Very generous of you to share the results of your experiments and final conclusions! I certainly appreciate the value of all the hard work you've done! Thank you so much. Looking forward

@20minutes it’s amazing you didnt get hurt!!! So happy to see youre well and sharing all this awesome info. Thank you!

Bless you Stephen (and your wife), for stepping forward and adopting. It takes special people to adopt.

Fantastic job! I'm sure I speak for many others when I say thank you for such a detailed and informative video. Good luck and best wishes to you and your family in your new home!

I'm very inspired and excited about your research and results. Please continue with this work.

Stephen you are a superstar in your presentations, you are a great instructor and instill confidence in those who may be pursuing this revolutionary idea. Thanks Stephen

Amazing! Thank you for sharing the results of your hard work and research.

One of the best videos on KZfaq! I think this is one of the best alternative building techniques I have seen on KZfaq

It is a pleasure to greet you. I am Gustavo Moreno López from Colombia. I am really grateful for your ideas and the way of transmitting them very clearly and completely. It is a pleasure to meet enterprises like this

This was fascinating, I didn't want the video to end.

Happy new year! Appreciate you sharing your knowledge.

I love your content, friend. Thanks for innovating. Have done cob houses. Thinking seriously about aircrete; your insulative aspect is a welcome development.

Grateful for all the knowledge & information shared !

thanks for all the good info. you answered several of my questions.. by the way happy new year.

Stephen, great channel, I love your simple approach to everything. Here are a couple of possible solutions to some of your challenges: 1. Foam solution issues: Add foam solution to the air using an eductor (aka ejector), so you can use an atmospheric plastic barrel as the reservoir. This is what is done to create fire fighting foam. Simplest eductor is a tee fitting with the air blowing through it, and the solution sucked through the "tee" leg. That is also inefficient, but more efficient eductors can be purchased that would have greater suction with less air use. Tee should work, so long as you don't have much pressure in your foam generator (hose with scrubbies in it- that is genius btw). Next step would be to use a "well tank" or "pressure tank" for the foam solution. They have a bladder in them that would prevent the corrosion issues, and the internal pressure would store the solution in advance even if your pump died to prevent loss of a batch. 2. Overflowing of the styrofoam bag bucket- Use a vortex to separate out the beads from the air- this is what is done in dust collecting systems. if you have room, use one barrel to capture the beads, and another to filter the air. I would shove the hose into your octagon device and screw it to the side so that it shapes the incoming air into a vortex- foam laden air goes around the outside, clean incoming air goes up through the middle, exiting through a new pipe coming out of the center of the octagon. The new pipe goes into the top of another barrel filter, this one with larger openings, so you can see when the styrofoam is overflowing from the first barrel. I would suggest to make it square with a round opening on the bottom to make it easier to build. Second barrel can be overflowed into several times before it needs emptied, or just swap the barrels. If you don't have room for two barrels, shove the hose further into the octagon so it dangles down into the barrel, and build a new larger screen filter house on top of the existing one. The dangling hose should stir up enough beads to allow you to see it is full and stop, and still fit the beads into the bag. 3. Lawnmower barrel & size of incoming pieces- I would recommend putting a flat plate on the bottom of the lawnmower, with a smaller rectangular chute for the incoming styrofoam. The chute needs to be big enough to allow required airflow. The shape of it should prevent clogging and larger pieces from just swirling around instead of getting chopped up. The suction from the mower should pull the pieces into the blades making things simpler and allowing for longer rectangular incoming shapes.

Awesome content. You are very thorough and your content is well presented. THANK YOU for sharing failures (Wall form blow out etc.) That is how we learn.

God bless you man, you're doing great work!

I luv how u think. Create the solution. Dont accept the problem. Very innovative

I love your mechanical inventions, very creative problem solving.

Your video really helps. I have seen several other videos where people are failing trying to use aircrete. I have seen styrofoam used with more success but did not have a good source where to send people forva good example. I will be sending people to this video from now on

Thanks Steven!!! Grate content and motivation.

Stephen, great video! and just a quick share.. We just acquired the same mortar mixer. Unfortunately, prices are climbing. Multiquip had 4 price increases over a year. We paid roughly 3600 for the EM90ES, which included the optional tow hitch. Folks, get your mixer sooner than later! Honda engine parts are scarce thanks to the pandemic, and the electric models are moving pretty quick, likely just because there are so few parts for the gas models!

I have looked at many different alternative ways to build, aircrete, dustcrete, using regular cement blocks, working with stones and concrete, but styrocrete looks like a great alternative.

very sharing and informative ...rare in people today cheers mate

Nice job. Like the fearless innovation.

Thanks for your informative videos. I will be starting my first aircrete project in spring. I will be using the polyester beads from some recycled beanbag chairs for my mix but if I need any extra I will use a cheese grater on some solid blocks of styrofoam. I will also be experimenting with a concrete canvas made with a mix of concrete and elastomeric paint.

You are a thinker and a. Get it done man. Thanks for interesting video gift. God's continued blessings

I just love your channel i just wait one day i could build something with this material. I really want to learn how to make it a viable solution for my construction project.

Thanks for your videos😎

DUDE YOU ARE THE MAN.... THANKS

Thank you Stephen!

Thanks for sharing again. Side note those are some stout saw horses! 😁

I did the workshop with Domegaia for building domes with aircrete, and their foam generator is great. The trick according with their recipe is that you have to weigh the foam until it has the right weight and once you do you set at that number and the foam generator will produce a consistent thickness of the foam. But I do have to say the bricks we were making from the mixes didn't always come out great and oftentimes was dependent on the weather where we were. On a couple of wet cold days it was not great. This technique looks promising and would need to make bricks to build the domes from.this mix instead of regular aircrete. They also used a reinforcing fiber sheet you are using.

love your content!

Suuuper! Thanks!

Enjoyed your story. I was starting to wonder if you were going to keep posting videos! Glad you didn't fall when the wall form popped open! Yikes!

Thank you for the detailed overview. Looking forward to experimenting with this stuff. There are relatively cheap compressor driven stucco guns that might make the skim coat and the stucco coat go on quicker. One question - as I have done a lot of work with mixing my own concrete from base materials, I have learned that the order you add things in is very important to 1) how quickly the mix stirs up and 2) how well mixed the final product is. The order of when the cement and water go in in relation to aggregates is especially critical. My experience of adding water directly after adding the cement is that the cement will form lumps that are difficult to get mixed out. Was this really the best order of adding materials that you found?

Man, I have bin seeing you for a long time, perfect Foam styro creete Perfect Start doing it IN THE AZORES

I am glad to see the problems I had with aircrete confirmed. Have you tried making a batch of styrocrete without using foam?

LOVE YOU!!!!

IM IN DOTHAN ALABAMA . LONGING TO HAVE MY OWN HOME SOMEDAY . MONEY IS THE OBSTACLE THANK YOU SO MUCH FOR THIS! IM DARING TO DREAM!

Hi. Thank you for all the videos you posted. Great source of knowledge. My question is: Why bother with aircrate? Why not just add styro instead of aggregate to your standard concrete mix? My brother is currently building a house out of shipping containers. We needed to fill some space before final coating. Nothing structural. We mixed water, portland cement and shredded styro. We also added some glass fiber leftovers. The final mixture is "wetter" than what you are getting so it's definitely better for molding. We didn't do any more research, because what we produced was good enough for our purposes. Take care. Great content.

I am very enthusiastic about developing this idea in a tourist area of ​​my country, cabins with direct access to the beach, I also want to teach many low-income families to do their

There is so much information in this video. Ive been a carpenter and mason for forty years and this is inspiring. I can't get past-Why the foam? In cordwood construction (Rob Roy wrote several books) they use sawdust in the mortar to get to coefficient of expansion and contraction similar to the soft wood log lengths. I wonder if wood shavings or sawdust or even polysorb could be substituted for the foam? I feel like the foam is the technological sticking point that makes this beyond the reach of a lot of people. Most of those bubbles must pop any way. Shredded leaves or straw? There must be a low tech substitute for the foam. I love Portland cement. It is so versatile.

awesome thank you sir

A few words of advice that may help others: 1. When you build an extension cord for 220V, you don't have to use such thick wire diameter as with 110V, as literally you are running at half the amperage for the same power. In Europe we use 3.5mm wire (12 awg) for pretty almost all use-cases, it should hold at least 4kW continuously without problems. 2. The concrete mixer you got is extremely fancy. In europe we have these round drums (if you watched videos with guys from Ukraine you saw them 100%) mixers. They will set you 150$ and do exactly the same function yours does, with the addition that they are so simple that literally nothing can break in them.

Sweet. Thanks.

I poured our house with standard steel foundation but placed the first row of 8x8x16 in the wet concrete along side a 2x8 jig

Roofing companies also dispose of sheets of styrofoam when they replace flat rubber roofs.

love this guy

Gr8 video mate. Very interesting. Don't know be aloud in Australia cheers

Hi Stephen, Thank you for all the great content! Do you plan on trying to build with just regular concrete (no foam) and styrofoam mix? The foam maker seems really difficult to build and troubleshoot.

nice editing very good

I am loving what I'm seeing. Thanks for sharing. do you see giving workshops in your future. If so, I would certainly be on board.

@Stephen Williams I may have had an epiphany on changing out your pressurized tank for something easier. Get a Graco or even a harbor freight airless sprayer and you can probably create a nozzle for the end, or just stick it into a bucket and it will foam. You could also do an hvlp gun with a modified feeder possibly. Anyways, thought I should throw that out there.

Always great to watch, I would like to see how you made your air only generator. Less moving parts the better! Does it provide quality foam? Is the only draw back rusting? I noticed Drexel is super corrosive.

I've been looking at something similar to insulate shipping containers for use in the Canadian Arctic. Specifically with R-40 walls, which requires walls that are thicker than 3.5" or even 6". Instead, I was thinking of using aircrete blocks and using them as giant bricks and arranging them outside the shipping container like an aircrete shell. Styrofoam could be a a great filler for the blocks to hold their shape. I do have a Little Dragon from Domegaia, but I'm also wondering if rather than using air if you had used carbon dioxide as the filler instead within a sealed giant block mould.

thanks for sharing friend...Creator bless...doug

This is awesome!!! Thank you so much for doing this, for sharing this. You've given me some ideas I might otherwise never come up with. A few questions for you. Now that this building is about a year old how has it weathered and handled day to day wear and tear? I guess that would be my main concern or inquiry, considering the styrofoam factor. And one more question, would using perlite have about the same outcome as the styrofoam? I know they use it in concrete products sometimes.

I feel like this would be amazing with a 8x8 wood beam construction and rebar staggered down the center Doing a 6" styrocrete pour you could use 4x8 sheets of Typar housewraped plywood, doing large panels. Then. Fill pour spot or pour through the 8 in beam using a 2 in bore hole. Just a thought . As thatd give more structural integrity also and give the building a really sweet look ..

thanks for your video. I've seen a lot of the other utuber channels you mentioned,,,Aircrete Harry and Honey do carpenter using aircrete. I did a small experiment but need to make a better styrofoam shreder. Another channel who is using styrofoam in concrete for added insulation is J Mantzel down in Panama who has done a tremendous amount of construction work. Good luck in your building endeavors,,,Dave.

Praise God that I found you...u are a genius....!!! I wonder if the material is water proof and if can be surround with lots of soil (like sinking a house)

As a serious 3D printer hobbyist, I can tell you that we get strength in our 3D prints the same way: more layers of SKIN on the OUTER WALLS, rather than the % of "infill" (how approaching 100% solid is the interior). My only concern would be using this in any earthquake zone where I think you would definitely want structural support in the wall to support the load, and the wall just doing its thing.

just a thought you could always acid the tank to clean it out well and then use a gastank sealer I think all are ok for water use..

Very neat. If you get a way to pump it in let me know. I have an 1886 Victorian that had holes bored in the siding with urea formaldehyde foam put in back in the 1979s. While it’s good, it’s very unstable collapses with any disturbance. I’d love to pull the plugs and pump this stuff in.

Great info thanks for taking the time and effort to share. Your sharing can change the world for the better by making housing affordable to everyone. I live in Florida and would like to build a similar structure. How did you get your permit? What challenges did you have going through the permitting process?

This is great. Were you able to get this past your building officials? Did they require an engineers stamp?

wow you solved so many challenges and did this on your own!!?

I would try por 15 fuel tank sealer in your air tank. Or an epoxy coating for gas tanks. If the interior of the tank is coated no more black iron rust. Just a thought.

Hi Stephen....LOVE your videos and thank you for sharing, Question...whats the bonding agent/glue you use to attach the mesh to the walls without melting the Styrofoam?

tuba 6 or tuba 4's...love that southern drawl baaaaaaby

Love your idea, thank you so much sharing your experiments. Do you have problems with getting the permit to build your workshop?

I'm acutely interested to see how the building/s you put up in this manner hold up. I watched your video about using fiber lath reinforcement on a styro-aircrete garage and found it quite interesting. I've seen a lot of videos and done as much reading as I can on aircrete and the main takeaway I have is that if you're a mason building with aircrete blocks there's clear guidelines on how to do it, but otherwise it's kind of a wild west. I've also never seen anything that would suggest mixing styrofoam in does anything for the strength. If it can be safely incorporated into buildings it would be pretty fantastic but I keep coming back to that strength concern.

Thank you for your work on alternative building materials. Is there any research into off gassing of the foam or what happens in the case of fire? I'd think it would give off toxic fumes/ smoke and become dangerously brittle. Any research /results would be appreciated.

Great video man! I'm curious, can you spray styrocrete onto a rebar/mesh shell? I'm wanting to build a dome home. Thanks!

Might be able to use a reciprocating saw to vibrate the concrete in the forms. Could you drill a hole in the bottom of that trough and have a valve with a hose and just pour in the mix? Maybe a 3 or 4 inch hose that went to 2 inch pipe.. That would depend on how wide wall was. I wonder if you could just use fiber mesh? No plywood form.

Thanks for sharing. At 26:16 of the video, are you building another wall to the existing wall? For more insulation?

Nice

It's an intriguing idea, but seems to have some real world issues. It's alarming that you had to brace that one wall. I'd like to see some laboratory and mockup testing on the real world performance of the entire wall assembly under various loads and climatic conditions. I wouldn't want to invest all that only to find out that the hard shell delaminates after a few freeze/thaw cycles, or that it becomes a breeding ground for mold at a certain humidity level. Still, it looks like you're on to something good. I wonder what would happen if you added fiberglass fibers into the mix or added steel mesh in each panel? That does wonders for concrete generally. Great work! Thank you!

Did you consider pouring wall sections flat on the ground then lifting them into place with mortar to join the sections? Seems like it would eliminate the need to pump or pour in a vertical orientation and the packing would be easier on the ground.

A fiber mix supplement may prevent bowing and prevent the shell delam

i did this same thing 17 years ago.. i found that using Styrofoam that was broke down by sanding .that the mix will be stronger because the gloss on the balls of Styrofoam is broken and sticks together far better ..

Hey Stephen, Have you seen SABSCRETE? Build with foam blocks, then trowel on fibrous concrete. No forms needed.

suggestion - add some lime to your stucco mix. old roman thing but makes the cement coat continue to harden over time.

I'm very inspired by your video and research of the engineering. But what about the shredded Styrofoam /styrene exposure and off-gassing hazards from within the wall? Can it still off-gass through the interior?

Will you ever make a video explaining what you use for your foam?

Can you post your how to make your aircrete foam. I'm not sure on the proper ratio. And what is the ratio for your Styro-Aircrete please. I have watch so many videos and your videos are very detailed and inspirational.

Just the info i was searching for. Are you adding anything to help bind it better like galvanized shredds or fiberglass

Hello Stephen found your videos recently very interesting just curious as to how your garage building is going. By the way are you in Florida? I am considering Garage workshop and very intrigued by your building thank you for the teachings and blessings

I am curious how much pressure are you putting on the air tank? If it is relatively low you could just use the same setup you have now on the top thru bungholes of a 50gal plastic drum plumbed with discharges at the bottom. More volume and no rust.

I have an old barn with sandstone walls that I want to close in to make a butcher shop. Need to seal the inside face of the stone to make them rodent proof. Your thoughts on using something like this against the sandstone? No water coming in but wasn't sure if natural moisture from the stone would be a problem? Was thinking I would use the PVC wall panels on top of this to give it a clean look and waterproof seal on the inside. Possible to glue the panels to the styrocrete or need to leave the osb in place? Finally, is it possible to make it in smaller batches with 60 pound bags of quickcrete say with a tumbler mixer or do I need the big kahuna? Thanks, great video. I subscribed for more.

Thanks, Stephen for the tremendous video. It would be good information for planning if you would tell us how many cubic feet your recipe approximately makes using 3.5 gallons of Portland cement. Thanks for your answer!

I like the concept, but what about building codes? Local government engineers buy off (permit)on building with this stuff?

You can make a device fairly cheap for checking the compressive strength of your mix. All you need is a hydraulic jack, a hydraulic gauge, and a little bit of math.

Did you think you were going to fall with that break on form? I think that would be my first thought. Thanx for vid

Stephen, I sincerely appreciate all your efforts and expainations and will be applying the knowledge for my next house. Please keep up the great work and ignore the narrow minded morons with negative and/or irrelevant comments. I'm afraid that's the mark of laziness and ignorance that has been overruning our great country...

Would adding fiberglass fiber in the mix help just like it does in concrete? I ask that for the fact that when I haul ready mix a lot of commercial builders preferred that over using rebar

Curious as to why you would add the foam. I'd think the Styrofoam essentially does the same thing and you'd have a stronger mix.
