I am a new subscriber and will be learning this process the best I can from you. I am going to be building a blacksmith shop fairly soon and I love how this looks. Thank you for all the answers to all these questions. I did watch both parts. Wish I could attend a workshop, its just not in the cards currently.
Whelp, I'm sold. It looks like I'll need to go through your videos again and get an idea as to how I'll pull this off this spring. Thanks for the update and Q&A, the information is greatly appreciated! As far as your RMH goes, what's the design that you are looking at building? I've built a couple of them, my biggest was a six-inch batch box that fed into a masonry block raised bed inside my Annualized Geo Solar high tunnel. It worked so well that I was able to extend my growing season by several months up here in Zone 5A Kenai Alaska. Thanks again for the updates, and I look forward to your coming videos!
I’m thinking of building a J tube 6” system with a brick “barrel” (plate steel on top) with a stratification style cob bench. So cool that yours worked in a high tunnel.
9:19 ... plus the weight of the CO2 absorbed from the air to transform the slacked lime into calcite (slacked lime molar mass - 74, calcite molar mass is 100). Ah, yes, porland cement has some calcium hydroxide too _and_ the cement curing rely in trapping crystallization water (e.g. which water will cause the concrete to spall when heated in fire) Ummm... how about actually weighting the samples you'd be using in your bullet resistance tests (rather than relying on by-the-ear estimations)?
Right on! I've been hoping for a followup and really glad you made these two new episodes! I'm going to do it for a workshop at my off-grid place. But I'm milling my own logs and sad to hear that the fine dust from a bandmill might not be the best. No worries, shavings are cheap - I just like the idea that it came from my mill. So thanks again, will follow.
Thanks for making these videos. Lot's of great information. I saw another commenter taking a crack at the reinforcement problem and thought I'd throw in my two cents. For an alternative to steel reinforcement, there is basalt reinforcement mesh and rebar that has several advantages over steel, one of which is that it does not corrode. There is also basalt fiber which could be used directly in the dustcrete mix itself. Looking forward to the rocket mass heater. Good luck!
If the longevity issue is the reason not to use steel, you should also not use fish net made out of artificial polymers. I work in the plastics & rubber business, and we consider product in our warehouse stale after just 2 years. It's not just sunlight and ozone that degrade plastics, most also have a tiny amount of the catalyst used to create them which causes degradation over long periods of time. We add anti-oxidants to nearly all plastics but that still doesn't entirely stop that process. I'm not sure about nets made out of natural fiber materials, I don't have experience in that area so I have no idea how long they would be expected to last in this application. One thing I have learned in my career is that it is very, very difficult to know how solid materials will behave over decades of time. The only materials I know of that can be expected to last 100+ years without change are ceramics or brick.
@@danielwebb1004 Good to know! My assumption is that organic material within this system would eventually fossilize, but there is no telling what will happen after decades. I suppose if the fish net just made the panel rigid enough to un-form and move into place, that may be enough. 🤷🏼♂️
Can I just use Portland cement because where I live we can not get type s lime and will this building technique work in an area that has negative 30* Celsius?
@@sharonglazier2552 I don’t honestly know how a straight cement mix would do. People are reporting good results with subsoil clay added. A couple test blocks would be more informative than I can be, I suspect.
Really ehjoyed this Q&A video. Whats your ratio/ .aterial again for your mix? Water x Dust x ? = I've watched a lot of Aircrete videos, not a lot of dust. Aircrete is like Water x Foam mix x Porland cement. I thought i heard you say Lime in the video some where? Thanks for your knowledge and experience. ✝️🙏❤️🇺🇸
Appreciate the part 2. Was down in your neck of the woods for a bull sale. It's a beautiful area. Would fiberglass fibers incorporated into the mix help with the strength and cracking?
@radicalgastronomy I went with some rancher friends. They bought a few bulls although current prices were a shock. The bulls were Angus and gelbvieh. I'd love to raise a beef but wouldn't be a good fit on my property so I'll probably just trade my friends halibut for open range beef. Straw has been the classic reinforcing material for eons. I won't have access to straw but I'm sure I can find a natural fiber that would work
Bullet proof?! 😂 That must be the most Murican question. That said, I really appropriate this channel. Amazing material!
The most, for sure! 🤣 We will find out though, for freedom’s sake.
@@radicalgastronomy mm, yeah. Hope it doesn't come to that :/
@@octopixie Yep, that got a WTF from me in Ireland too ! Excellent videos.

Right on. Good luck with your build. If you have questions, let me know. I answer comments daily.

Cool. Thanks for adding this info!
If you don't want to use a steel mesh for reinforcement, you might consider using a fish net.
You bet

They may, or chopped straw. Did you buy or sell a bull? What breed?

Where is CZcams University?
It’s a joke. Anything you could learn at college (and more) can be learned for free on CZcams. 😉
@radicalgastronomy Well, by God.
