Not sure what the lime does but I think it helps stabilize the bubbles, Honey Do Carpenter talks about it, haven't got a hold of any J-lube yet. Oh and the Quick Set 20 I used 2 parts Portland to 1 part Quick Set, but I only used it in a test batch I made.

Burton, Thank you for watching. My mix is basically 16 to 1 Portland cement to hydrated lime and a tablespoon of baking soda per 16 lbs of cement. I will do another video on the Quick Set 20 mix I did when it cures a bit more.It seems to have not had any collapse, it has cracked but I did move it soon after so I think that was my fault. I bought some Drexel foaming agent for about $24 a gallon including shipping and tax and I think that will probably be the ticket to good no slump aircrete. I hope that helps feel free to ask questions, I'm no expert but I'll tell you what works or does'nt for me.
  Bitchute sounds interesting, I'll check it out. I appreciate your offer to help, I'm pretty illiterate when it comes to anything technological but getting a bit better since I started youtube. Thanks and have a great day.

Here is my finished through the wall flue for my rocket mass heater. I will probably be using a barrel stove until I get the floor done but I will need heat to do that. Also experimenting with aircrete to prevent slumping? collapsing before it sets up.

Thanks for watching.

Orin Raichart I'm not sure of the weight or the R value but I do know the R value is fairly significant. I have seen guys put a propane torch to it for several minutes, like 10 to 15 minutes on 2 or 3 in. peace and still not feel the heat. I do not have an accurate way to measure other than bathroom scales and measuring cup an I like to keep things quick and simple. The main thing I'm concerned with when I make my sub floor with aircrete, other than being structural enough to hold the weight of a 1 or 2 inch hard concrete floor is to have enough insulation to give a good thermal break from the earth below. It would also use a little less Portland than a solid concrete floor and then with solid concrete you would have to put insulation under for a thermal break. How toxic is it to make that blue foam, plus I figure it is at least half the cost of The blue foam.I may even consider trying a cob floor on top of the aircrete subfloor.

 R Scott, interesting concept, cob-foam or aircob. I may try some experiments with that. maybe even add a small amount of cement to help stabilize it, or plaster of paris or hydrocal. Crap here I go spending more money on experimentation.

 Thanks for watching guys.

This is what I am doing to go through the wall with my flue. I will probably use black single wall inside and insulated pipe outside. This setup will be for a wood stove temporarily to heat a large sun room until I can build an aircrete sub-floor with a hard finish on top. Then I can build a rocket mass heater. I will run the wood stove full throttle and stack concrete blocks and sand to hold heat to help prevent creosote.
 Any ideas or comments are welcome.

The one problem I now see is the amount of cure time for aircrete, it takes about 2 days for it to get hard enough to even touch without making a dent, but I have a lot of research before I actually try this, Papercrete would be more solid but I think aircrete would have more  insulation value. Aircrete Harry, if you are familiar with him, has what he calls an epic mix that has styrofoam beads and paper in it but not sure of the exact mix he uses. He also puts baking soda in aircrete  to make it harder so I want to try that.Thank you all, Any input is welcome.

Hey Burton, sorry I was at the other homestead for a few days so I had no contact with the civilized world, lol, no cell service unless I go uphill about a half a mile.
It does stay dry and dusty so I really see no need for plastic and I really need to research and experiment with it to get the right mixture. I was watching Aircrete Harry and he used baking soda in the mix and ended up with a really hard mix. What I have made so far takes a couple of days to set up enough to where you will not crush it if I touch it very lightly. I may also try an excellerant.
I'm doing a 20 x 40 ft. area but 10 sq. ft. at a time. If you have any ideas or suggestions feel free to comment. I have a lot to learn about this stuff and what I have done shinks about 5 to 10 percent, I think using Drexel may help with that. I think I need to watch more Honey Do Carpenter and Aircrete Harry.

I am planning  on putting in an aircrete sub floor because I think it would be at least 1/2 the cost of blue foam. I'm a believer in insulating floors, cold feet, no good. Then I want to put about 2 inches of earthen floor on that. It is a large room 20 ft. x 40 ft. and will be a sort of sun room 2 sliding doors and 6 windows so when the sun hits in the floor it should store a lot of heat. I'm doing 10 ft. squares at a time.
  I think this is a fairly economical way to build a floor, carpet may be cheap but they also off gas things as well as the plastic underneath that you do not want in your body. Even though Portland cement may not be the best for our environment, I think is a lot better than Styrofoam.  
Here is a video I made of my aircrete foam generator. It's a new toy so I'll be make a lot of things with it I hope.


Thanks for watching and God bless.

Well I finally got around to making my foam generator so now I can finally make some aircrete. I plan to make an insulated sub floor for like 1/2 the price of blue foam and then cover with 1 or 2 inches of harder concrete or maybe an earthen floor, that will act as a heat sink when the sun shins on it. I plan to make a few aircrete videos so make sure you subscribe so you won't miss out and thanks for watching.

This is a pond I built about 7 years ago I think, I was very resourceful and not counting my tractor, fuel or my time I spent about $600 dollars building it. It is on the highest part of the property so there is no runoff  but I have a 30 x 72 ft. high tunnel that has no problem filling it from the runoff. The pond is 32 x 52 ft. and 11 ft. deep. I lined it with old chain link fence and chicken wire with 2 in. cement. Its got plants on the sides and drain tile under the gravel that the plants are planted in and a pump to circulate the water. It works really well but I am building an earth bermed pond below to circulate  water from to keep the cement pond at a constant level.
I hope maybe this will help give you a few ideas, good luck.
