Aircrete Experiments with Low Cost Foam Generator
Вставка
- Опубліковано 25 сер 2018
- This video shows how you can experiment with aircrete under controlled conditions at a very low cost including the foam generator.
I forgot to point out that the weights of all four samples were within 5% of each other. The difference is errors of measurement and the weight of the foam used in each sample.

I have watched a LOT of videos on aircrete here on youtube, and this is by far and away the very best at conveying information that has value. Excellent job well done.
Best video about aircrete I’ve seen yet. You’re not hawking anything and you’re deliberate and organized. Thanks for sharing.
That balance beam for making the ratios work is damn near genius. Thanks for sharing that.
The math was awesome, the idea of using shaving foam brilliant, the humor subtle, presentation dry as the Mojave. Standing near a field being dusted not so good but was kinda neat to see.
Yeah I was thinking he doesn't wear a respirator around Portland cement dust so what is a little crop dusting? Guy is brilliant though.
I appreciate the steps taken and the final call of the video to encourage others to experiment with other variables. What a fun way to work together by sharing an approach others can use, and providing great result analysis which can be replicated by others. Thanks for taking the time to do this, Mr. White.
Well done! It is so refreshing to see Aircrete experiments that are thoughtfully designed, carefully controlled, well measured, and documented!!!
This entire 5 part series is amazing. Great information on techniques, testing and summary information. I hope to do some AirCrete an water glass experimentation on mixes that would hold up to a Rocket/Mass Stove. Ideally 3D printing forms for a small aircrete stove cast.
Thanks for the kind words. Please make a video about your sodium silicate and stove experiments. I think a lot of people would be interested.
Dear sir,
Thank you for your excellent methodology in conducting your experiments, they are greatly appreciated.
Please keep up the good work!
The world needs more great teachers such as yourself!
All the best Marios.
I think the balance beam is an interesting demonstration of ratios and relevant to the ability to make repetitive measurements for testing purposes.
(One could as easily tare the container for the cement - fill it - take that weight divided by 1.88 - tare the water container and fill to required weight.)
The math to arrive at the placements of the 2 vessels on the balance beam was also a useful demonstration.
Where I became doubtful was when the 2 'tare' weights ( bolt and eraser) were introduced (9:30).
It's necessary to assure the 2 vessels are of equal weight - but when the bolt and eraser were set on the balance beam and moved to level it - in affect it made the cement and water to be equal in weight and canceled out the 1.88 ratio previously determined. The weight of the bolt and eraser should have been cement! Pls help we to see what I am not understanding.
Thanks for the demo for just beginners with Aircrete.
I so appreciate you breaking down the amount for small batches and your shaving cream for foam saves me buying a compressor! I wanted to make small batches for sculpture casting. Excited to try and see how it turns out!
Thanks for posting this video! its amazingly good info, and I appreciate you are so willing to help and not trying to sell stuff! thanks so much!
Your research on this is very much appreciated, Sir.
Many Thanks,
Wulfy
Wulf Claw we like all the same videos lol
If you had been my science teacher, I may have understood what was in the dry, dusty textbooks and gone to M.I.T. I had the aptitude and the grades. Thank you very much for your knowledge, time and patience.
Just what I was searching for.
You are a great and caring teacher.
.Best aircrete instruction and information I have come across for anyone wanting to experiment and plan projects. Will watch the other videos. Hope to post a few questions later then tackle some projects.
My ADHD was resisting the speed of this experiment but your perfect instruction kept my attention.
Thank you so much sir! This makes it much cheaper to experiment! I'm going to try a small batch of foam with a tiny bit of SUAVE and a good blender! Might be cheaper than canned foam! Anyway might I point out that any good cook would tell you this - get your self a good rubber spatula!! It will work wonders for cleaning the sides of you mixing bowl - while you're mixing! Nothing will remain unmixed!
Great information! I appreciated the thoughtfulness of how you can transport cement in smaller quantities. Helpful if you want to save your back! Btw, Pampered chef sells that set of strainers for a pretty penny! Great find! Can’t wait to start making aircrete!
Every step in the process you identify problems and present a solution to test. Really good stuff
I love the detail. It reminds me of "Old School". It takes more to absorb, but tells everything to succeed the very best...but i need a text book to follow, with this detail. Or maybe a workbook that can be assembled and offered to have valuable tables and charts to refer back to. I appreciate his teaching method of reason.im sure there are many experiments this guy could instruct on. I loved this video. thank u
Great. Thank you for taking your time for such precise video .
😂 love the shaving foam machine you used, and the detailed explanation of the video👍🏻 great job.
Old fashioned science, very nice. Thank you
Best video ever. Thank you for sharing 👏
Excellent video. Everything explained with scientific reasons. You remind me of my dad who was an engineer and constantly experimenting with precision with each project. Nothing was ever arbitrary or haphazardly done. You are the best. Please continue to share with us. We need explanation and demonstration of your caliber.
i think jim explored something other aircrete experiments did not: making small amounts with dense foam from shaving cream is an excellent way to explore simple comparisons AND feel the difference! good video! (i merely forgot to say this in my first comment)
Classic old timer engineer... Reminds me of my grandpa! I love this stuff.
I like how you showed a lot of detailed information on your findings. Thank you.
Data nicely explained and displayed. Thanks.
Very nice explanation thank you and May God Bless you and your family Greatly you now have another subscriber
Very clear and concise demonstration , It has made the mixing ratios much more understandable to us lay people that skipped out of to many math classes
thank you sir it has helped me a great deal in trying to make some kind of sense
to making a strong , reliable aircrete recipe that is also consistent for construction use
Thank you for sharing this knowledge Sir
Hey Jim thanks for sharing your time and efforts besides great knowledge ,what about if adding fiberglass fibers that comes like hairy spikes would that double or tribble the strength? thanks!
Thank you very much, Jim, for doing cool stuff. That balance bar is as simple as ratio weighing gets! Keep doing and enjoy!
Thanks for your comment. Best regards.
Nice work on trying to get standardized measurements for aircrete applications. I would say that your shaving cream is as close to the best density of foam possible. An ideal foam weight by volume is suppose to be 80g/liter. I wonder what shaving cream weighs?
Great video! I was wondering whether anyone had considered using off the shelf shaving cream and voila!
This is a great video experiment with a quite possibly very up and coming product that could potentially help change how we view concrete and insulation. Thank you for your attention to details.
Thank you for your kind comment.
Love the added comedy... "oh no, he's coming right at me. I'm gonna die!" Haha.
Thanks for the video. I love the DIY lessons. I've found myself taking notes!
Great video, thanks for your work . The Barasol idea is so clever !. I think to try emptying a can to see how they introduce the liquid ?? Ventori ? and copy it or use the can s internals over and over again. the density of the foam I wounder about.. Another very interesting idea you mentioned was the longevity of the foam ?? AND how much volume is lost durring the mixing into the cement slurry. Now ya did it ya got me going thinking .Thanks again.
Great experiment Jim. Thank you.
Good evening dear Mr. Jim White,
My name is David Espinoza, I am Venezuelan, and I have seen and reviewed my innovations on, cellular concrete, but I have time researching but in Venezuela I could never get the necessary additives to achieve a good formula
Now I have detailed everything that you do and I see that the cement and foam are that you use are very uniform and compact, which are kept very omogenea, you put to the cement some additive that allows the catalyzing of the components.
Impressive math skills!
Simple, clear and easy to understand. Good video. Thanks Mr. White
Excellent information Sir!
Thank you for taking the time to present your findings in a succinct manner.
Just want to say, wear a dust mask to prevent breathing in the dust when sifting and moving between containers. Portland cement isn't the best thing to have in the lungs.
And where you can, limit its exposure to the open air. It the calcium oxides reacts with the CO2 and moisture in air forming calcium carbonates.
Thank you so much I really did need a formula for the aircrete. I understand it very well long as I'm watching you do it I'm not going to even say I understand the formula because I don't. I can go back and watch your video again until I get what I'm doing right. Thank
Thanks for your nice comment. Best regards.
He is an inspiration, I'm interested in aircrete ,this is the first video I saw which is scientific, most are a bunch of speculation and wild guesses
Thank you for your kind words.
Well Jim I'm glad you did these test because there is a lot of misinformation about this method of building with aircrete that is just dangerous to even attempt.
It will have its uses such as insulating but not structural.
Thank You for the education.
I have no knowledge about all these, however, you explain everything so we'll, even I get it. Thank you so much.
Jim... Thank you so much for the effort you put into this video. This was the information I needed to know!
Excellent instructions ...can you tell me weight of portland you used for these samples i seemed to have not written that down... also how long did you wait for the 3 part foam sample to cure before you did float test? i am going to store and get supplies to do this...this material is just what i have been searching for ...Again best teaching video... i already was going to try shaving cream myself,so when i came across this video i felt i hit gold...thanks again!
Thank you for this video,explain very good, and que you show the foam... amazing!!! And the airplane... 😅👌🏻💯💯💯 I apreciate a lot,best regards from México 😃
Excellent presentation. I wish you could also measure the strength of various ratios of cement over foam or the like.
That 1.88:1 balance contraption was pure genius.... I don't think this sort of thing has been taught in a long time (simple levers, yes, but nothing about tare weights or practical usage)
So as I see it it is 1.5 cups of cement, 1 cup of water,and 7.5 cups of foam, that's what I am going to do, I have tried once before, but did it kinda by eye and came out with bricks ,but you could break in them in half quite easily, a torch test was positive so that by holding the brick in your hand and applying heat from a gas gun you felt no heat transfer . thanks for your vid,very informative
i was just wondering how aircrete can be fossil fuel independent, without needing any electric grid equipment. And voila! A thought about "shaving cream" came to me and I searched for "shaving creme concrete" to find this video. Very exciting!
This was very interesting, thank you.
Very educative & informative . Thank you ,sir, for your excellent explanation.
Would be interesting to see comparison of strength between the samples after fully setting of the concrete (2 months?)
great details ,science always wins . PS:try mixing cement first then adding water
Liked the video. Then I got to the balance...subscribed
Thanks for your video Jim - it was helpful.
"Once you get it home, the fun can begin"!
👍🏼👍🏼👍🏼👍🏼👍🏼
This video is so helpful to me thank you.
Congratulations, You explain as smart, with procedures and math. Thanks You, la once of they first videos that i see this.
Thanks Jim! - I've seen several videos on making foam machines - but you've shown me a ready made machine I can get from the corner shop(that's a 7-11 in Wales, UK!)
I like the humor plane part. "... whose gonna finish my video?"
Whats the compression tests of the aircrete? How about submerging the 3 parts to 1 underwater for 24 hour or longer test, then compression testing. Then heat testing the aircrete. If all works out, that's all worth investing in!!!
my 3rd coment at the beginning of 2021. If the man was young i would say he has a bright future. But i dont know what happend to him by CORONA VIRUSES. I hope he is alive and see my comment..
A nice master. Thank you OSTAD.
I love the smell of Barbasol shaving cream, I got for a dollar is almost 7 dollars on Amazon July 2020!
Finding a way to mix thouroly with minimum agitation would increase volume.
A ratio of 1.618 would be interesting.
Adding a small amount of sugar may help or ruin the bubbles.
I have known two other older engineers of your caliber and had the opportunity to work with them.
I wonder if the bubbles expand as they heat in the weather, or chemical reaction.
Jim -- great video -- have you come up with a mixing chart that we could use to make small batches of aircrete? I would like to make an amount to fill a form 2 feet x 2 feet x 2 inch's thick. Thanks
Thank you for sharing, very educating, thank you and have a good day
And here I thought I sold the most affordable foam generator lol. I don't think it ever occurred to me to actually use shaving cream. Nice!
Great job with the experiment!!
very impressive testing procedures and analysis. What is your operational definition of an "ideal foam?"
You're the first one I've seen use barbasal.
Excelant
Thank you very much for sharing!
So this is what old dudes do in their garages while in retirement?
🤣👍✌️ Great! TY
I don't know what old dudes do, but this is what I do. LOL. Thanks for your comment.
did you do strength tests ? also would heat treating them strengthen them much with added clay ? the quest for strong super light bricks even for insulation.
Thank you, sir. Could you please, redo the same test, when the air-creat is fully cured.
Nice! Simple and clear detail.😃🙄😏
I'm interested how frangible the samples are?
You could use a flower sifter for the lumps.
can u help me . how make air concrete in our country for blocks like bricks for buildings and i want for sale by cheap price . can i use poly styren fom for this air concrete or is other fom
Maybe I am not understanding something. If you made your measure for L1 = 10 inches then the measure for L2 should be 10.88 inches that would make L2 the longer moment arm not the shorter arm ... But I am seeing it as the shorter moment arm. Please confirm - thank you .
In you're test you should include how durable they are. Try to make some damage to them on purpose, so we can see if they wort to make
Lets say i wanted to make a 1/2 gallon of aircrete to fill a vase? how much port land cement is needed? and could i just buy a can of shaving cream to mix it in the cement mix??? and what is the ratios? lets just say i want to make a cup of aircrete... can you tell me how much cement,water and foam is needed of each... i am good at math...just need ratios as close as possible... i can experiment and get it right... thanks
thanks jim I enjoy your videos
That bag of portland was old. I've been working with cement for years and only old or cement that got damp would have lumps in it. Great video!
Thanks a lot Sir Respect For u Done
Thank you Sir. Very educational.
Great Info... When will you be doing tencil strength testing ?
@@Jimscoolstuff
I bet you are Jim, and I also bet you will succeed. Thanks for an interesting video.
So it isn't really a foam generator, it is a dispenser of foam you bought. I guess I am not very smart...I can't figure out how suspending the blocks in water changes the weight of the water in the container to give you a volume measurement.
Has anyone ever questioned what can happen or will happen over time with soapy foam impregnated into the concrete?
I did not expect that airplane attacking you! LOL
I wonder why you didn't fold in 7x the volume of the water used in your slurry? Seems others use the full bag of portland with 6 gallons of water into a 50 gal vat, with 6 gallons holding the cement, should have left 42 gallons free, thereby asking for 42 gallons of foam to be introduced, so in your experiment shouldn't we have input 7 containers by volume of foam? or somehow converted the volume and made a mark on the container side to be the measure for foam?
@@Jimscoolstuff Another variable is the amount and aggressiveness of the stirring to incorporate the foam. These can dramatically affect survival of the foam bubbles within the cement. Every aircrete experimenter needs to recognize these two variables!
Load bearing up to what amont psi and psf? Looks fun. Thx.
Clever measuring device
Excellent work. Could be interesting to use sand
