Este no tenia entrada porque era muy pequeno, cuando hice uno mas grande la entrada la corte luego de armar el domo ya que el cemento aereado se puede cortar facilmente con un serrucho de madera. kzbin.info/www/bejne/aXuxeJl9is5jY5Isi=vbYVDgOFT_5RRNsS, este es el video de como hice un domo de 3 metros de diametro. Espero te sirva. cualquier cosa comentame de nuevo Gracias por comentar

You are correct on your estatement but I did build the small bases to compensate the fact that a 3V dome is not flat at the bottom, the 4V dome is flat but it requires more triangles to be build so it is a win some lose some kind of situation. I am still convinced that my problem with my gap was created by my molds not being super accurate, I am working on some corner pieces to be 3D printed to have better angles but I cant seem to find the time to get that done. If you do try to build a 4V dome I would love to see your progress and experience if you want to share it. Thanks for watching

This should work anywhere, in the world, but you can also visit domegaia they have a similar build that requires less precision on the built of the molds and allows you to have a great aircrete dome too :) Thanks for watching

Thanks for your comment, but I dont see how a square building is more efficient?? Granted my first attempt wasnt the most efficient as such, the potential for this type of building to be 10 times faster than your traditional square building is there. I fail to see your point. Care to elaborate on where you see the differences??

@@juanconhambre Build time... Square building is less efficient. Your time more efficient with square building. a tenth of all that hard work. Extra time working off site = $ for 3-4 more solar panel to heat and cool. your still better off. But you have something of beauty. Time has so much value as you get old.

There are several calculators online, I really like zipties.com website, easy to use and pretty much all the info you could think you need is there. Thanks for watching and know that I havent stopped working on this I dont have much to report at the moment but I am hoping I will have more videos coming next year

E mais dificil de fazer a casa domo con bloco ceramico o de concreto porque them que fazer cada bloco ter u angulo corecto. Disculpe meu portugues e maluco. Este video foi meu primer intento para fazer a casa domo asi, espero para o proximo intento trocar algumas coisas para fazer u proceso mais facil.

me puedes contactar por correo electronico, [email protected]

It is holding still, it did crack on the first winter, mostly because I didnt have the burlap and my base is not the best. I am in the process of working out a better system before I build a bigger one with. I will keep you posted. thanks for watching.

What do you mean with mix in some mud? thanks for watching

@@juanconhambre take some subsoil get it wet nice and muddy mix in some cwment so it sets up hard

@@prototype9000 that would work for what I want to do as it isnt insulating, the bettter benefit of the aircrete is its insulating properties for the north. Thanks for the comment, different points of view are always welcomed.

if I understand your questions the coefficiency of expansion will be determined by the size of the dome, there are many calculators online to figure out the lenght of the struts that are the lenght of the sides of each triangle. Hope this helps. Thanks for watching.

@@juanconhambre Thanks for sharing

No additives, just portland cement and water with foam. I played with some additives but didnt really improved the aircrete. Hope this helps. Thanks for watching

thanks for watching

maybe you should try opening your eyes, the video has poor lighting but if you cant see that you might need glasses. Also ultimately if you cant see it you dont have to like it at all, as matter of fact you didnt have to watch the whole video or waste your time commenting, that would have been probably the better option for everybody involved. Have a great day and get those eyes checked out I am worried about your eye sight

What do you think I did wrong on my curing? I am always happy to learn if you have anything that I could better for my next attempt I am all ears, also dont forget that I am not working with regular concrete but aircrete, it does behive similarly but not quiet and to top it all out I live in a very dry environment. Thanks for watching

I have started the process of making corner pieces for my molds for accuracy, but my CAD design capabilities are limited, it will be a work in progress for a while but it is I believe the best option. Thanks for watching

I never weighted them specifically but they weight around 20 to 30 kilos or 40 to 60 pounds I would guess I was able to move them around by myself. it is more about the awkward size, obviously as you make a bigger dome the size will increase therefore the size will increase but my guess is to make a 25 foot dome 2 people should be able to still handle each block. thanks for watching

Hi, have you tried the aircrete?? you can reach out to me at [email protected] if you want to ask questions I dont know much but if I can help you or point you on the right direction I would love to.

Dont worry it istn meant to be lived in or even used to be honest, it was a proof of concept, but after 3 years it is still standing LOL. thanks for watching

@@juanconhambre as long as no one is at risk, no problem. I've had numerous wire ties fail in exterior use, I think uv must deteriorate them.

After I built it I bought some Helix rebar but I have not experimented with it, I am not sure if it will help because the micro rebar might break to many bubbles making the aircrete less insulating and heavier. I have seen some people using basalt fibers to make aircrete stronger. I personally think my cracked bricks are due to my poor aircrete skills, I did notice towards the end of my brick making I was getting stronger and more consistent bricks, the key was to not rush the unmoulding to make sure it had time to cure with enough mositure, I could have also unmoulded them and water them but because I was working inside on a shop I didnt want to deal with the mess so longer curing time was the answer for me. When I do some helix rebar experimetnation I will post a video about it Thanks for watching

Hope this helps, I would love to see yours when you are done :). Thanks for watching

The flimsy pallets like I have explain in many comments before, is because the price of wood is really expensive where I live and I could not afford to build the whole project if I built traditional wood structure. Also the flimsy pallets you talk about are all hard wood pallets, way better than pine if you ask me. I build a solid foundation of 2" x 12" under the pallets, the pallets are there for me to walk not so much to support the weight of the dome, that is done by the joists underneath. The foundation has lasted 3 full winter with a full snow load and is not even tilted 1 inch despite the many thawing and freezing cycles. Next time if you dont have anything positive to contribute you should save everybody some time and keep it to yourself. I dont mind the questions on why I used pallets I do mind the way you ask it. Thanks for watching and remember that there are people that at least try to add to the world more than just negativity :)

I have not tested anything on the R value of the aircrete, I would say the best channels I found where Honey Do Carpenter and Aircrete Harry, not very scientific but they did run some tests on aircrete. I didnt do much since my dome wasnt airtight enough to see the Aircrete was good insulation. I just found another guy that has been doing some aircrete videos, his name is "the happy heresiarch" I watch a couple of his video and he seems worth checking out if you are starting. If you have any specific questions on aircrete shoot them my way I will help you as much as I can for sure, you can reach me at [email protected]

Hi James, I dont know if there is an oficial open source project, I have made my information available but I am run out of money and time to further pursue more on this, I am trying to save some more money to continue but it is a tricky to do it all by myself. That is why I posted all my findings in the hopes someone else can also take on this project and improve uppon it. So far I have had a few really good ideas come out of comments, I am hoping to put some of those into play next time I have time and money to build another dome :) thanks for watching

@@juanconhambre I love your idea presented in this video. how can I help? what is the next thing that you are wanting to experiment with? Maybe I can help, or maybe the next person can. Do you have a website?

@@jameshouse2909 I dont have a website or even a forum, my next step is to work out a better way to make the molds so they produce more stable geometry. The best idea from my point of view is some sort of locking mechanism to make sure the triangles align, I was leaning towards dowels but recently somebody recommended a tongue and groove system, from that I though maybe a 2" x 4" going across in sides of the triangles with some on top and some on the bottom, the tricky part is to come up with an array that works. At this point I cant remember if I stated in the video by my end goal is to make a dome with aircrete where anybody can do it with very basic tools and knowledge on building. there will be a trial and error for the aircrete but the tools have to be your every day tools you can get anywhere. So no fancy and costly machines are to be used. What is your expertise or background, what do you think you can contribute on this project? I believe in the wisdom of crowds so I honestly believe that everybdy has something to add to this project. Thanks for offering to help Juan

@@juanconhambre a groove system does sound a good idea if it works. Have you thought about CNC moulds? I have CAD skill in solidworks and the new kid on the block Onshape (check this out for a free online cad software. it’s great) I do a bit of 3D printing in my spare time also, so no stranger to creating models. I also know the basics of getting projects onto GitHub. Traditional used only for code but people are putting all sorts of project files on there now days for people to collaborate and fork if they want, and it’s free. I also have the passion to make a system that anybody, no matter what their skill level, could buy a couple of moulds, some concrete and an aircrete machine and be able to build one of these domes. Because that is what I want! That is why I was so pleased to see someone doing it. But I don’t have a good understanding of the geometry of these domes. That I still struggle with. Do you have any suggestions where I can read up? Have you seen what the geoship team is doing? They are doing some amazing work. You should check them out if you are not already aware of them. James

@@jameshouse2909 Good morning, thanks for sharing that with me. I also have dabbled with CAD software, I did build my first dome on sketch up but it was a bit hard to learn and it then become burdensome due to my lack of skills with it so I stopped using it. I have a friend that is going to show me how to use FREE CAD to learn that software I am pretty sure once I understand better a CAD software I can migrate that knowledge to another one if needed. I have done a lot of 3D printing and I got a friend to design a corner for the molds, they take about 70 hours each to print as I have to use really high infill to make them durable but ideally they could be re designed to be more printer friendly, this was my first attempt and I didnt have as much 3D printing experience then. I dont really understand GitHub but I have heard about it for a while so it would be nice if you can summ it up to explain you did mention that is used for code and sharing files but I dont really understand it. If you want reach out to me at [email protected] and I can send you a really good book I found about domes, it was written in the 70's on the dome home golden era but the math and geometry is all there and is the best source I have found for domes and how to build them with many shapes and materials. We can be in touch over email if you are interested in helping me expand on this idea.... Thanks

And how do you propose I check that? Geodesic domes dont have straight lines to make level, if you look at the structure the lines of the triangles dont lay parallel to the ground. That is why the angels are so important, they should give the curvature and the "level". Thanks for watching.

I have thought about that but I havent been able to come up with an idea that incorporates the tongue and groove into the molds where they are not fragile and break when dismounting. Any thoughts on that? My closest approach was to do a top and bottom registry like a french cleat system, but I couldnt really make it work for the corners. Thanks for watching.

What about index notches on the edges of the blocks or key notches and protrusions something like a sawtooth edge but with larger squared off teeth. You would only need 1 or 2 teeth per side. You could also lap mound the edges of the blocks so they interlock instead of just relying on the weight and taper to hold them in place.

That was lap joint, the autocorrect keeps making mistakes for me.

@@cliveapps7105 That might work I would just have to play with the location of the teeth so they line up through the dome, I imagine it shouldnt be to hard to come up with a configuration that works. I like the sawtooth idea, 1 or 2 should work and I can make them with 2" x 6" screw to the sides of the mold, that should be easy enough to dismount from the mold and would be shallow enough to not be to fragile.

The other thing I thought of is to buy a cheap dome frame with plastic or tarp wrap kit and use it for the mould frame. Coat it in some sort of release agent like animal fat or wax and pour the air create on top in layers slowly building up to the desired thickness. When you are done remove the dome frame kit and use it to make another dome. Should be able to use the frame quite a number of times until it is too rough to reuse. Cheap 20ft frames are around $3k, if you can use it 30 times before it gets to trashed to reuse that is only 100$ per dome and would save a lot of time. If you are careful with the frame you could probably get 100 uses out of it before you needed to replace it. That would be 30$ per dome and would save about 3/4 of the building time.

the dome wouldnt need supports if my aircrete was good enough, when I did my 10ft dome I only needed them to let the mortar set. Igloos work because they are much shorter and they use really thick blocks of snow. it is a very cool design but to make a 20 ft igloo you will need a very thick snow block and you probably will still have to brace the last bit, the rely on the short span of the igloo to help them plus the way igloos are built is by cutting the block on site with snow knifes that create the curvature on site. My little dome ended up collapsing when I tried to move the pallet by pulling it with my car LOL. my other dome is still standing after 3 winters with full snow loads on top. Thanks for watching

Thank you for watching

no end use for that, it was just me testing my idea before I size it up, you have seen the bigger model with bigger issues ha ha ha. The end goal is to make one big enough to be able to live in it and use the aircrete insulating properties to help with the arctic climate. thanks for watching

But the faces are scratched anyway so maybe that makes no sense.

@@AndrewHelgeCox I dont know what GFRC stands for I imagine a type of release agent, I dont think the chipping happen due to the bricks sticking to the mold, most of the breakage happen due to my inexperience and rushing the dismoulding. Another issue was the moulds not being perfectly built which then compounded the errors at the top. If GFRC stands for something else, please clarify so I can learn more about it of course. thanks for watching

juanconhambre GFRC is Glass Fibre Reinforced Concrete, a technology which allows thin form like interior furniture to be created out of concrete. There are lots of videos on using it to make kitchen countertops on here but that is just the start. I guess I was thinking of a solid concrete face then a layer of GFRC and then aircrete to fill the centres of the forms. But that is just an idea. Maybe one day I will try it. Thanks for answering me and I look forward to,your future videos.

They dont build geodesic domes :), they use snow knifes to carve the blocks to fit the previous one, it is really cool and easy if you know what you are doing. I think they had it right on the shape as dome shape homes are more eficient to be built and to heat up. thanks for watching

What else would you like me to share, I explain my thought process and my plans. If I can help you with anything else let me know. Thanks for watching

@@juanconhambre thanks I am preparing for building a 25ft dome house in my hometown in India And gathering whatever data I can collect from KZbin and Google

@@juanconhambre sure, I will be making a video as soon as I get permission by the authorities to construct Dome House

What can I say, I had to save money somewhere and I thought the nice shipping pallet touch was a good one to add to my project. thanks for watching

I built some custom triangular molds to make the bricks, the compounded angles I calculated by building the bricks on sketch up and measuring from there the angles needed. I did not get my molds accurate enough so i am looking at alternative ideas as I think it will be hard to achieve the angles using a simple mitre saw, to much deflection of the blade that then compounds through all the bricks and makes it really hard for the last triangles.

@@juanconhambre OK thanks for the info. It's hard 😊

@@alarikgreenland you are welcome, hopefully it helps

I made a mold for the triangles, as I was trying to simplify the process. I know there are other ways to make domes this was my trying a new approach. Normal bricks would not have enough insulating properties plus I cant find them where I live, or it would be ridiculously expensive to buy, if you want to know where I live type, Inuvik NT, Canada. It might give you a better idea why I need all the insulation that i can get. Thanks for watching.

@@juanconhambre I completely get it now! Also the round dome makes a lot of sense, while its the shape you can keep the most warm. Ive heared people build buildings using a normal concrete frame and then using aircrete to make the walls. If you are looking for some good concrete books: archive.org/details/@artifact95, its my archive.org page. Greetings, Jeff

@@jeffjefferson2676 I will have a look at it, thanks for that link and if you have any ideas on how to improve this let me know I am always open to new ideas to improve this new idea :)

​@@juanconhambre Well you could just build a mold out of triangles, and use that for a pour. You can use plastic spacers to keep a wiremesh in the middle of your mold. When the mesh is placed, you can use some bigger triangles for the outside mold. You can use pvc pipe and long bolts to keep the outside mold in place. You can pour in stages, and use the outside molds again. You could also do that with the inside triangles, but then you have to build another structure to support the inside mold again. It can be done though, but it might be more of a pain then a pleasure, however when materials are that scarce, it might be worth the while. When you want to use a foundation, you will have to be 12 inches or 1 feet below the frostline to be precise. And while you are in an area with a frost line real deep. You want to look at this www.climatechangenunavut.ca/sites/default/files/permafrost_nunavut_eng_reduced_size_0.pdf I dont know what the soil look like under your house, but what you could do is dig two stories down until you hit bedrock or are below the frost line (if that is even possible) and build yourself a really big two story cellar. :) Now that might be a bit much for an aircrete building. One more thing, use a pondliner, or some other waterproof barrier to pour your slab in. Maybe its best to first make a frame for the building, put in the waterproof barrier, pour an aircrete layer, and then pour a hard layer of concrete so you wont puncture the aircrete. Planks would also do well, or something to spread the weight. Water proof barrier/liner... Any way! Good luck! Greetings, Jeff

@@jeffjefferson2676 Bed rock here is intermittent so digging isnt really a common thing plus you would have your cellar having to fight the ice and cold all year round. We build on stillts or pads and that seems to work, not differente than any other house for the dome, as long as the base is sturdy enough, maybe pallets isnt the strongest material but I didnt want to spend a fortune on wood to test my idea. I think your idea of a double layer dome is great but like you said it would be a lot of work, I think it would add lots of insulation value if the two layers arent touching and it would also make it very sound proof. I think I will stick to my one layer approach for not but it is something to consider for larger domes as the trianlges will get bigger and heavier, so by making 2 thiner walls you can save on material and weight. Thanks for all the information you are sharing it is really interesting and very useful Juan

Hi Eddie, the aircrete is pretty runny so I think it would leak out if I using a pipping bag to fill the voids, I wanted something light and flexible to fill the gaps that is why I used foam. if my gaps werent so big or in the inside I would do as you suggested. Thanks for watching and sharing your thoughts.

@@juanconhambre I didn't realize it was so runny. Was that your first build?

@@eddielane9569 kind of, I did a 4 foot dome, before this one, it is somewhere on youtube too. but my aircrete was not as good and it did not last long. I have to explore further into it but the cost of concrete is high for me, due to the weight to get it up here where I live and I also dont have a lot of time to devote to it right now, I plan to keep exploring this idea just not sure when... but in the 2 years since i post it I have received a lot of comments and idea which have been really helpfull...

Hi James, I have the same idea just testing the aircrete idea to combine the polystyrene and concrete in one step basically. How did you join the triangles with treaded rods? did you put nuts in them or how. I would love to see some pictures of your dome is you have them. Reach out to me at [email protected]. Thanks for watching

Not a bad idea in the sense that is simpler, but I wonder how big of a piramid I would have to be to be usable space inside. This dome that I build was a proof of concept but it is easy to scale up to a liveable space size. I guess I could build a piramid on Scketch up and test your idea, I think at certain size the piramid would require some serious lifting power to bring the four pieces up. But I do like the idea for maybe smaller building like a tool shed or even a green house.Thanks for watching
