How to Build a Simple Aircrete Machine

[@blindorize]

Hey man, great video! A couple tips for you, though by now I'm sure you've started doing research and have come across most of these already. 1. The foam needs to be as thick/dense as possible, like shaving cream. If it's airy like that then the cells are too big and not nearly dense enough to hold your cement together. You can try Dawn or 7th Generation soap from any store, or order Drexel Foaming Agent if you're close to a Rural King. It could also be an issue with the design of your foam gun, or both. 2. The proper cement to water ratio is crucial - most are finding that 6 gallons of water per 92lb bag of cement is about right. That comes out to about 8.1 oz of water per pound of cement. 3. Have the foam gun primed and ready BEFORE you mix the cement slurry. You'll want to add the foam in to the slurry immediately. 4. Your initial goal should probably be to double the volume of your cement. That means in a 5 gal bucket, fill it about 1/3 full of cement slurry, then double it with (high quality) foam. Good luck man, I love seeing all of this in action!

[@fiveforachange7997]

Thank you for the info as that's the hardest part to find sometimes! I'll make a video of the mix and go with your recommendations. I think I also need to put stainless-steel wool in next time and more of it to help create more of a foam. I did use Dawn Dish Soap but I think the Drexel would be the best option. I could only find 7th Gen online so that's why I went with Dawn to start. Thanks for the info!

[@fiveforachange7997]

Ok, pinned it :)

[@blindorize]

Happy to help! Will be anticipating your new results.

[@JanColdwater]

There is nothing I like better than comments like this! Adds to the video and knowledge in general. Thanks for teaching!

[@kolinevans9127]

just based on my so far few hours rudimentary learning and now your video - i think if you can add a small {possibly adjustable} in-line liquid pump to the section adding the mixture {i.e the pump should be pumping the mixture to the gun} this would be the path to gain a thick foam - you might also be able to experiment with the material in the gun - it just makes logical sense that if the foam is too 'airy' this is not really due to the mixture and it is due to there not being enough injection of the mix material - the other design "little dragon' it appears seems to have an in-line pump it seems logical it is to add more mixture - the key would be in being able to adjust it - i think any in-line fountain pump or even adjustable fish tank pumps might greatly increase the quality of the end result, i.e a thinker foam material which would in turn solve your issues with the weakened structure. thinking more about it - it would likely solve the 'sputtering' issue that seems inherit in this particular design - of course if yu are then actively pumping the mix you may want a larger container holding the mixture - the end result would be fairly similar to the previously mentioned design however - all these principals are fairly simple so i think one could make a fairly effective hybrid - thanks for sharing the video - i hope this might help someone. I may try this myself as it seems like a good general building solution especially related to ICF structures where they are primarily used for forming and insulation, one may be able to make a brick form with just two {or just one} small hole in the center to allow for a binding reenforcement - if you look at ICF you will get the idea. the idea being these could replace the foam insulation.

[@pollyjetix2027]

Aircrete is NOT stronger than regular concrete. This has been proven conclusively by engineers. In fact, aircrete is extremely weak and will crumble under pressure.

[@1voluntaryist]

Aircrete is not made with aggregate, only water+cement= slurry, then mix in stiff foam, 1-1, and pour. Or add more foam if it's too stiff a mix. Loose foam is bad. Too runny is bad. Your foaming agent is probably not adequate. Or your gun is adjusted incorrectly, e.g., too much air. Are you sure it's built correctly? A good foaming agent is Suave shampoo for oily hair.

[@realazliving]

Dude, that black pipe is not pvc it’s abs. Yeah it’s a few cents cheaper, but unless you have transition glue, which you don’t, it won’t glue well to pvc. Also for pressure you should be using the primer then the glue, which I can see you didn’t (no purple drips).

[@jimbinger]

I was hoping that you would actually show how to build an aircrete machine especially since the title of the video is " How To Build A Simple Aircrete Machine". Just Saying.

[@sjr7822]

I've watch some demonstration, but, not everyone can do a good demonstration, I'm still looking for the perfect demonstration for a dummy like me

[@corax2012]

Haven't looked, but I wonder if there is better foaming agent than dish soap that may add strength. Foaming epoxy or something.

[@1voluntaryist]

"and creates a nice fluffy foam..."? No good. We want a heavy foam that lasts for a minimum of 2 hours. Remember, the foam keeps the expanded slurry mix from collapsing until it cures enough to be stable with maximum air pockets.

[@amandabruney3835]

I forget the channel, but a couple made aircrete by first mixing concrete normally then adding the foam. They made an entire backyard patio with their aircrete method

[@johnwolf1475]

Honey do carpenter.. who invented what this guy is selling... except his actually works

[@FrnnkEducation]

use dehydrated hay (old grass) for reinforcement. it will act like a natural biofiber reinforcement like helix double stranded zinc coated steel micro rebar but better because it will never rust on you and provides strength throughout the brick.aftewards you coat it in a sheet of concrete using a thing mesh

[@charllessmith6557]

It can also grow mold use ai resistant fibers for concrete

[@joshpoole6056]

You were using fast setting concrete, says so right on the bag jeeze

[@2112426gh]

use coarser Stainless or Copper cleaning pads, no rust

[@fiveforachange7997]

Copper would also work well! I didn't realize it when I got it but I definitely needed to get stainless steel pads!

[@alexandrunistoroiu452]

Hi, can you please do a tiny experiment for me? (since you already have the "foam machine")..., so, can you tell me what happens if you put the foam (just the foam, without concrete) in the freezer to minus degrees temperature? I want to know if it freezes, if it gets hard, solid....thank you

[@1976ClassicCelica]

For one Quickcrete is a name brand. I think you mean don't use readi mix. For another things it looks like you used fast set which sets in like 20 minutes. Try using type 10 portland mix. Lots of mixing time. Good video though.

[@sonofagun3193]

Your test cannot bei reproduced. That makes it void. You could experiment with adding sodium silikate to your soap/water solution i.e. to your foam. The sodium silicate will excellerate the hardening process of cement. This makes casting better controlable. Never add Aggregate to the mix but sand or another light weight filler.

[@ericmattinen4728]

You have the foam generator working, now just gotta work on the concrete mix. I would go with a 94 lb sack of cement to 6 gallons of water and then mix in 20-50 gallons of foam. Divide this down to a workable size. I would use either Suave shampoo or Drexel foaming agent. Dawn dish soap just doesn't hold up long enough. Suave is cheap and works better, Drexel seems expensive at $27 a gallon, but actually is cheaper when calculating cost per volume of foam. Check out Aircrete Harry here on YT. He even has some quasi-scientific testing of compressive strengths of bricks and some foam stability tests. Harry Rocks!!!

[@hafsalinda]

Research surface bonding concrete. Its used to waterproof a stacked construction brick box to create a swimming pool. No mortar needed its reinforced with glass and becomes waterproof after drying.

[@buckaroobonzai2909]

Would a super soaker or a bubble brush for car work? Maybe one of those spraynozzle bottle attachement things for garden hoses to spread fertilizer or insecticide with, but with soapy water instead.

[@MegaBobtube]

The purpose of the steel wool placed inside the tube is to make thousands of tiny bubbles and not to include it in your desired aircrete. I can't believe you included it as part of the aircrete.

[@fiveforachange7997]

How are you supposed to figure things out if you don't actually just try different things? I don't have a manual and this was my first time ever trying it...

[@joshmauk6791]

Looks great boss man but just 1 thing wrong. The purple stuff is primer and pipe dope and pipe tape is for threaded parts. But it looks awesome bro

[@necrokittie2291]

too much air flow for the amount of solution, probably not enough foaming agent considering it's about to get diluted with cement. wrong cement. never mentioned that wand is a pipe bomb that can injure someone if they glue the cap on. steel wool isn't a great option for inside the gun. i'd suggest aquarium floss batting or if you can find upholstery batting floss, both could fill the tube front to back and not get block the nozzle. just make sure you get the type that doesn't squish down when wet like pillow stuffing. a fully filled gun barrel would make foam with smaller bubbles and better carrying capacity for the cement because of increased surface area. if you increased the flow of bubble solution you could probably keep up with the air flow and make foam really fast.

[@balloney2175]

retitle please... say "DIY Foam Maker - Experimentation'

[@mwol287]

It sounded professional until Concrete was added. It should have been cement, not concrete.

[@federicomachon8841]

Thanks for the video May be you complicated things a bit

[@MervB1]

Couldn't we use a paint spraygun, possibly with a modifed nozzel?

[@anomikak1062]

great idea. or atleast i can see what valves are used in a spray gun if not use it as is.

[@MrLgmurphysr]

You should study up on concrete basics and perhaps talk to standard concrete pros. The steel wool was nothing more than a contaminate. It will never reinforce the concrete.

[@tonitouchberry894]

Uhhhhh! Honey! The steel wool is used to create the foam! Then the foam is added to a Portland slurry! Then the mixture is poured into forms. The forms can contain a reinforcement material like wire screen, which makes it a light weight ferro cement! Also basalt and other normal concrete reinforcers! BUT - you don't use steel wool to do that job!

[@josephdupont]

I want to make a pipe out of this stuff for rocket stove

[@emmacampbell982]

Thanks this is a bit easier to follow, nice to see the positive comments too, thank you blindorize. I have been told that sodium lignosulphonate is a good additive but not that easy to get unless you are a commercial buyer.

[@fiveforachange7997]

That's interesting that they would say that as Sodium lignosulfonate (lignosulfonic acid, sodium salt) is used in the food industry as a de-foaming agent for paper production and in adhesives for items that come in contact with food. Wonder if it does something with the foam instead of de-foaming it...

[@Snimbudio]

Thanks for the video! Going to make mine soon! A question and an idea: Do you use Portland cement or concrete (with aggregate)? My idea for a design improvement (please tell me what you think): What if the lower chamber with the nozzle were instead strapped on TOP of the other pipe, and then it would be sorta like a more portable rifle-looking thing. Additionally, to address the issue of awkwardness during filling, you could redesign the fill tube so instead of going straight up it would elbow over to one side before going upward. This would make the fill tube overall shorter and also provide a sorta kickstand to keep the thing upright while it's sitting on the ground. (I wish I could attach a drawing, but I hope you can visualize this).

[@fiveforachange7997]

I would suggest using Portland Cement as it gives you the ability to add what ever strengthener you like. (Sand, rebar, etc...) The elbow idea is a good one as it would definitely help with holding it up if you're going to have it one the ground. I can picture that working. And that then would work well with your idea of the "gun" part being on top vs. the bottom. The thing about this design is the clear hoses (in this case), get a little squirrelly as you try to move it around. Mainly because they have the memory of being coiled up and when you try to move the gun part...it tries to take the whole thing with it. That's why I just mounted it to a piece of plywood, so I wouldn't have to fight it trying to move all over the place. Good ideas and I would love to see your design when your done!

[@apauln]

Putting a LAYER of steel wool actually made a weak point. All that did was make a steel wool sandwich. It would need to be incorporated into the mix to be a good reinforcement fiber. Concrete needs to be in contact with itself all around the steel for the steel to be of any use.

[@Weslag1]

That is the dryest aircrete I've ever seen. Most people mix it so thin that it flows like water and they have to waterproof the molds to keep it from leaking out.

[@fiveforachange7997]

Yeah, I was just experimenting...that's the first time I had made it and learned a lot...

[@manor1730]

Could you use aircrete to make a countertop? Could you just do a skim coat of cement on the top and sides after it's cured to get rid of air holes? Would you add rebar to it?

[@tonitouchberry894]

Dawn dish soap is NOT the best!!! Try - "SUAVE" - shampoo! It makes a better foam and does not break down like Dawn foam does!!

[@NTF-zb9wi]

I haven't read all of the comments; so, someone else may already have mentioned these suggestions; but, just in case they haven't: 1) Use stainless steel scrubbies, NOT steel wool. 2) Swipe Honey Do Carpenter's idea of putting 3 links of stainless chain in between the scrubbies and the nozzle. 3) On the nozzle end, glue a male adapter onto the pipe; then, pur the nozzle into the end of a female threaded cap. That way, it's secure; but, you can still get into it, if you ever need to.... I did really like your idea of mounting it onto a board.

[@wesbaumguardner8829]

Use stainless steel wool so it won't rust. Why not mount the soap reservoir below the gun so you don't need the valve? Do you need the gravity feed? I would think the air pressure would be enough to force the soap water through.

[@johnswartz7872]

A “screw on cap”could be used , at the front of the gun.. and then it doesn’t blast off -at an unexpected time..And Can be used to open ,and close... the end of the gun , And if you use stainless steel scrubber pads ?...they don’t rust...

[@willdeburr]

Did you use a superplasticizer ? it seems that you didn't your mix was too dry .... and how many days did you wait for it so set (hydrate) you should have waited at least 2 weeks up to 28 days and then test the strength .... Cheers

[@jamest.5001]

The steel wool is just creating a void, making it weaker, the concrete needs to completely surround the reinforcement, the wool is too small and densely packed to be reinforcement. Try coat hanger wire, or something similar, even small rope, but the wire is better.

[@elizabethcool2241]

I havent seen a full video yet. And I look for it. There no how to build it step by step. Plz make one

[@Nowayjose-vd1wm]

What are the advantages of Air Crete over Concrete? Is it less expwnsive, lighter, easier to build with? What are the typical applications?

[@fiveforachange7997]

The foam adds volume and makes the aircrete lighter and yes, easier to build with. People have built homes and a multitude of other things with it.

[@patrickeh696]

It is FAR weaker Not Inclined. It is useful for facade and the like.

[@ronmtz4622]

It has insulation properties.

[@josephdupont]

have you tried stainless steel wool

[@tuppybrill4915]

Another video the person puts two steel rods at right angles across the exit end of the foamer to hold the stainless steel wool back from the exit hole. Another comment below makes the good point that if you glue the ends of the foamer on the foamer becomes a ‘pipe bomb ‘ if the hole blocks and pressure builds.

[@anomikak1062]

Anyone have issues with the air backing up into the soap container? Looking at some sort of one way or solenoid valve because whatever design i use it ends up bubbling backwards. I've tried the air spliter like this one and i tried using a pump for the soap.

[@simonlang2001]

both valves are removable, the push to fit ones if you push the small ring close to the tube into the body of the valve while you pull the tube, allows the tube to be released. some times a device helps pliers with a hole close to the size of the tube helps push the ring in.

[@dass1333]

Steel wool is bad you are probably looking for a stainless steel pot scrubber.

[@Brian-gx7yx]

I have a new idea, what about air crete for fence posts, Probably not good but if it works, it's cheap and easy

[@DrLove911]

Lol this is more complicated than most foam guns 😂🤣🤣😂😅

[@ZockyPocky]

Fan from the first vid!

[@brucemarmy8500]

Bless you for being so honest

[@linuxman0]

Great video. This gave me an idea of making an air foamer like this for washing an automobile. You just put car wash soap in it and spray down your vehicle, let it sit for a couple of minutes, then rinse it off. I'm definitely going to try this but will have to put a trigger valve that you squeeze and also a way to regulate the flow of soap so that it only pulls soap when air is flowing. I'm thinking that a venturi tube would do that but I'll see what I can use for that.

[@ThomSimone1]

Anyone interested, you can get it pretty close to what the Darwin suggested ($30). I bought the PVC pipe, nylon tee and pipe primer/glue from Lowes ($13.10), the fittings and and barbs from Walmart ($10.71) and 2 each of the 3/8" and 1/4" quick connect valves on Amazon ($13,58). Instead of the tap/die, step bit and 1-1/2" caps, my connection set included 1-1/2" FPT Reducing bushings, 1/2" to 3/8" and to 1/4" barbs. Due to the extra connection on the wand, I used an extra 1-1/2" tee and an extra 1-1/2" FPT. Not as pretty as yours :^) but no cost for the tap/die or step bit and still came in at just about $35. No drilling necessary. I already have the tubing from my brewery, so yes, I did manage to get by without that cost ($5?). The reason for the 2 each on the quick connects is that I couldn't find them as cheap buying them quantity 1. After watching another vid, I also decided that the 2nd 3/8" valve (along with the 1/4" one) would be installed right near the wand end (zip tied) allowing me to fine tune the air/liquid mixture at the end.

[@ngreat4390]

Too much grammar. Just two hoses and a pvc pipe and some foam will do it

[@ram1brn]

you are supposed to use stainless steel pot scrubbers not "steel wool " it will rust instantly one could also use plastic pot scrubbers as well

[@johntingle455]

This video is a perfect example of what not to do.

[@everettumphrey]

Very Nice! Thank you Sir! Could you add rocks into the pail or Fibers like fiberglass to help strengthen the mix as you make the Air Crete? I'm new to this so not sure what one can use to the mix on the receiving end. I know you can use molds with wire mesh and rebar, so was thinking fiberglass.

[@Poppacap79]

Why tap holes instead of using a reducer?

[@douglaspohl1827]

Set-screws really do their job of holding a cap on the tube... even in pvc! If you cannot control the mix of cement and foam formula along with working time... you end up with a mess...you say TWO YEARS of invention use? Your video did NOT provide enough useful DIY information. Thanks for trying.... maybe try another HOWTO video when you figure out how to be consistent.

[@firstlast-qo8pv]

A good DIY guy can look at sketch and figure out what to do. And other ways to do it. For example on my "cannister" I used threaded PVC fittings on either end for ease of clean out.

[@CC-jy4gr]

[@mikedewitt5880]

[@angeldeluz1398]

do you conect it to an air compresor???

[@MrAllan9]

Only use stainless steel wool.

[@jonathanpope5068]

Nice gun I wish your masonry skills and terms were a little better and exact. Quickcrete is a brand like sacrete or portland they make all different types of mixes mortar, cement, concrete, stucco. Are you using a cement mix which is 2:1 sand portland or what. Also Im assuming you do not want to use a fast setting product or is it better it drys while air bubbles are escaping.

[@fiveforachange7997]

Yeah, not a good idea to use a fast setting cement...As I've seen in a lot of the videos for it...it looks like also my mixes were to dry... And I was more or less experimenting with just a mixture. This was my first time, so wasn't going to be exact on everything as I like to know what not to do first so I can do better next time.

[@balloney2175]

please make another video showing the precise measurements of mixture/ingredients, timing, etc and the strength of the result

[@jershaus]

Get yourself some red scrub pads for the floor polishing machines. You need to cut them down but they will last forever.

[@jershaus]

You can add fiberglass strands or similar too. They make a lot of different stranding to add for strength.

[@siopaoman37]

Awesome!!!

[@ASHOKKDUBEY]

Great video. I have a portable double cylinder heavy duty car Tyre inflator compressor ( 150 psi/ 220 W/ 60 L Min. Flow) Can it be used to produce Aircrete . Pl. advice'.

[@dass1333]

A tire inflation pump would be to small. To make the thick foam you will need a lot of volume at 90 psi. If your pump can do that then yes it will work. A air tank can be used to hold the needed volume, it may take a while for a tire inflator. Hope this helps.

[@giannagiavelli5098]

i'm wondering if instead of steel wool maybe use those plastic bio balls ?

[@fiveforachange7997]

That's a great idea!

[@jonathanpope5068]

Also fibergalss is added to cement products for tensile strength and a binder you should not need it for small block where compressive strength is ideal or the block is worthless you are trying to break it with your hands. get a cinder block, foam block, and piece of fur and beat the crap out of it with hammer see results. Steel wool is a terrible additive it will rust and does not have longevity of steel rods or steel mesh that are used in construction these rods take decades to rust away.

[@fiveforachange7997]

Yeah, steel wool was definitely a bad choice lol

[@chrispeterson1195]

Lol lol lol lol steel wool wow

[@ravenrock67]

I've seen chains put in between steel wool and nozzle to try to eliminate blockage. Also, I've never seen fine steel wool used, always course. I'm also told Portland cement is what to use, but sometimes I wonder if that's all you can use. That being said, this was an awesome video. A very good job.

[@fiveforachange7997]

Yeah, I did end up adding the chains...which I had originally but just in the back, instead of the front...lol And you need to use stainless steel wool and not steel wool...it will rust and get clogged in the tube... Also, Portland Cement is what I recommend as it doesn't have all that extra in it and it's way easier to mix!

[@lancerudy9934]

Primer

[@whyte_lotis]

Have you tryed laundry soap

[@laserfalcon]

Interesting

[@wbmusarra]

When you mix the Portland cement, you may want to check out the plasticizers to the dry mix and then with the "recommended" amount of water(kzbin.info/www/bejne/f3TTZZyVmJWof9k). These will take a, what looks like dry slurry of cement and make it very wet. Has to do with the binding of water in the cement. You need to also look at the binding/reinforceing agents out there as well(kzbin.info/www/bejne/sIPIoZuOaL-jmJo).Some good information and videos out there for reference. Just do a search in the Utube library. Try the stainless steel scrubbing pads in the tube also. Good build video BTW.

[@fiveforachange7997]

Thank you! And I didn't think about the stainless steel pads...the ones I have now rust! lol

[@brentonlandolfo5527]

Hey Bill, im a Bricklayer from Aus. On occasions we use a liquid plasticiser in our mortar mixture (20mL) to help with the application and laying procedures (transferring mortar from our trowels to the brick corse that’s been previously laid) it is generally used with a ‘gritty’ sand (aka a dead sand, low clay content) The plasticiser will also reduce the speed in which the mortar will set, therefore allowing more time to roll joint the beds and perps which surround the brick (the finished product) As a side note... if we run out of plasticiser we will use household detergent. They both seem to have the same effect. Yes it does work in the sense to make the mortar more malleable, but what I’ve found is that after the mortar has been set for a period of time (30 days) the hardened mortar is significantly altered (broken down).. The mortar mix with plasticiser is easily removed by gliding your finger over the beds and perp joints (you could literally sit there and remove the mortar surrounding the brick with just your finger.. maybe a bricklayers fingers :) As a cured AirCrete is already a very powdered like material, I would imagine the plasticiser to increase the break down and not being an effective alternative. I am in the process of building a foam generator, I aim to test different types of ‘external membranes, additives, apoxies, reinforcements’ With what I’ve seen so far regarding AirCrete I would personally not include any steel reinforcement as AirCrete can absorb 3 to 4 times its weight in water.

[@Freedom1man]

Why, why, why do people keep calling ABS pipe, PVC pipe? www.diffen.com/difference/ABS_vs_PVC

[@fiveforachange7997]

I used a combination of ABS and PVC because that's what I had randomly lying around. Didn't think to have to differentiate between the two because really you can use whatever... Plus most people in general know PVC, so was just trying to keep it simple...

[@Freedom1man]

Five For A Change They are different and used for different applications. You also have to use a cross purpose cement to bond them to each other. I have mixed both in projects capitalizing on their different properties in different parts of an apparatus. I just prefer accuracy when instructions are given and parts explained.

[@fiveforachange7997]

I do get what you're saying but since it's just a simple little project I didn't get to detailed about it but will try to make sure next time to be more specific if I use PVC or ABS....

[@lemonbalm2604]

but did you catch what he said about the STAINLESS STEEL SCRUB>? that is a huge dfiference and no rust no tiny parts of steel wool. i really enjoyed the way you laid out the parts and labels etc. awesome

[@fiveforachange7997]

Yeah, that was another error I did...I didn't realize it when I got them but I bought the non-stainless steel kind which ended up just rusting completely together in a big gross lump...

[@dikkiedik53]

I like your channel very much. I live in The Netherlands and here also the aircrete is used, mostly as insulating material for floors etc. My neighbours got a floor made with it. They used oxblood as a foam medium, like the firebrigade for making foam to put out oil fires. Have a look at www.celbeton.nl maybe they have an English language page too.

[@fiveforachange7997]

I'll have to check it out! Thanks for the info!

[@deonjackson4005]

how much steel wool do you need in the gun and I am just getting air true the front of the gun but if I put my finger on the front to stop the air and let go I will get a little foam can you tell me what is wrong , the gun was made just like the one in your video

[@fiveforachange7997]

I should of used stainless steel wool instead of just steel wool. Also, I usually pack it tight enough to be able to create pressure. You might not be using enough to create that pressure.

[@deonjackson4005]

I used 2 stainless steel wool in and 1 regular steel wool cut the gun size down but the front keep fly off when I put air on

Well, this was just an experiment...the stuff I made wasn't very good. When you get the mix right...it's actually really strong.

aircrete is never strong compared to normal concrete. MAYBE ~1,000 psi. Thinshell concrete easily goes to 8,000. So again WHAT IS THE POINT in making something so weak?
