What's the largest diameter you could make without an airform (e.g. just using basalt fiber or bamboo.) Could rebar be used instead of basalt fiber as well?

[@ChrisBrown-me5bn]

So far 7.0m diameter domes have been successfully (and relatively easily) constructed without an airform. We haven't tested the limits however, theoretically, a dome of any diameter could be constructed in the same way.

[@Mgb-uo8mq]

A dome can be infinitely large and doesn't require internal support when it's completed but does as it's being constructed. The limitation would be in making the supporting structure for construction

Bamboo does not stick to concrete. it will become a Tofudome

[@eveadame1059]

🌹🌿 Great point! Any bamboo used in cement, will absorb the moisture in the concrete, causing the bamboo to expand and crack the concrete.

@me1059 Thank u for adding more substance!

[@Mgb-uo8mq]

You don't know what you are talking about. It's been done. Over and over. I hate when people speak and their experience is from their imagination.

[@Dr.ArielArik]

@@Mgb-uo8mq Yes, tofu drag constructions have been done and are being done all the time in China. It doesn't make them strong. So, get some brains before accusing people.

I would love to attend a dome workshop, but I just can't afford it. I'm the type of person, who learns best by having someone show me how to do something. Also, I'm a 60+yr old American lady with no building experience, but lots of energy. I'm not use to metric measurements either. I know Mr. Brown has an ebook and videos of dome building sessions, but I don't know if I could build my own dome from just those learning methods. Please consider bringing your dome workshops to the US Mr. Brown. I guarantee that I will be the first to sign up sir. Thanks and I wish you well Mr. Brown.

[@DreamDome]

Hi Carol, Chris Brown here. I know exactly what you mean about learning hands on so I take that into account with the video courses and I make an effort to show the details. We are working on new video courses and I would like to run a workshop in the US. It may be possible next year as we are working on a plan to get Domeshells started in the US. I can see our systems would be highly beneficial in many parts of the US.

[@carolb3327]

@@DreamDome That is such good news. I live in southern Missouri, which is tornado alley, where every type of extreme weather can occur. It would be awesome to build a small dome home that I could call my own. I very much admire what you have achieved Mr. Brown. Much more so because you are also a gentleman. Can't wait to attend your dome building workshop in the U.S. Cheers!

Hi Chris! What is the raw material for the concrete? How can I reach that rigidity and compactness, what is needed? My plan is to build fish pond with similar technology, but I have no clue about the composition of concrete.

[@Domeshells]

The concrete in this case is shotcrete which is a type of concrete that is relatively dry with additives. It is compacted by the force of the high pressure spray. Concrete swimming pool builders use a similar kind of concrete that is designed for spraying.

[@chrisk7118]

Has this dome form of building been integrated into the NCC building code in Australia? If so could you please point to it. Is there a nominal solution specified for done shapes or does it require a special performance solution? Cheers.

[@DreamDome]

Our system is not specifically integrated into the NCC. Our engineers have been designing basalt reinforced shell structures for several years and we have a 20 history of designing and building dome shaped structures including FRP sandwich panel systems, GRC/foam sandwich panel systems and high strength thin concrete shell structures.. We provide a structurally certified set of drawings for every project.

[@Domeshells]

Update - we have recently been required to produce a Performance Solution for a project in Victoria. We are in process of footings and slab now.

[@doczenith5491]

Just awesome

[@Norbingel]

What's the spacing on those rebars?

[@Domeshells]

They are basalt fibre rebars spaced at 150mm vertical and horizontal

[@Norbingel]

@@Domeshells wow thanks for the response. Unfortunately, I dont think we have basalt rebars in our country. Even then, that's a lot of rebars. What thickness? And do you just do the whole dome first then cut out the parts where the doors and windows go after?

[@peternyc]

Would these work in New York, hardiness zone 7? Do they handle cold and humidity well? I like your design over others because you are open to building larger diameter structures and linking domes together. Other KZbin dome designs seem to be limited to very small structures.

[@Domeshells]

Hi, WE are not familiar with US codes however, our domes are capable for any climate zone. The insulation layers can be designed to suite any climate zone, hot or cold. WE have built all over Australia where it gets very hot and humid and in some regions can freeze. It doesn't get as cold here as NY except in the mountains but we know we would meet code for any climate Zone in Aus. When a dome has ventilation at the apex it completely removes hot moist air and as long as the dome is not partitioned too much, taking away the feeling of the dome shape, none of our domes suffer from mold.

[@peternyc]

@@DomeshellsThank you. You have a great business. I wish I lived in Australia. I'd come and work for you!

@@JohnSmith-uy7sv we would love to help the people in those devastated areas and anyone else who would like to know they are safe and secure no matter what extreme comes along. We need to form relationships with local builders there. We can help train and educate. For anyone wanting to learn how we build thin concrete dome shell structures, Go to: www.domeacademy.education There is more video training material in production directed to professional builders.

[@TheReaderOnTheWall]

Interesting, is it with Aircrete?

[@Domeshells]

Not with air crete. We fabricate a high-strength basalt fiber-reinforced concrete shell with a layer of lightweight concrete over that for insulation.

[@warlockpaladin2261]

​@@DomeshellsBasalt-fiber?

[@DreamDome]

@@warlockpaladin2261 Yup, basalt fibre. Melt down basalt rock, extrude a fibre (2 x tensile strength of steel. Can be manufactured in all the same type of products as fibreglass

[@warlockpaladin2261]

@@DreamDome I thought it was synthetic basalt you were talking about... wasn't sure if that had been perfected for commercial scale yet or not. Even so, what's the price tag of harvesting, melting down, and extruding basalt?

[@DreamDome]

@@warlockpaladin2261 apparently, some basalt rock is better than others, but I believe most of the basalt fibre is from mining tailings where the rock has already been crushed. Requires about 1300 to 1400 degrees to become molten rock to extrude a very fine and soft fibre but with 2 x tensile strength of steel. To form reinforcing bar, rovings are pultruded through resin to form a deformed bar that looks like steel but is only quarter the weight. The manufacturing process is cleaner than glass fibre and steel. Costs more than steel to buy but is much easier to work with
