I have an idea, I am to old to start a new venture, but someone out there may want to pursue this idea. I would like to build aircrete logs. Based on the toys we all played with when we were kids, Lincoln logs. These could be pre-manufactured so really almost anyone could buy the logs and construct a building. There would need to be different lengths made say like 2, 4, 6, 8, 10, 12 feet etc. There would need to be some that had special ends with channels for doors and windows. There could be some that are pre wired with wall outlet boxes and switches. Logs could be pre-colored or surfaced in some cases. A building could be constructed permanently by bonding the logs together, or could be temporary and disassembled and moved. I think this could be an amazing new business that could revolutionize small buildings. And it would allow for any person to DIY.

I like this guy. He is a good man. He take everything he encounters and improves it.

Thanks for this well thought out and presented video. The down to earth tips are valuable

This video is really a good tutorial on making good quality aircrete. Can't wait to try this.

Very awesome video! Thanks so much for putting this together

Thank you so much for this and all your videos. I have learned a lot. They clarify so many questions!

Can't wait to see more videos about your aircrete projects. Would be nice to see some follow up on the panels you poured- their final weight, strength, hardness, etc.

Nice job!! I was going to wright something about the mixer, then you made the improvement.

this is fantastic! thank you so much

Thanks. Good demonstration

This is very cool. I've been learning about this aircrete for a couple days now. Great video, thanks very much.

@Prana-Tech, I am not handy enough to do this and am looking for a builder who uses aircrete here in central Pennsylvania. No luck yet, but your videos will help me in my search. Thanks for sharing! Very best to you!

wow really impressed keep p the good work

I'm going with you. great video. thanks.

First I like to thank you for all your informative videos. Your videos are much more detailed and scientific then most of the video postings. I'm new to Aircrete and frankly somewhat skeptical of its durability, but I guess it has it's applications. I've been researching the making of Aircrete by DIY'ers for about six weeks. My first impression was that making the proper density of foam and using the proper foaming agent was the “holy grail” of Aircrete. But several individuals appear to have engineered a workable foam making device and “magic wand” to provide the proper working density. But I'm now convinced that the incorporation of the foam into the Portland Cement slurry is equally important. After watching video after video of people having problems properly blending the foam into the cement slurry, I have a couple of question which I hope you can help me understand. I see most DIY'ers using drill type blenders with sculptured wire blending paddles to “beat the hell” out of the mix. This kinda works, but it appears to be time consuming and has to be destroy numerous foam bubbles in the process. I watched your video of the cement mixer you build with interest. I noticed that your first attempt did not product the kind of mixing action to properly blend the foam into the cement slurry, but that you made a modification to the paddle design that from watching the video had a dramatic effect on the blending process! First, can you confirm that I'm seeing and understanding that your modified cement mixer had this dramatic blending effect? Second, will you share your modified paddle design on you blog, its a bit difficult to see the entire paddle in the video? Third, I have a Harbor Freight cement mixer (frankly which I have never used), would you recommend using a standard configured cement mixer over using a drill type blending mixer to incorporate the foam into the slurry? Lastly, I have to say that I'm impressed with your ability to produce well thought out useful devices. If you are interested in a new project, have you seen the new continuous concrete mixer for DIY. Its called the “Mud Mixer”, (mudmixer.com). It cost about $2999 at Northern tool. It's essentially a small hopper, with in-feed/mixing auger with a controllable water spray and a motor to provide power to the blending auger. Again, I thank you for the very informative videos!

Great video 👍

Thank man... wel done

I love watching air Crete vids

Thanks for sharing.

Thank you! (Hell yes I subscribed, liked, hit the bell - all the things)

I really appreciate the chart, thank you very much...:-}

Very informative

I hope you don't mind that I put you in my Pocket! The past couple of months, I have spent days searching for a well thought out, organized, informative video on Aircrete. Your video is the first one I have watched. No, not fully true. Yours is the first that literally held me captive to the very end...twice! I am a 67-year-old very adventurous farmer lady. I want to build an Aircrete dome home, however, I needed some very solid guidance, from both a practical and scientific standing. Thank you for the time and thoughtfulness you put into your presentation! I have subscribed and have been through some of your other videos. I feel like the robot on Short Circuit, "Need input, need more input!" You, sir, are inspiring!

Thanks, cogitating on that...

I have a suggestion for building walls with AirCrete. Maybe it's been posted and/or tried already, but it may be of use for continuous wall construction. Last year, I visited St Augustine Florida and took a close look at the exterior walls of Flagler College. They were CONTINUOUS concrete walls going up several stories. Apparently, how they did it is, each day, they would pour about a foot of concrete within forms that only extended up a foot. The next day, they'd move those forms up another foot and pour again. Each layer would bond to the previous layer. You can see the lines like strata in the Grand Canyon, each being a day or two old. Call me crazy, but wouldn't that be an easier way to build a wall than making blocks and mortaring them together? If the layer settled overnight, the next layer of foamy aircrete would simply fill it in. Just a thought...

OK, you had me with the TREADMIXER 3000 sticker! I was wondering who made such a cool mixer - where you could use different plastic drums, I assumed. Then to realize that it is just one eccentric guy that builds them. Thanks for your info! Yes, CMX is more powerful with significant minerals present, but their enviro warning...maybe does not apply in your climate. Still learning about aircrete. Thanks!

I enjoyed this very much, and will go through your other stuff. sub'd.

Hi Don, thanks for all the videos. Very inspiring. I am toying with the idea of putting this setup on a tank track and pumping the aircrete out through a nozzle and using it as an aircrete 3D printer.

Thank you for your video. The most informative aircrete video yet. The III cellular concrete class is kinda in the middle. Would that class be good for a tinyhome ICF home with a second story? I'm thinking of building an investment property.

Thanks for the show; pretty cool stuff! How do you make the mixer and how much it will cost if I could order one? Thanks

How much foam do we need to add? How do we know? Thanks.

Good stuff

Hi! Excelent job 👍 we like your video. We made the air crete gun and the air compresor. But Would you please let us know how to make the other things or pieces for our project? We are wishing to make air crete at home🌟. Thxs.

I am thinking of making some self supporting roof panels 4ft by 6ft for an outdoor aviary. I was wondering if you have any suggestions on thickness and or interior reinforcement.

I read what happen to those panels. Have you made any that you could strength test when cured? Very good video and happy you made it!

I like the ideas, just wondering if you tested the strength of of your mixture and how many psi, thank you again for your video.

Hey I have a question. Can you add pumise to the aircrete? I thought of making it hold to a wall or to make molds?

Looks great. You mention the heat drys too quickly, what is the lowest temps to for mix and cure? I'm in the Pittsburgh area and are temp fluctuates as we go into the fall. Thank you agian.

Hi 😃 Thks for the video Do you have any foaming agent you can recommend?

Ok you are on , I am an old geezer as well. However I am working on a 3D concrete printer . The printer has the ability to from a ten foot concrete circle eight feet high. The printer can print various form, shapes . If I work with you we cover two new technologies and build on our efforts. Thanks for the read Walt

Love your videos. I made your wand in an hour. Much better tool. Wondering if you have considered making a pump from the mixer to forms? Thank you in advance. Terry

Hi. I have a question. What Hapen if we mix mini gravel rock in the misture???? enyone try ir ???

I love all of the Air Crete devices you have made. I wish I could get my husband to build them for me, but since he is too lazy, I will just have to build them myself. I haven't looked yet, but have you built a foam generator using a standard air compressor for the air? I already own a very nice air compressor, so I don't need to build that box unit you made. I have seen other people build them, but they don't explain their designs well enough. Maybe I should keep searching. Thank you for the wonderful information.

Dig the mixer! It's been my experience that you can achieve all kinds of density quality's that can be used for all kinds of different applications. Drexel is really good but Dawn and suave can also be used successfully it just can take a greater degree of care to get a good end product.

cured portland blocks that float? How long do they take to absorb enough water to sink?

Good morning, Don. I hope that this finds you and yours well in this devastating pandemic. I'm unsure how I am supposed to add a new message here. Do I make a new query here, or add to the 'replies'? I do have questions. As Aircrete blocks are being stacked, does one mortar as the blocks are stacked? And, how much insulation does Aircrete supply? I live near the Canadian border in northeast Washington state. We can dip down into the below zero range in the winter, with several feet of snow, and up toward the 90s in the summer, but a dry heat. If I need to insulate, what material do you suggest? How do I need to reinforce my dome to support the snow load? Thank you in advance!

Thank you

hey, have you experimented with using lime instead of cement? would be interesting to figure out the ancient roman concrete formula (lime + volcanic ash) as an aerated mix. will play with it when i get the time..

Hello. The link to recipes in description is broken!

What kind of a releasing agent do you need to spray on your forms to allow the air-Crete panels to release from the forms?

Hey, just starting my voyage and wondered... before the foam was added to the mixer you referred to the 'concrete' slurry in the mixer. Was that just water+cement? In the UK when we refer to concrete it is generally cement+water+aggregate (ballast) but I am guessing there is no ballast in aircrete? I would assume that the foam bubbles are essentially acting as the aggregate? Many thanks

What is the right mix proportion of water, cement & foam, and also the mix proportion of foam solution of water & foaming agent

Good day sir.. where did you bymut the earcrete generator?

hello. Great video. Just a thought. I was reading some of the comments about the hard water and the different foaming agents and was wondering if you tested the pH of your water and adjusted it at all, since concrete doesn't like acid.

I would like to make five gallons of air create. Could you tell me the Portland to foam and how much water ratio. I've tried this about 20 times and Can't Get it Right

Looks kool but i would like to see you make interlocking blocks or bricks

Gd am. What the proportion of cement, water & foam you used in your demo?

Very informative. What should be the foam density. Which foaming agent is good.

Aeriated concrete has been around at least 50 years. One of the applications in the 70's was pouring floors in new apartment buildings.

Hi Don. My son and I found your video and have been producing nice foam and aircrete since buying and modifying a mixer. My question is what ratio of products would you use to produce structural blocks? We are interesting in casting 8"x8"x32" blocks for building.

Good

You look to be in Arizona. Nice. :)

Love this video! I am trying to make some planter bases of Aircrete and am experimenting with small amounts, just to get the proportions right. I did an experiment using shaving foam. seemed to work pretty well, but having a hard time getting the ratio, portland cement to foam, right. Your 30 lb/c.f. sounds ideal- about 1/3 of regular concrete alone. What ratio of cement to foam are you using? Or are you just mixing the ratio to a 30 lb/c.f. weight/volume? Thanks so much!

Can you use aircrete to make a floating structure like a boat house or houseboat

Hi, Do you know if you can use rapid set cement for aircrete? And...how would it fare using some kind of aggregate (pea gravel)?? Thanks

Nice video thanks for the information. I plan on building monolithic homes in the Philippines for a charity. Can this product be sprayed to form a dome like they do with the traditional concrete sprayers? Does it have any insulated values? I appreciate any information Thank you!

What if you use wire mesh, can it prevent cracking?

Hy that looks nice, what did you used for the foam?

Amazingly inventive! Is aircrete non-toxic for plant boxes?

Hi Hope you are fine and in good health Great work Sir i want to know the mixing ratios for different densities and strenght. Shall be greatfull for that kindness

Hello. The concept of aircrete began in 1889 when it was patented by Czech Hoffman. So it's been around a while.

Hello just out of curiosity do you know of anyone ever trying to use the white styrofoam packing in boxes that you get when you buy an item at the store?

Hi how much cement you used an d how much water can you tell me please...

I’m impressed that your slab pour did not slump or shrink as I have seen on other KZfaq videos. did it really not shrink at all or was it just too soon to tell?

شكرا

I just got a 3 Oz sample of Vermillion. What is not clear are the followings: for 94 lb of cement and 6 gallons of water for making the slurry, how much water rouse with how much foaming agent and what would be the concentration of foam ? . We need to know the density of the foam? I mean at what PSI the foam generator would be creating the foam to inject it in to my slurry. So, several Q here: amount of foam agent in how much water? At what psi setting on the foam generator? Thank you so so much?

Hello big Dan the gumout man. Just kidding fella. I really like the way you are measuring foam density. What I would like for you to get back to us all on how the other foaming agents worked out for you fella. Also, would adding acrylic to the mixing of aircrete make for a more water resistant media for the job ??? Please get back to us on KZfaq so that we all can learn from one another. Thanks VF

What was the density on the second, CORRECTLY MIXED batch!?

do you have a video on how to build your foam tool and set up? a video of your mix concrete slurry ratio how much concrete how much sand, if any? how much water??? what brand concrete mix do you use???

I know this is an old video but what if you replaced the water with a cement adhesive? It might produce a stronger aircrete.

how much cost would it be when i use (600mm x 3000mm x 100mm) mold? and raw material mixing ratio?

I am confused about your measuring cup. It is 6.112” diameter, but you said it has 6” across? Isn’t diameter same as across? What is the length”? Thanks

If you angel the mixer blades it will increase the mixers efficiency.

can you add rebar to aircret?

very cool and thx for the info. is that a rammed earth building behind you?

Gr8 video, have U heard of styroaircrete?

Have you ever tried any fiberglass, epoxy or graphene additives?

Looks like Tucson, Az

Can you add dye to the mix?

is it strong enough to make a full size house with?

In our experience, the density of the foam is way more important than how much foam you add. Less foam makesthe aircrete way stronger. We'll be showing our test sample results soon. We have huge temperature swings where we are in southern Arizona. We are mixing at about 80° in the afternoon and getting down into the 30°s overnight. We leave the aircrete uncovered until the next morning, which has worked out fine. Did it work to cover it, & did this panel turn out? Maybe you show them on the next video, I'll check. 🙂

What is your concrete mixture formula/recipe before the foam is added.

Aircrete was invented a very long time ago. It was used in East Europe about 50 years ago in reinforced concrete buildings as an insulating wall. So it is new in US but very old in Europe. Best regards, Tony

So how much and what type of concrete mix do you use

Hi Don, good job! I think I have something that could be developed for greatly purifying the water and could help a lot of people. Do you have an email or website?

36 thumbdowners more that need help. Good video.

Is there anyone in Arizona that can teach me how to mix right consistency and equipment I just want to make small projects

Can you use a regular concrete mixer? Or does it deflate the mixture?

use a large paddle mixer and use it in reverse. tis will bring te cement up to the top

Hi Don, In this video you used Drexel F-M160 but in your "Aircrete Foam Generator Machine DIY" video you used CMX Foam Concentrate. You've said you like both of them, but in each video you seem to prefer the one you used in that video ... so now I'm confused. Can you perhaps point out which features of each you like best? Or is one nearly always better, and if so which one? By the way, thanks for another great video! :-)
