Papercrete Battery Dome

[justfly2525]

Awesome job! Thanks for all the great info. I like the idea of pumping papercrete but I wonder about the thermal bridging of the double armature frame of the dome? Does all of that metal transmit hot/cold through the rebar truss system and into the interior of the dome? I'm sure it works for a battery dome but if you built a house would you eliminate the thermal bridging somehow? Keep making these awesome videos!

[BrokenRRT]

Another great video.. Can you please tell me where you got the plans for the iron frame to make your dome. It looked like rebar but hard to tell in video. Thanks!

I adore the creativity in this product. Keep up the good work.

[datzfast]

could you spray that trailer house also? moulding in some really fancy art nouveau architecture ?

[stazistazi]

love the videos and bishop allen doesnt hurt either ha

[AdmiralBoom76]

Too much concrete. You could make the same kind of structure from a mixture of subsoil, sand, straw and a lath frame.

[sklarm]

This material is appropriate to my area. We don't have straw or subsoil as we live on landfill in the southwest.

Also...We don't use any concrete only a small amount of cement.

[MrNeosoul99]

You are so awesome! I want to do this here in Manitoba, Canada! :-)

Just observing these things as they are going up in dry climates. As to Northern NY where something like this could be built, but in a wet climate can become problematic. For instance, lets say the the inside is not filled correctly or atleast pumped with low-tensile strength concrete. The inner structure, considering it is light gauge steel will start to rust.

My only conclusion if this was built in a wet climate the structure would permeate a lot of water. Needs a foam outer shell.

Thanks, sounds like some really interesting material.

Hi Mikey, you rule, nice vid.

BTW it might confuse us Mexicano-related fools less if you made it clear that you are not using prickly pears AKA tunas AKA the fruit of the cactus; but rather IF I figured it out right you are using Nopales, the laves of the aformentioned caactus.

So that ingredient can be called nopales rather than the paddles of prickly pear.

Is that what you are using, the paddles?

[sklarm]

I'm using the paddles, not the nopales or tunas.

[oldbearswitch]

Gracias Senor,

Gracias! Now I have seen at the very end of the video you are using the big paddles.

im looking up every method into making my own eco home in the middle of australia, this one is one of my favorites? whats the insulation value of the house?

[sklarm]

Roughly R=3 per inch or R=36 for the whole thing.

[sklarm]

paper is a wood derived product that behave much like wood. It needs to be sealed. I used a elastomeric roofing seal for the final indoor and outdoor coats. It will need to be reapplied every 3-5 years.

Using paper for building is quite similar to the concept of strawbale. Both of these light weight fibes are very insulative giving you a home that can go without heating or cooling.

[oares00]

this is not very clear, it shows nothing really.

[sklarm]

What would you like to know/see? We have dozens of videos on papercrete.

[oares00]

Thanks, it'll be nice to see the real work in action. But I'll go to your site to learn more.

[tomterahedrob]

why paper?doesnt it rot?would a fibergass-cement or ferrocement be alot more durable?

[IsraeliTerrorism]

Lovin It!......Keep The papercrete videos coming!.

[IsraeliTerrorism]

love it!

How water resistant is the prickly pear paint?

[sklarm]

I'd say that our prickly pear paint is not looking particularly water resistant, although we have been using relatively small amounts of prickly pear in recent batches. Still more exploring to do on this.

[dyssolve]

I read somewhere that the prickly pear needs to be "fermented". Whatever that means...

Great video, very informative!

[jaydedman]

having this documented evidence of a successful papercrete project is invaluable. you do a great job explaining the different pieces to the project.

[sklarm]

If I recall correctly rabbit weed and milk thistle can also be used to make materials like paint or glue. Do some research for this words and see what you can come up with.

[Mortarsprayer]

Great video Mikey!

It is so neat to see all of your progress.

To keep up to a sprayer, the compressor should be rated for at least 7 cfm at 90 psi. For an electric compressor that is usually a 5 hp 220 volt machine. For a gas compressor, slightly more hp will be needed.

Keep up your good work. The sharing you are doing with video is helping lots of people see that they can build homes for themselves.

Best regards,

Nolan

[sklarm]

I think I said the compressor horse power was 9 in the video and it is probably more like 6. I've been shooting at 90psi and enjoying that level of pressure for my light weight fiber heavy mix. I can get about five full shots of mortar sprayed before the compressor kicks on to refill the tank.

[Mortarsprayer]

The cactus juice sounds like a big hit for you. Do you have other suggestions for us less fortunate people without that as a resource?

Thanks again for sharing so many videos. Your enthusiasm is addictive.

Have a great day,

Nolan
