• Aircrete Foam Generato...
Just checked Rural King and the price has increased by 38% since this video was made. I just ordered 4 gallons on 5-24-2020 for $24.99 gallon. Still best price I've seen so far.
This is great. Really cool to see someone bring rigor and organization to these aircrete experiments. Thanks for sharing.
By far that is the best foam generator I have seen
Kudos on being thorough and patiently going through the steps. Yes, Aircrete definitely needs some real research to realize what we can and can’t do with it
and how to get a good usable product with real value. Thank you.
I like the white lab coat, the science behind aircrete, and your experiments are informative. Thank you.
Jim sir, your build is so well made, everything nice and tidy, and easy to use. Nice to see a properly built unit.
This is great, I’m a science teacher and considering using your videos with my 6 th grade class. Keep it up it’s a perfect demonstration of the scientific method.
jim white
I’m glad to hear it! You tube is a great tool and learning from the people that take time to share information has opened my eyes to possibilities that I didn’t know existed. That is just the lesson for a 6th grade mind on scientific inquiry and your methodical approach is perfect.
Great idea to use compressed air to drive the foaming solution, then using a needle valve to meter the fluid. The simplest solutions frequently are the best.
Two things of note:
1) I looked at the safety data sheet on Drexel's website, and it seems to be fairly toxic with all kinds of warnings about exposure. Please be careful when handling this stuff.
2) To state what may be the obvious, 1 oz of FM 160 in 5 qts of water will yield a perfect 1:160 ratio.
Enjoyed the video. Thank you for posting it!
Professor White!!! You really have a great set of videos here. The numbers, explanations, all very thoughtful.
I think I have decided on your system, and forget the others.
Thank you sir!!
Thanks for the clear presentation Jim. If you want to compare the aircrete compression strength at all with typical concrete, the specimens would want to be cylindrical at a 2:1 aspect ratio - such as 8" tall and 4" diameter, to compare apples with apples, but you probably know that.
Thanks , Jim . There are other aircrete how-to channels but they lack something in organized presentation .
Please don't take any of my comments in a negative manner definitely not my intent. And don't let any feedback discourage you.
Viewing many of those who made the foam generators - yours is by far the best no negative remarks at all absolutely 100% best no hesitation no doubt. I especially like the idea of design in that you have a free hand only holding wand with the one hand.
Awesome. Thinking you might have in your life been a professor, school teacher, or employed in field of experimental science.
In any capacity you must have been admired, respected, and successful. Thank you ever so much taking time to make your videos.
Hi jim,
I appreciate your Video.
You can bring your efforts on higher level by NOT using detergent but by using hydrolised Keratin as a foaming agent. The great advantage of hydrolised Keratin is it allows you to lower your the water/ cement ratio a lot. Use plasticiser or super plasticiser instead to reduce water. FYI water decreases the FC quality a lot.
How to make hydrolised Keratin foam concentrate...
Basically keratin is finely shredded/chopped cattle horns and hooves, pig bristles and chicken feathers. These are commonly used organic fertilizers and cheap too.
Make a 2,5% sodium hydroxide solution (lye) And heat to 70 degrees C.
Put in the shredded keratin and stir / agitate constantly. Ad more keratin and agitate Well untill saturation. Filter the remaining solids out of the solution and discard. Neutralise solution with acid to approx pH 6-8. ( e.g. Muric acid does the job)
Optional:. Ad some ethylene glycol for winterisation and preservation against decaying / rotting
Now you made the best foaming agent ever!
Caution: working with lye is very dangerous. Ware skin and eye protection covering. your eyes/ skin completely. Keep spectators / kids /animals away wenn cooking your "brew". Cook Outdoor because of developping smells... preferably cook. when your
neighbours have a Garden Grill Party.....and the wind is towards them ....lol
Before foam concrete production, dillute the foam concentrate (a brown liquid) with water in ratio 1:40. Produce foam with foam generator as usual.
Ad superplasiciser to the water cement slurry. Reduce water cement ratio as far as possible. Ad the pre formed foam and mix carefully.
Thus produced FC will be light weight strong and durable. It will have excellent insulation properties.
Optional: ad lime to the cement slurry. 50-50 cement- lime will increase strength and elasticity. By adding sand you increase spec. density and strength even more, but decrease thermal insulation.
Now you brought you FC skills on a higher level.

Wow higher level it's what I need respect españa
I followed the method used by the guy on the mantools channel. No compressor or wand needed. Just mix your soap and water ratio into a 55 gall drum and use a drill and paint mixer to make your foam mix. Very simple and effective. My problem with the aircrete I made was that the end product is too fragile for most uses. I made blocks for a raised garden and found that the blocks cracked badly as they aged (within months) and that my weed whacker chewed it up very easily. I’d be interested in hearing if your experiments had the same result.
as others have said, a pleasure to see a more precise approach to the subject matter, Thanks and I think we all look forward to part 3
so you want a wheed wacker proof foam??? lmao! thanks - saved my day!
super demo you forgot to adjust the water feed for the drexel at 50psi.. excellent demo .
Jim, please try adding 3% of Glycerin to the mixture you make here, it will produce a luxurious rich thick foam ! It will also make the produced foam last longer !
Sodium lauryl sulfate.. Is what is needed to make great foam
@Rajko 1:40 ratio 1 part clc foaming chemical with 40 parts of water.
When will the US go to the metric system...cups gallons lbs. Nightmare
Jim, I’m afraid you missed your calling. You should have been a teacher. Thank you for making where I can understand. Great video. Thanks again.
This is a realy nice system to make foam, thanks for your valuable help.
I like how you broke this all down to making an exact science. 👍
Love Jim's approach. And what a good argument for going metric.
Not really. Thinking carefully about things is not bad.
Jim, Great work, thanks for taking the time to make a very informative video. Looking forward to seeing the rest of the series.
Thank you for sharing, Sir with the outmost respect I must
say you reminded me of my brother, he is chemistry professor and I enjoy asking him questions, he will go
into details just like you, thank you and have a nice day.
Wonderful to watch your vids. I want to make a foam machine and try to experiment with foamcrete. For a handy ml measure and dispenser, a 35ml or 60ml syringe can be bought from a farm store like Tractor Supply store. Put a short piece of 1/8 vinyl tubing on the end if prefer extension.
I like how you’re testing all this, and thank you for sharing. I’ve subscribed because of your meticulous method.
Thank you for presenting this information in such a pragmatically logical and well considered way. Very interesting results.
hi Jim, great videos and good info thanks. i have used similar method with some additions with amazing results. us 1 to5 ratio of dawn with pva glue and 10 to 1 ratio dawn with shaving foam. mix together and add solution as per usual. The pva glue wraps around each bubble and gives it more body as does the shaving foam. 24 hours and my foam is still at the top of the bin!
Just stumbled across your vids while researching. Wow excellent explanations of everything even a 6th grader could follow. Thats impressive. You dont make the audience seem stupid which is a plus also. I am subscribed and looking forward to your next aircrete vids hope the wait is not to long lol. Godspeed.
Love the design of the foam aggregate. And the presice deskribsion of the soap to water ratio thanks
Here we see the endeavours of the world's leading foamologist. You really only can get this kind of content on UA-cam.
Ok, now I'm officially hooked based on your clear, concise narration and excellent methods - but now I feel like I'm waiting for the next Bond film.
I can't wait to see how your aircrete experiments work out, and pray you'll: a) work with & test aircrete as an insulation, and b) come up with a mixture and a delivery method that DIYers could follow - even if you set up an Esty store and charge for the plans, formulation, etc. Professional insulation installers are pricing foam-based insulations (including aircrete) out of the reach of the vast majority of homeowners.
Im enjoying your scientific approach to working out the optimal ratios. One thing I wanted to mention for you to consider taking into account is cure times. You might make samples and controls that have longer cure times to evaluate how that effects strength. I have subscribed to watch your progress.
Thanks for the video, I like the way you go step by step and explain it very well. I like the foam generator very much. I make cement planters and other small items with cement. I would love too see a parts list or a video about the foam generator. My wife has been after me to make one so we can make some light and stronger planters and Thanks again for the great videos, keep up the great work.
Hmmm.... nice wand and vertical foam generator set up
Great job! Going to make a foam generator like yours.
Great design on the foam generator!
Thank you for your reaction.
The Drexel foam concentrate is based on 2- butoxyethanol (chemical)
My simple step by step hydrolised Keratin receipe, is self explaining to everone with common sense. making a Video of the process is not really needed and takes time that I do not have. Just follow the description that I send you, it's simple as s...t.
By the way, instead hydrolising Keratin, you can use dried blood fertiliser too. (Slaughterhouse waste and commonly used organic fertilizer) This would avoid the grinding/chopping of the raw (and yet cheaper) Keratin.
Both the hydrolised Keratin and the hydrolised blood are excellent Protein based foaming agents harmless to the environment.
The Equipment needed for the hydrolises process:
*oil drum on a 3 stone woodfire,
*Drum or liquid container
*Filtercloth
*electrical agitator,
* Pressurized waterhose to fill the drum and as a simple stand by safety shower.
Personal protection.
pH paper strips
I suggest to start your very first batch with a bag of bloodfertiliser , since grinding of the raw Keratin requires a Grinder mill.. the blood fertilizer is powder like
In case of question, do not hessitate to ask

Is Hydrolysed keratin available commercially? Not being a chemist, I would prefer to purchase it if possible.
@@skepticwest9628 yes it should be commercially available but i do not where in the US or in other countries.
I always produced my own to reduce costs.
Great job Jim. Thanks for sharing !
fantastic vids, and looks like youre having fun with it! looking forward to part 3 :)
Very nice foam generator! Ive seen a variety of systems but yours is in my opinion far more superior to the others.
This could easily be scaled up for larger production.
What other system for foam generator
Thank you for a great lesson, easy to understand, 👍👏🙏💖
12:45 thanks for converting it to a measure, a normal human beeing could read!
great video!
Sodium lauryl sulfate.. Is what is needed to make great foam
@@Jimscoolstuff I have to thank you for using metric system too, and I hope this helps people understand why it is best to work with
Can you please experiment with the aircrete using concrete bonding solutions? When I used to texture houses I would add an acrylic bonding solution and that stuff would make the texture really hard and strong. I know there are a few masonry bonding Solutions out there.
for example ! once we have (if you have provided by manufactured) the amount of dilution for that x foam agent ! the thing is like that ! probably by cement setting time we should be on the right path if the foam density is 100g/liter volume or more !perhaps we should understand the economical side of dilution and air ratio as well for another one ...but again we deal different global zone and different versions of foam agents and different prices as well maybe for the same agent !also we should think about cheaper or affordable agents to start from and trying to understand cheaper additive as well for them !
wow I love your channel and experiements! great content!
could you please make a video of how to build a foam generator 👍✔
That does look like a very well engineered little generator he has there.
Jim, great easy solution for a foam generator.
Concerning the foaming liquid, how may that “foam used to extinguish fires”?
Don’t know, just recall that the foam sprayed by firefighters seems to remain foamy for a long time... just a thought 💭
You could use a 20 or 30 ml oral dosing syringe or slip luer syringe to measure the small amount of liquid.
Thank vou Jim the experiment s are really good
Really good idea .
Like the research, please consider Hemp bast hemicellulose as a organic multi layered nano fiber as rebar reinforcement
Thanks for your suggestion.
have you tried adding glycerin to the foam mix? Would that help the foam hold it's bubbles longer? Might be a good experiment.
Ok want strong foam ..mix expanding closed cell foam with cement and krystoloc which is what they put in dams and pillars.kystaloc makes concrete harder.you can drive a car accros it if you make a light bridge across a creek if you ad rebar.and you can haul the bridge in 2 peices on a trailer
Keep up the good work Jim!
Looking forward to more videos!
BP Comprox was the best strength detergent - I guess you can find any US gas station carries an equivalent
Thanks a lot Sir U so inspired
I loved your videos. Thanks.
Hello there, Jim. I appreciate what you're bringing to the Aircrete table. I'm glad to see someone qualified to run tests on various mixes to determine strength. I'm looking forward to your next video. I'm new to Aircrete, but I have a question. Instead of going through the trouble of making Aircrete with foam, why not just use a bag of cellular cement? Is it a cost issue? Because purchasing a bag of cellular cement appears to be a lot less work, and they have all of the test data for that cement.
well done, now sir the plans to build your generator this is the one..from australia..joe
Me hopes U B enjoying yourself in doing these efforts. I will put your means and methods to work. I always learn something unexpected from each of your vids. And me mate, that is a very good compliment me thinks. Cheers. Good on ya.
you need to add sand and aggregate of some sort to the cement to make concrete, and aircrete i assume needs similar additions to the cement. cement alone is not very strong.
Nice job!
Thanks for the lesson u r awesome sir I thought you were slow but no just right teach me to slow down
Another thing that i read bout foaming agents is that the thicker the agent is the better !because we might end up using a little more air pressure or a lower rate production but the overall the thicker the agent is and on a lower rate dilution we produce (end up having a more stable over time foam) again in my simple words! seems that the grain and quality of the foam overall the size of bubble we might end up somehow controlled by the iron mesh of the machine !still we left with the internal resistance of the foam in time ! sow if it s not so great we might end up using a additive that set fast the cement ! still the foam agent and aditive SHOUL BE CHIMICAL NEUTRAL !Seems to be more a ionization then a real chemical that we need here !
Thank you for your comments. I have not been working on aircrete lately because of my disappointment with the low strength and the fact that it absorbs water. Your ideas are very interesting. It would be nice if you cold try your ideas and share your results by making videos of your experiments. Best regards.
Great video! :) Glad I stuck around!
Thanks for your Tutorial
Jim - are planning any additional videos on aircrete? I'd love to see what your take is on the insulation value of aircrete, as well as the right mix for insulation purposes and an effective delivery method.
I want to build one...are there free instructions available for this ? or do you make a video on the build? i could probably wing it,but this thing you made kicks but making foam and is just what the doctor ordered? any help is appreciated ...thanks

Jim, thanks for your work! Do you have a schematic for your foam generator? It looks very efficient. I would like to build one and follow along. Thanks. Phil Yeager
Thank you, Jim. Much appreciated.
Will a 6 gal pancake compressor (2.5 cfm) be good enough for the job?
I looked to see if you have a video or list of parts used for your foam generator. I really like your setup
Jim...Try adding a Mid Range Water Reducer to the Portland as this is used for stronger concrete as less water means stronger concrete
Once I saw Jim in his white lab coat and knew he had a Ph. D in aircrete.
Good morning, could you change Drexel and use 99% sodium sulfate for foam generation? what is the proportion of sodium sulphate to water?
It's just 4oz of Drexel fm-160 for every 5gal of water.
.8oz/1gal == 1oz/1.25gal == 4oz/5gal.
Thank you mister jim
Greetings and Thanks! I am wondering if the Drexel Product is safe, as I do not trust Big Agri. I look forward to seeing the results of your compression tests. However, as I am considering this product for an upcoming project, I would be more interested in the results of thermal and buoyancy. I would like to build a storm shelter dome and put your formula to work at a scale that may benefit humans.
No one seems to mention but air pressure and pvc is a bad mix there are alternatives , that are made and safe for air pressure !!! Just want to put out a safe alternatives,
Did you figure out the density of a particular aerated concrete recipe mix? Please repeat the recipe mix and see if the properties and density are repeatable. Thanks
Hello!! I love your videos! Do you have a list of the items I need to buy in order to make a foam machine (plus the video if possible) thanks!!
It seems like the key thing about bubble longevity is that it only has to maintain its structure until the cement starts to set....anything beyond that doesn't matter. I'm not sure why it would be "far superior" (just because others say so), since there is no information about how long it lasted in relation to concrete set time. Also the number of buckets is irrelevant when the valve setting may not have been the same with the other detergents. I thought he said he got 2 1/2 buckets out of the other foams, while only 1 1/2 out of the Drexel.....?? not sure that is good science or logic.
I seem to have missed the part where the three different recipes are shown. Can anyone tell me when that's covered?
Jim, Great video and information. Can you tell me where I can get a small Eductor fitting like the one you used for your foam generator? Thanks
Great job 👍
Hi Jim , thank you for sharing your experiments. I just subscribed. I was just wondering if anyone has tried any waterproofing additive. This would broaden the usability for me. If you have seen anyone trying this please forward. Looking forward to your strength test. A fiber addition would certainly be a good choice for strength and durability. I’ve added fiber many times on large pours over the years. It would be light weight as well. Thanks again Jim.
Why do you need an eductor when your tank is pressurized? Is it for suction purposes or for mixing purposes or both?
@@Jimscoolstuff thanks
nice foam!
Do you have the plans/instructions for the foam generator and gun that you made?
The title of your video is "How strong is aircrete" so I did not hear or see the compressive strength of the aircrete, what is it?
wondering where you picked up your fluid inductor and was is expensive? Is it essential or could one use a check valve to prevent back feed; given if that is even an issue..
@@Jimscoolstuff a home-made venturi of a sort. So it seems the position of the vortex through the tee is close enough to pull the liquid and not cause problem pushing the fluid back down the stand pipe. which it probably shouldn't because the same air pressure is pushing the fluid into the stand pipe....interesting. thanks I will have to give this a try.
THANK You do you planning to sell it I want one
Thinking if you double the amount of solution you should make much thicker foam tight
Glycerin idea from james seems like must.
Is it possible to have a bigger mouth on the PVC pipe?
How do you mix the foam with Portland cement.
You're using the wrong Suave shampoo.
The one others swear by is the "Daily Clarifying Shampoo" from Suave. Different ingredients.
Can I make a foundation for a garage or house
Sir can i make bricks and tile and use pigments colors with that? replacing sand and use that foam instead ,I enjoy watching u videos here n central Mexico God bless señor
Hola Antonio. I've seen Honey do Carpenter use a liquid pigment added to the cement/water mix before adding the foam, he used a Terracotta like color.
Good Luck with your project Paisano, I'm originally from Chihuahua
@@inarafiredragon01 ok paisana (o)me imagino k puedo usar powder pigment colors is all they got down here irapuato Guanajuato gracias por El tip
@@antoniorodriguez263 Tan hermoso que es Guanajuato, me quedé enamorada de tu bello estado.
Two important things to remember is to reinforce the structure with a plastic fiber mesh and bind it with very liquid cement mix as you would do with an Adobe house, also seal the Aircrete with some kind of polymer so it doesn't deteriorate.
How to make this foam gun ?
