon which cost $15.75 including shipping. (https://www.amazon.com/gp/product/B00HX47342/ref=od_aui_detailpages00?ie=UTF8&psc=1). I will report back with how well it works compared to ordinary dish soap (Axion).
I love this forum everyone is sharing knowledge and asking questions. I am going to invite HDC to come address some of these questions about his particular design. Yall bring up relevant points that deserve consideration. I know he spent months of experimenting with the aircrete refractory mix alone. Yall are a wonderful group!
Cochise county AZ...has an alternative builders program...you can opt out of all inspections and build whatever you want.
This is remarkable. Here is the link to the building code referred to.
Annesely, it does say that this "does not exempt owner-builders from statewide codes such as the plumbing and fire codes and regulations regarding smoke detectors, nor does it exempt owner-builders from fire codes adopted by fire districts or the County."
How did you deal with these state codes?
@brian-spooner Later after I get the journey dust off me rofl I will post some links to other pioneers who like me are doing good work in this field. Maybe I will tell the story of how I came to know of this process. Air Crete and afordable sensible housing and free energy Its an honor to be involved in every way
Nice compass! This article explains that an catenary arch is the ultimate strongest dome shape for carrying it's own weight and that a parabolic arch is the ultimate strongest dome shape for carrying a load in addition to it's own weight.
Yes. That's right when only including materials for shell construction with the cement. That's not including labor, water, tools, and finishes like doors windows, lighting and cabinetry. This is why I priced $100-150. Finish is generally at least triple in cost...
Hi KatherineAirDoug, I am in the same situation that you are. Our HOA requires us to build a min 1500 sq ft home. No other restrictions other than that so I can pretty much do what I want. The wife and I are hip on the geodesic style type home and really like the simplicity of the aircrete system. I was doing some research and came across a website called Domearama.com. This site has a section, (calculators) that you can input any different parameters and it will give all the information automatically. In our case though we want the geodesic type style, and on this site it instructs you at what lenghts to cut conduit, and what angles to bend the ends before assembly to create a open shell if you will on any size or V frequency that you desire. Once the shell is completed the we are going to attach a rigid mesh on the outside of the conduit frame then heat shrink plastic on top of that. Then we will commense the standard aircrete block laying procedure that these fine folks do at the workshops, however there will be angles to cut but still same process. Once the dome is complete, and the skin is on the outside, then begin dismantling the frame inside, and lay the skin on the inside walls. Our plans is to reuse the conduit frame to build the other domes that will connect to each other. Our home needs to be 1500 sq ft so we plan to construct (3) 500 sq ft domes to satisfy the HOA's request. The property we have is similar to what you are describing, a lot of trees, so we will build around, next too, the trees how ever we want, but the trees stay. They where there before we where. I do not think that strait wall will work, but I am not an expert, or claim to have knowledge in this area, but some on this forum could prolly guide you whether or not is is feesable to do that. I hope I was some help. I want to use aircrete for the foundation, but I myself need to know how much hard concrete on top I need to apply to make it stable when one walks on it to keep it from collasping. I hope I was some help, this is the wife and I's plans on how we are going forward, it is a little different from the norm the way the domes are constructed on this site, we are always up for a challenge.
Here is DomeGaia's somewhat official statement on aircrete domes and building codes. I like that it is much more positive than my personal view.
First, check with the local building regulations. Usually you can build unpermitted structures up to a certain size. In Hawaii you can build unpermitted up to 200 sqft on residential land, and 600 sqft on ag land.
You may find that it's not a big deal to get your Aircrete structure permitted. People build unconventional permitted structures all the time. Typically a stamp from an engineer licensed in your area is required to release the county of any liability. Here in Hawaii the authorities only interfere if there is a complaint. You could go to your neighbors and show them your plans to build without a permit. If they are like most people, they'll want you to build one for them too!
Unconventional structures, such as Aircrete domes, typically require a stamp of approval from an engineer or architect licensed in your county. This releases the county from liability. You'll have to check with your local building department for specifics. Your building department may even recommend an engineer or architect to you.
I will be documenting and posting my build and experiences. I want this tech to spread. We are all relatively new to this and we are all learning. I will be soaking up all knowledge and experiences I can get.
@zander Yep I know the feeling. Kinda makes A.I. look redundant. All customer service these days seems to go this way in some variant or other. Guess the way it looks to me is two fold. The consumer generaly is left feeling pretty darned frusterated. And the CORPERATION gets off scott free. Often because by the time you get to the end you cannot be bothered. Insuch matters a human touch is needed. Something our world and its people is bereft of. and it certainly shows in the way many interact. Good on you for at least trying to get it sussed.
