      @ach2oman Any chance on sharing your "pump-less" foam generator? My replacement pump from Dome Gaia arrives today. If it does not work I will need some alternative.

      @abra said in Foaming agent woes: We assumed it was because the bubbles popped. I think it would be correct to say that when aircrete loses volume it is caused by bubbles popping and the air escaping. What is more challenging is to say why the bubbles popped. I hear stories from very experienced aircrete makers about batches that collapse for reasons completely unknown to them. They thought they did everything like normal, but for some reason the bubbles collapsed. Then they simply try again and now it works. So it seems that there is some science to making aircrete, but there is also some art - some predictability, and some adventure. @Abra please take a look at my Aircrete Troubleshooting Guide to see if there is anything in there that might help you get the kind of results you are looking for.

      @Joel Hi Joel, sorry about the delay. If you order these plans: DIY Little Dragon and Foam Injector Plans http://www.domegaia.com/store/p29/DIY_Little_Dragon_and_Foam_Injector_Plans.html They will help you upgrade your drill/mixer to be like the foam injector Hajjar builds and sells! Plus you will have a backup on how to build your own Little Dragon or repair it as needed. May be good insurance to have being in Chile! Hope that helps you! FoamAir

      California adopted the 2006 IBC without the companion housing code that would have included acceptance of AAC in seismic areas. So yes and no. AAC cost about 4 times that of AirCrete after delivery.

      While we haven't pumped vertically, we've successfully pumped horizontally by making our aircrete mixing container air-tight, then pressurizing the top with an air compressor so that the mix would flow through a hose attached at the bottom. Doing so seemed to have little effect on the foam, which set fine under the concrete slab we filled beneath.

      @HandyDan Clearly. Thus, the question is, given that the foam collapses under pressure, therefore requiring shallow pours and thereby creating layers: how does one create a sealed form that is fit for purpose? It is imagined that it would be best conceived as either a multi layer form that is added to layer by layer, or a form that can be raised and adapted to the next level. Having no form work experience, I do not have the answer.

      @AbstraktLighting Hi: You can check some of my past posts but I think I can resume some here. First thing you need to do is go to your county or state or whoever owns jurisdiction regarding code in your area. Get the local codes in pdf or writing. In some states, they are adopting the 2016 international code. There are different codes, mechanical, electrical,hydraulic, sewage, etc. You can hire an engineer to design the whole concept for you, or if you want to save money but take longer, sit down with the codes and see the minumum requirements. To give you an example, some will require concrete blocks to have x amount of compressive and y amount of tensile strenght. It will have minimums for virtually everything. As long as your design comforms to the minimum, and have an engineer stamp of approval, you should have no trouble building it and passing your county inspection. Some counties only require an inspector of the county to check each stage of building, but an engineer stamp will make it far easier to approve, since many times the county inspectors are not engineers. If for example they require a minimum 2500 psi of compressive strenght on your design, and there is no parameters for your block, you can make several of the blocks, along with the mix proportions taken to an engineering firm, and they will make a compression test. From this test you will real numbers to comply with the code. This is not too expensive and when I did it they charged me around 75 dollars for each inspection, which included taking 4 to 5 cylinders of concrete to cure and test for a period of about 3 months. Your local code will probably ask for higher tensile strengh, so you can fix this once you have your celular concrete dome built, to install iron rebar proportionate to the required streght(bar diameter and quantity), to either the inner or outter of your dome, and then spraying a layer of shotcreted magnesium oxyde cement over the rebar. This will give you the required tensile strenght, and most engineers can use a chart to give you an approximate of the tensile strenght of rebared concrete. This should put the design within the minimum requirements of your county. I still do not have a better recipe for light concrete, but a quick google search or youtube will give you many examples of people who have added the magnesium concrete or used other aggregates. Any aggregate will make celular concrete heavier, so keep this in mind. Before trying to experiment with any aggregate, you should try to first do a proper celular concrete block as explained by Domegaia. Only then would you be able to have a measured example from which to depart either heavier or lighter.

      @HandyDan said in tutorial video for little dragon construction: @upwinger Ubuntu is also a movement, not just an flavor of operating system. Opens course does work. However, in something like business it requires an aggressive effort and the highest of quality in your product or service to be prosperous. Control, exclusion, and laws have been the only way public companies can actually stay alive and be prosperous. The old paradigm does not die easy. I mean who doesn't like easy profit? Ubuntu Thanks for sharing the very good youtube video explaining Ubuntu. I knew this, but I hadn't seen these videos. It's so difficult to stay positive when you are enslaved! This forum and Domegaia are perfect examples of Contributionism... Lets make our Eutopia! My middle name isn't Eugene for nothin! I wouldn't be here right now if it wasn't for me accidentally stumbling upon Haijar's TedTalk while surfing the TedTalk library!

      @anthonydjones said in Average Cost Per Sqft: @HandyDan said in Average Cost Per Sqft: 3 gallons of Dresses foam agent Can you pleas describe or provide a link to this "Dresses foam agent"? I can't find it. There are also other almost identical foaming agents available at local farm stores. They are used for "row marking" where the tractor squirts droplets of foam so they can mark where they went.

      @HandyDan In regards to using air Crete for a floor, what reinforcing would you use and how thick would you make it. My current application would be a base for patio pavers but I’m also interested in using it for the floor elsewhere. Thanks!

      @susan no not yet I study all stuff at domegaia and volunteering to help build a dome in Sedona Arizona I will be building my dome I’m in the process self education talking to community as domegaia and build myself . There’s many on site here that gave built domes offering services I can’t wait to build dome I’m mire studying as much as I can from domegaia volunteers helping others build domes
