They should find a way to use volcanic ash and seawater type water to set it like roman concrete. How does aircrete weather in floods? An aircrete that was based on Roman concrete may be something amazing?

Aircrete (foamed concrete) was used in a lot of schools and public buildings in the UK in the 1960's. They are now discovering a lot of structural issues, leading to the closures of many public schools. It is quite a problem, requiring expensive remediation or replacement. Edit: thank you for mentioning this issue in your post and highlighting how this video's method is different.

Just wanted to share a bit of info because some people are asking about the story about how some Reinforced Autoclaved Aerated Concrete (RAAC) roofs are failing in the UK. We're definitely not experts but we looked it up and it sounds like RAAC is a different way of using aerated concrete that involves steel reinforcement. This Guardian article has more information: www.theguardian.com/uk-news/2023/sep/04/raac-crisis-who-knew-what-when-crumbling-concrete-england "With an estimated 30-year lifespan, failures among Raac roof panels in 1950s buildings were inevitable. Engineers also discovered some panels were too thin for the distance they were used to span, some lacked enough steel to anchor them to vertical structures, and leaky roofs triggered a “rapid worsening” of steel corrosion." The aircrete method featured in this video does not use any metal in the structure so it seems to be quite different than the RAAC method, but just like with any new or alternative building project, it's always a good idea to consult with experts like structural engineers, architects, etc. Thanks so much for watching :)

It's good you are addressing this here, however a deeper discussion with a materials expert and a cements expert about aircrete, would be appropriate. The statements your guy in the video are making are often vague and troubling, given that a) all materials have limitations, and b) this video can be used or misconstrued by homeowners. Finally, given the claims made in this video, information on global warming potential and structural strength would be useful.

Concrete by definition includes aggregate like sand or gravel, so the whole term "Aircrete" is a misnomer. "Cement" is the adhesive substance in concrete that binds all the aggregate in the mix together like glue. What gives concrete its strength is the combination of cement gluing together aggregate, where the aggregate itself lends its structural properties making the end result super strong. If you take out the aggregate and replace it with air it's going to be very brittle and have low strength in compression, tension, and torsion. Meaning - it's definitely going to crack. I appreciate the deep thought that can go into scrutinizing new methods of building - especially here on youtube.

My mom and I have had air-crete on our radar for nearly a decade now, and we are so excited about this foam pump!

I'd like to know about the resistance factors to extreme elements - how does it do in floods, how much mph wind can it tolerate, is it earthquake rated, are there insulation comparisons with say, straw bale, sand bag cal earth structures, or earth ships, or compared to concrete alone relative to its thickness? Can you use chicken wire inside walls vs. fiberglass, for its EMF blocking abilities? It all looks very intriguing - this was a good intro. Tho it likely varies from state to state, wondering in general how big a structure can be built w/o permit. Hope you follow up with a more indepth report. Would like to know is there an aircrete greenhouse out there?

@@PHE-nomenon Modern buildings are made of many different materials, and it's all about balancing cost, availability, material properties, and construction when choosing which ones to use in which component structures. In the case the OP is talking about, water and wind cause specific types of stresses on structures, and there are probably ways to design aircrete structures that are just as strong against these stresses (e.g. reinforcing with rebar, designing thicker walls, etc) as more traditional materials. Aircrete can't replace concrete, but aircrete-based composite structures might be a viable replacement for timber-based construction, even if there are some structural differences (e.g. maybe aircrete structures use thicker walls than timber structures)

Would depend on what reinforcement was used. And what surface layser. I'd go with a heavy mesh and rlight rebar grid sandwich, some kind of fiberglass outer layer, and hard plaster with fiber interior, and a fine plaster top coat. Interior reinforcement, and a hard waterproof shell.

What I find fascinating with Aircrete is that it seems to be the best marriage of cost, efficiency, and customizability. Most of the aircrete structures I've seen are domes but that's just becaue you can do it that way and it makes the process of building a smaller building easier. You can totally build a rectangular or square building our of aircrete, and especially with a small crane you could use much larger slabs. I'd love to try building a solid building out of aircrete and do load testing.

I would love to hear how it deals with extreme cold, or repeated freeze / thaw cycles. Conventional portland is prone to cracking and degrading. How many decades should we get out of aircrete? Can it last centuries, or is aircrete only suited for short-lived buildings? It's good to build with, it works well in the short term, but how well does it hold up?

Perfect for building a life sized fairy house. Super cool

Totally make sens to use such material. The surf board analogy made it simple to understand. Thanks for sharing. Sand will be happy !

Flinstones :D I'll take it

In my country we use a lot of Ytong. If you're building floors or columns you want to use concrete, but for walls - there is really no need to use anything else unless you really really want to. Bricks are kind of obsolete. Building with Ytong is like building with legos. And you can shape it however you want so you can make some amazing stuff. I guess you can build domes with it if you want to - just like building igloos with ice blocks.

Creative, but I wouldn't think this would pass building codes, particularly in earthquake zones. Also...instead of making bricks, I think the "killer app" for this would be to just have an inner and outer mold, and you could just make a long building with an "arcade" style roofline. You could also make this arcade into a circle, and build a central dome in the middle.
