Low Cost, Eco-Friendly Aircrete Homes | Hajjar Gibran | TEDxSedona

[@pattiehanan1356]

Absolutely fantastic! I'm a 70 year old single woman who hasn't yet owned her own home. And when I learned about green building, especially aircrete, I knew I would learn how to build this way and finally have my own home! Can't wait! I continue to research......

[@tammyslaughter9587]

My husband is a contractor and has also worked for many years in the commercial concrete business, he is about to go to one of his workshops in February. Hopefully my husband can incorporate this building material in his business. He will be building us a dome home on our land soon.

[@rondacarty571]

This is amazing and to think it has been around for years. Spread the word, keep building to open the eyes of others on how to do this. I had already planned on using this method for my "She Shed" and was viewing KZbin for updates on Aircrete and found this video. I hope the dome in Hawaii isn't in the active flow of lava that is happening.

[@dvfreelancer]

New materials like this are fantastic...if you can find a contractor to build with it and get the plans through the permitting process. After all that, you still can't get a mortgage on it. Even if you have cash it's hard to find a contractor. We discovered that the biggest challenges to building a dome home are not technical. They're logistical and regulatory. Florida should be the concrete dome capitol of the world but there are only a handful in the entire state.

[@autumnlove5231]

There are many in the Gainsville area.

[@iolanisjourney4828]

Awesome speech. Funny and great content. We certainly need these kind of houses here in Hawaii with the hurricane scares, lava, and flooding we had last year in 2018. We have seen it over and over again, the current structures we are using get demolished during a hurricane and yet they keep using the same material to rebuild. It makes no sense. Thank you for sharing and doing the work you are doing!!!

In the failed egg example, I totally know what he was attempting to do but was not able to offer a rebuttal. He meant to say that you should try an experiment with an egg, but the egg must be long side between both your hands. Then you try to crush the egg lengthwise. If you like to try it, it will not be able to be crushed because it is incredibly strong lengthwise but if you were to do it with the short side between your hands, then it would be crushed immediately.

[@OnyxAgainstTheWorld]

Montana needs this technology BADLY. Especially on the reservations.

[@SmartEasyDIYer]

Oilstories yeah imagine these dome houses with radiant floor heat! That’s one of my future projects I’m hoping.

[@calysagora3615]

Just check around, there are videos explaining how to make the equipment for making aircrete for $30 bucks. It's just portland cement and a foam made with soap, mixed together. Just use some finer metal mesh as reinforcement, and seal the surface if exposed to weather or wear. It's no secret or super complex thing, you can get going tomorrow. The extra machinery you need compared to normal cement is an air compressor and a foaming device. The saving in concrete and re-bar obviously makes the result cheaper despite the extra equipment. The foaming device is easy to make with some tubes and steel wool. Just look for videos on DIY aircrete. Go! :) I'm totally gonna try this for making my new workshop.

[@Virgilsvortex]

If you are able to get an engineer to approve the aircrete let me know I will move to Montana.

[@catlover4219]

The concern there is the covering, as all the builds are in mild climates. Montana is pretty extreme, and the temp flux is pretty drastic. Not sure outer fabric would hold. Shouldn't stop the tribes from trying it in their own jurisdiction though. Feds wouldn't care if you made it from Legos; it's state and local building codes you have to out-maneuver.

[@catlover4219]

Why not check with the BIA to see if they could hold a workshop in one of the reservations? Could serve as a mini-museum or playground amenity for example. Might inspire more.

Am definitely sold on this type of home construction but the only roadblock encountered is obtaining financing as we own a piece of property in Connecticut for which conventional financing is very stringent. Of course there is the concern of town zoning approval for which I can tell you that this type of construction far exceeds our towns building codes.

[@SmartEasyDIYer]

That’s really awesome! I’m building a pole barn house but I would love to do this sometime in the future with in floor pex tubing radiant heat for the cold north or just move somewheres warm if I can convince my wife. 😉

[@seano1334]

Smart Easy DIY would you add geothermal?

[@SmartEasyDIYer]

S O yes you could use geothermal to heat it if you had the right system. It would take up some room though probably. Maybe you could put it in a smaller separate area and run the heat inside.

[@catlover4219]

I noticed all the builds are being done in warm climates and many are NOT main living spaces, but out buildings. My guess is due to code restrictions like here in so cal, home of building Nazis and elitists. Wish some super legal mind could get legislation that would work around the absurd bldg. restrictions here. Forcing expensive solar and banning AirCrete...

The cost of land is a major factor in people having a house.

[@Paul-gz5dp]

Domes are stronger because the forces are spread out over a large area, unlike our framed homes that have many weak points because the force is not spread out.

[@sonofagun3193]

Compressive strength is low even when able to carry a car. Do you have compressive strength and specific weight figures? Shrinkage? Thermal insulation values? Are fillers e.g. sand, added to the aircrete? Hygroscopic properties? Can aircrete be used for load bearing structures? Steel reinforcement possible? Corrosion protection of reinforcing steel needed within airated concrete? Carbonisation rate of air crete? Cement additives used? How to calculate the integrety of an aircrete structure to comply with building regulations? Thanks in advance for your answer. Making cement causes lots of CO2 ...is aircrete eco friendly or green nevertheless? When the physical properties of aircrete are not known or not reproduceble by the civil engineer architect or contractors, design will be based on lots of guess work... How to be sure it complies with the Building Codes ?

[@SVisionario]

Wow what a spectacular speech, thanks. Aircrete never ceases to amaze

[@MidEastSusu]

The concept of Aircrete sounds great. However, I would like to see homes built in a more angular structure. This is because placing furniture against rounded walls can be difficult. I presently live in an adobe home in Ecuador, where most of the lower socioeconomic families live in homes of adobe construction. However, adobe is meant for dry environments (ie, New Mexico, Arizona), and, in Ecuador, half of the year is not dry. Aircrete sounds very promising.

[@heaty007]

[@nc3826]

Aircrete is fine but the cost the of material is higher and it has a higher CO2 and energy footprint. While a earth based adobe or cob construction, can last hundreds or even thousands of years when designed properly. Its roof, foundation and landscaping along with the use fibers and the use of exterior protection are key factors. Such as breathable but durable plaster mix and a lath/mesh are all factor on how durable and maintenance free or not the structure will be. Reply if you have any questions. And good luck...

[@123Goldhunter11]

This all sounds nice but you still need land to build and land in most places, like the Seattle area has been down-zoned to keep it from becoming one huge suburb. So - as population increases the available land becomes too expensive for even middle class people to afford. Add to that the importation of people from large family cultures and I don't see affordable housing anywhere on the horizon, even if you can come up with inexpensive building material. Yes - it seems absurd that people build with materials that can be burned down or blown away. I hope you can get the building departments on your side. If I ever build again I'll certainly look into AirCrete.

[@Virgilsvortex]

Gold Hunter I am also waiting on the okay to use aircrete. I believe it's how they keep us buying the same old same old stuff. The public needs to vote in fresh new ideas. Stop waiting for those in office to die.

[@catlover4219]

Agree! I'm tired of being told I can't use this, and that I must add solar and specific types of lumber. Ugh. I live in so cal, and our leaders are anything but supportive of the environment. All talk. They only push expensive new building that THEIR investments will benefit from. Politicians don't care about the common person or the environment IMO.

Hello sir, I remember in the oilfield industry, using a polymer foam in coiled tubing, in water producing wells. I wonder if these bubbles would be more sustainable with it as they had to have their bubbles last hours long in varied temperature differences. If you can find that particular polymer foam agent and test it to see if it lasts longer dollar for dollar, it might be an alternative. Thank you for all your efforts and God bless you.

[@tacticalant3841]

Jay Dixon - this might have been what my brother was describing. Is it the foam used for pumping out the drill shavings? He said they would pump it down the well and it would carry up all the small rock fragments produced by the drill head. He said the gravel sized rock would be suspended in the foam.

Well. Aircrete as he calls it is not new. Many years used in Europe. Biggest companies are Ytong and Hebel. He actually uses some of there product videos to explain his "aircrete". So no. Nothing new. Specs aren't provided by him as needed by home inspectors or engineers. Because he has none. Ytong and Hebel would have to close their factories without providing specs of their stones. Only new is that North America does not know about stones used in home building around the world. I did build my house with Liapor. Much better than "aircrete". I actually consider to go to one of his training program to see if the stones made of equal quality like Ytong or Hebel. But I think that they are not!

[@birgip.m.1236]

[@Halopa60]

So I gather that aircrete has good compressive strength but what about tensile strength? There are a lot of seismically active areas around the globe. I just don't know if fiber mesh would do the job since not many specs were given. The tropics, which are home to 40% of the worlds population, are closer to the sun so housing needs to be either shaded or cooled to keep them livable and I'm wondering how this can be achieved? I like the idea of dome homes but perhaps a reinforced concrete post and beam cage with aircrete infill walls and an aluminum roof would be more appropriate...at least for areas out of the typhoon belt. I have plans to build a house of this type but, with a double roof for shading and passive cooling however, I would rather build an aircrete dome house or series of smaller structures connected by enclosed hallways if the issues I mentioned can be overcome. Anyone out there have any ideas?

[@protonneutron9046]
