What is Foam Concrete?

Foam concrete is a lightweight concrete that is made with dense foam, or suds added to a concrete slurry mix (cement and water). The dense foam is the aggregate in this mixture instead of sand or gravel for example. Foam concrete is mainly used for its insulation properties.
There are a number of foaming agents that can be used to make foam concrete, or aircrete as is is also known. The number one foaming agent is Drexel FM-160. This is a high quality professional product that is more expensive than some other options for foaming agents. If you are making a large amount or a high-quality project, you may want to make the investment into this Drexel product. Otherwise, you could make aircrete using concentrated liquid dish soap or even shaving cream. These products can make a dense foam that can support the weight of the curing concrete, at least for a time.
Vegetable glycerin is added to the concrete mixture when making foam concrete to prolong the lifespan of the bubbles. This allows the concrete enough time to begin the actuation and hardening process before all of the bubbles collapse under the weight of the wet concrete mix. When the bubbles do pop or deteriorate inside the hardened concrete, there is a tiny void or air pocket left behind which helps improve the insulation values of this type of lightweight concrete mix design.

What an excellent idea to use this Product for a Better Result! Excellent Video. Thanks for the info !

[GrumpyAndCricket]

I have been wanting to try this out for a while, Good info thanks. Have a fun day!

Heard of aircrete before but not of putting the glycerine in to make the foam last longer. Makes perfect sense though, thanks for the tip!

Good video and no annoying loud music!

Hello! I am very happy to find your channel. I have sone question, I want to create concrete flower pots, small, medium, and large sizes. Do u recommend this technique? Can I also add acrylic or latex paint to the mixture? I am guessing there is no need for sand if I am using foam. Thank you!

Idea: what do you thing about creating a wall around the yard using aircrete? My idea is to put a board barrier on each side of the existing chain link fence, then pouring the aircrete in there. This should provide extra righty and structural strength for the wall.

"if you want to see those videos you will have to subscribe to the channel." I am subscribed and thoroughly empathize with the hairy details and time-consumption of video post-production. Can you tell us _which_ videos show foam crete being employed? A search for "foam" renders six results, five of which are how to make fake rocks out of styrofoam.

Great info, thanks! Have you had a go at making aircrete yourself Steve?

Hey Hi I really like your video. But I have a question that I am not too sure on the answer so I do any keeping I am in California I was looking for AAC blocks but I cannot find them in my area will this type of concrete work for building a ant farm block?
Thanks

so what's the formula, and what is the yield vs the same amount of cement with normal concrete, has no one demonstrated the same amount of materials, and then show the volume difference

[azimihossen]

should i use vegetable glycerin when i use drexel fm-160?

[mariaqtiturrino]

How much cement you use? Can you please write the recipe Thank you

[dgavin]

Im interested in purchasing those pots up above. Do you have a website where I could purchase those?

[casade]

THANK YOU! 👏Could you add foam to "regular" concrete with aggregates (not just portland cement) to make it more flowable or insulative? I do not mean aircrete only but "normal" concrete, i.e., a bag from one of the big stores? Thank you all!

[thesheeptradewallstreetliv]

I need your help please, what is the Cement foam mix ingredients, to make super super super strong and very very very cheap, for filling a mold 40*41 cm, 4 cm deep.

Please i need your good help coz this is my last hope projct after losing job

[marcoglara]

This is a very disappointing video. There was actually no foam concrete in this video at all.

Why didn’t you make some and show how it works?
