When you switch the foam generator on each time, you need to catch that first bit of not-foam and keep it out of your mix.

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.

Just joined, I love your videos and am learning so much! Hope you keep creating new backyard tech we can use and adapt!

Your passion for foamcrete is highly admirable. I used to use CaCl2 as an accelerator. For a firmer foam, you can slightly reduce the air pressure.👍

I absolutely love these videos. We need more like you who think green and frugal.

Thank you for your service

I enjoy your experiments with rocket stoves.

Those sound like Canterbury windchimes. Beautiful musical accompaniment for a Great video!

Thanks for sharing this experiment. Very interesting in the foaming agent that would be not Drexel and still be working well as Drexel can't be shipped overseas. So Palmolive 1:16 seems a good fit so far :)

Thank you for your ideas. We enjoy your channel

Thanks for your work ❤

🌬 Wind One of my personal fav's. (Good one!) 👍

man... I apreciate that you show your mistakes, so it's the most commons results we usually obtain.... and we get frustrated often... but it encourages me to continue trying and experience this material....

Just built a rocket stove from David S site. Was like your j stove. Like your content. Honey due video go long. Like u get to the point. A big thanks from Australia

Omg I loved my shout out. 😂🤣😂🤣😂🤣😂🤣

Excited for this video! 👏🏼👏🏼👏🏼

I like what i see,great job on know how of creet

Nice foam generator

Nice I want to learn this stuff too

Vaseline works well to seal and makes releasing the thread on cap easy .

One of the first things I ever learned about concrete is it's composition... Water, cement and some kind of aggregate... In this case, there isn't any aggregate... cement is a glue, and only becomes concrete when a bond is made between the glue (cement) and the aggregate such as rock, sand or even perlite. The foam just creates air bubbles that make the mix lighter, not stronger. you need another component to create the bond.

Presumably, if you sealed the crete forms, they wouldnt collapse because the air wouldnt have anywhere to go right? and for larger /stronger slabs, baybe what you should do is make a bunch of small aircrete tubes/bricks and break them up, then use the broken up crete bits, to make a new mix of crete, like a styrofoam crete but using small busted up bits of air crete instead of styrofoam

Os-da dough-hee-joo = Cherokee "Hello, how are you?"

"Hello" in the New England states is the middle finger. Works with "Good-bye" as well. LOL

Happy Saturday 😊

I used perlite to make lightweight concrete, while it costs more, so much less labor and tinkering involved. If you are not making a building, no reason to bother with foam to save $10.

cool

Use old motor oil to grease molds , its mixed with diesel and spray with garden sprayer. Quick and cheap. If cold weather use handful of calcium chloride to heat mixture, then pour.

The problem I see here is your air pressure. Its the reason your gun is spurting out the foam and not just creating steady flow and consistency. I would advise you dial down a little bit and observe how that turns out. Another thing you might want to check is that you're using a proteinaceous foam and not synthetics like SLS... SLS rise quickly but don't hold structure well over time...

Try getting some lightweight aggregate to include - pumice or expanded shale maybe? Whatever you choose you want something rough and jagged not smooth and rounded. Also what about playing with admixtures? You can buy air entertaining admixture online, maybe locally too but you'd have to check stores in your area. Last edit, I promise - I notice that the tops exposed to the air seem way more crumbly than the rest of the concrete. Concrete needs to stay wet to cure, and I'm wondering if the mixture is drying out too quickly. For the surface area there's going to be a lot less water in aircrete than normal concrete, so maybe it's drying out faster too? Look into "wet cure" and see about that for your future testing as well. Keep up the great videos.

if you add a touch of glycerine to the foam the bubbles will remain firmer.

on your reservoir cap cut an inner tube or other rubber and glue to the inside of the cap so that the edges will cover the male connection. That should solve your leak. You might be able to use a toilet bowl flapper seal but not sure if that is the right size. I get inner tubes from tire shops, they usually have bad ones laying around.

In Yorkshire we say "Ay up!" For hello 👍🏻

Have you considered making the fill tube longer? That way you can fill the carton from the bottom up.

Great, I am looking forward to these experiments. Your big block was perfect, Aircrete is always going to be able to be pressed in with your thumb, you can always render a stronger sand cement mixture on the outside of your finished project to strengthen it. I think your slurry was too thick, as you already know water is essential for the cement to chemically cure it looked too dry. Did you cover the aircrete in the forms to hold the moisture in? I like your style, how you wing it, but if you get a really good consistency you would need to know the ratios in order to repeat it

The foam always seems to start out bad and then get to shaving foam consistency but you catch the bad foam in your bucket. I think you should run it onto the ground until the foam gets good and only then direct it onto your cement. Actually the foam seemed good straight away for the mix at 30 mins but the earlier mixes had the issue.

Good video! Pro tip for though, your mix got too wet because your foam generator was putting out an initial foam that was mostly solution and very little air hence the having to add the portland to your aircrete to thicken it up, I try to have a bucket set aside for that to catch that first really wet foam so it doesn't mess up the consistency of my mix, also be careful with how many scrubbers you use because on these smaller diy generator's if you set the pressure too high and the scrubs clog at the end your solution tank could rupture and I'd hate for you to get hurt. A good example of that happened to that kid over at aircrete creations, he didn't get hurt but he hadn't glued the gun together yet.

Greetings.. excellent content you have build up here! I’ve seen many others about cellular concrete and this it’s by far one of the best since you’re making a binnacle of your own experience and testimony.. one of the thing I could see you’re doing different it’s that you’re using ordinary dishwashing soap.. and I’ve seen that and industrial component as pure propilenglicol or and industrial foaming agent it will end with better results! Another thing it will be the batches.. I can’t remember what you’re using but smaller batches of 1 or half a kilo of sand by 7 or 3,5 kilos of cement dust with about a liter of water plus the necessary quantity of foaming agent to that liter you will get with about a quantity slight less than 5 gallons and it will be better that try to mix large amounts of the aircrete! Probably because light machinery as a drill with a mortar mixer bit accesory will worked better to mix up the cellular concrete without deinflate the batch.. and heavy machinery will tend to overmix the aircrete! Another thing it’s that we tend to think that any kind of sand will work well but just regular sand or even fine sand will probably make a good aircrete.. but I’ve researching and a good quality fine sand or better than those a good river sand will make a difference not decanting on the bottom of the mix!

In my language we say "hello" it's english for "hello"

creative content.. looking forward to the results. Some thoughts: seemed like the dry cement used was lumpy/clumpy which will make it more difficult to achieve a homogeneous mix and effect strength. You want a very smooth portland cement slurry to start. I'm thinking the 1st batch that resulted in a very thick chocolate mouse like consistency will turn out the best. The gritty batches looked off. Aircrete is a simple yet very precise process. Not sure what your ratios are . You might have better luck achieving proper density trying suave clarifying shampoo, dawn or seventh generation dish detergent which have yielded successful results for other aircrete enthusiasts. Maybe consider doing a little larger batches and injecting the foam to the bottom of the bucket by adding a longer pvc piece to the end .... so it will incorporate better. Foam tends to want to float to the top. A fellow youtuber MAN ABOUT TOOLS did aircrete raised garden beds and shares his smaller batch recipe with precise ratios. The video is entitled: "Make Lightweight Concrete Garden Boxes PART 3 - Aircrete Vermiculite Lava Rock" kzfaq.info/get/bejne/msqVl7Ce2tCbqI0.html at about 10 in he demonstrates aircrete. it might help to replicate his recipe initially to get the correct ratios established. Best of luck in your aircrete adventures.

Remember curing takes around 28 day's for more strength. It will get stronger the longer it sit's. So try those thin samples again and try your test again and see if there is any change.

How do you know the container is full of foam? Looks like you trap a lot of air at the bottom.

eu uso algo muito melhor que espuma, e fica perfeito!!!

Good morning. :-)

You should work on a styrofoam grinder and mix very fine styrofoam with the aircrete.. for styroaircrete... also add some stronger cement mix to the top and bottom of the pour to give more surface strength without too much weight gain...

I love wind chimes and have some of my own but they are distracting on your video.

What is the air pressure set to?

Tu espuma esta buenísima pero hay que conocer las proporciones.

If your foam is collapsing so quickly, your foaming agent may be the problem. The commercial people use very fancy synthetics.

You should use a o ring the seal the resavor cap

a little late but put a regulator on your air coming in and put in only like 30psi and experiment a little might even do less. This will make it denser, your foam is too coarse, also I would do better screening the cement to powder or mixing better before the foam the big clumps and coarse foam are hurting your consistency in the finished product. also might try better foaming agent or some accelerator or baking soda to get the cement to cure faster before your foam collapses.

The ratio for cement should be 6 gallons of water for each 90lb bag of cement. Looks like your mixture is too stiff

Ola cómo estás, love from Ibiza Spain

G-day mate

Good'ay mate, from Oz.

Cheap vegetable oil works well on forms

I don´t remember, if you had a German welcome yet. If not it´s "Guten Tag", which would be pronounced "goot ´n turg" in English and means "Good day". Thanks a lot for your videos. I learned a lot and will be building my first oven myself, soon.

Thank you friend but idident know about afoam agent yet

no man is good

What is the sufficient foam density that i have to maintain , bro?

👍👍응원합니다 👍👍🇰🇷

Dzień dobry i dziękuję

Add glycerin to the liquid to help the bubbles survive longer. Also the reinforcement is too tight for such small form. Maybe 1x1 mesh...

Can I put salt on garden to get rid of the Ivy's in my garden

About 20 yrs ago, I remember houses being built with a mixture of concrete and recycled styrofoam filler which otherwise would be trash, made into bricks/ blocks. Structural. So why Aircrete instead? Just asking.

G'day mate

Dzień dobry from London :)

There seems to be a agricultural foam soap who holds forever

Kumusta in spanish sounds like Como Está? what means: How are you? that is used to say hello too. I think that is thxs to the Spanish Building Empire.. who arrives to Filipinas and start to devoloped the country. NICE!

Can you use the concrete beads from your failed attempts?

mabuti🙂

The scothch brite pads are good. For higher density increase the air pressure ...try 50psi.

Maybe it would be good filling icf block

try to mix a shaving cream with the cement

Waa Gwaan hello in Jamaican

Texas and we say howdy

We say “ fuck off brother “... only to good friends though .

I was thinking Air Crete is not ment to be structural it is to make concrete lighter. To use in between supports that hold it more solid. If you want to use it instead of blocks you will have to make them thicker. Put the wire inside but also put a layer of something on the outsides. Maybe a fake brick or a thin fire brick. It by itself is not stable.

Hola, yo estoy muy bien observando tus videos que son muy importantes para mi. Si entendiste lo que te escribí espero tu respuesta con un emoji de 😉 Saludos desde Colombia en el sur de América.

Doesn't soap weaken mortar? Hmm. Try gauging your mixes more accurately, use a smaller bucket and work out a ratio. Then adjust. Never going to get consistent results eyeballing it xD

how about an aircrete pizza oven???

In Australian: g'day.

Add glycerin to your mix

Dzień dobry ... :)

The watering of the blocks is important and is Where most of the stiffness comes from.

Yo/Whassup Dawg/Get him!

Osiyo the Cherokee greeting. And just to let you know the Cherokees do not say goodbye

There is no issue with concrete. Use concrete hardner for better result

1-Take down the wind chimes before filming, put them back up when done filming for the day. 2-Next start testing for air/limecrete (limecrete lasts thousands of years using volcanic ash as the filler instead of sand).

why not put latex in ?

I think if you want accurate results you need to have accurate amounts on your ingredients in order to find what is or is not working.

where is the sand?

Hello; здравейте This was my Grandpa's language.

You may need to add something to make your bricks sustainable sand ,fiber ,steal

Salut (don't pronounce the letter ‘t’) monsieur = Hi sir (Mr). You can pronounce something like (more or less) ‹silu masia› The French ‘u’ pronounce differently than in English but I have no clue to help you for that. Thank you and congratulations for your very good work and your pronunciation of the Japanese language

You should try and make the concrete with salt water.

Hello

Why dont you go to the $ Tree and buy their plastic containers for your form!

Namaste is Hello in Indian..

el grumo del cemento es porque esta vencido
