Atlas City Project

Carbon concrete
This recycles the carbon created by the manufacturing process back into the concrete, which also makes it more durable and lessens green house gasses.



This video thanks to our buddies at The New-Z Land project.

this is a really cool technology. i wonder how much it is price wise as it could make itself prevalent in Atlas City.

They made it seem that this is also a cheaper alternative then the possible fines and taxation for high carbon pollution, but it's only in Canada right now. Maybe this is something we could also start here to help finance the city. I know there is a lot of discussion of a financial network to pay for the cities since none of us know about grants (and no one seems to be working on them yet).

Ah, there it is. Thanks.

I would be interested to hear about any tests done on the structual effects of this, and also the durability of the product over time, eg. does it fail.

My preference is to us materials with a long history of reliability, and to be cautious of new products that are untested in the field.

By all means use new materials, but in a small number of buildings, so any unforseen failures that develop don't effect your entire community.

Most of these materials are not so much new as they are improved. They take decades of trial and error and mix it with newer design and technology.

I was just watching a special on domes and this material looks promising

ETFE
en.wikipedia.org/wiki/ETFE

They put this light weight, transparent, very durable material in dome projects in 3 layers. Each layer is inflated with air for very efficient insulation. We could use these on the south facing greenhouse walls the same way and it would likely be much better then the double or triple pane glass that would be needed otherwise.

Related to concrete, this looks promising instead of steel which is prone to corrosion:

So it's lighter, stronger, better tensile strength, no corrosion, same expansion as concrete... anything else?

Seems pretty useful

I hear its a little more expensive than steel (Though with steel constantly rising in price, this may not be the case forever..), and as yet I've seen no long term studies on its reliability, but offhand I'd say it looks promising.

In the UK at least, it has yet to receive legal permission to be used in buildings from what I understand. (Though they have built at least part of a bridge with it.)

Much like the issue that in the UK, you cannot use earthships for residental use, and the likelyhood of that happening is pretty remote anytime soon. (Being that the materials often used are seen as hazardious landfill materials, eg. tyres.)
