I thought we had figured out the romans formula for concrete.

We need a more modern, lightweight, and easy to handle material in which to make the next generation’s version of soviet style cinderblock housing for the masses.

I’d be happy if my driveway didn’t crack.

A. Take contents of 5 Michelle Obama’s Healthy Lunches,
B. Take copy of ObamaCare for Dummies, by J. Gruber (out of print) Send book through shredder to create a buoyant ballast.

C. Mix both Lunches and shredded paper with 1 pint of 100 degree, recently distilled water,
D. Put in Blender on Puree for 57 seconds.
E. Quickly pour contents into metal molds or receptacles.
F. Place in direct sun or under heat lamp for 8 hours to firm.
G. Enjoy your new bricks! (DO NOT EAT THESE BRICKS)

This article sounded like a lot of bs essentially saying, let’s look for better ingredients for concrete.

[Company Man]

Looks like an opening for nanotech.

You can take MIT courses on-line.

I am currently doing that and achieved a passing grade for a certificate due in some weeks. :)

[ErikJohnsky]

maybe we can just get cinder block and say it identifies as concrete!

[Jonty30]

Jus don’t use Obama’s promises as a binding agent, because that stuff doesn’t hold.

Not so obvious in the above text is that the warmiists want materials that are not processed using combustible fuels hat produce carbon dioxide. That is how all ceramics are made: bricks, glass, and pottery, and portland cement for concrete.

Durable materials are not made with low temperature processes economically. To think otherwise is rather ignorant. It is high temperature processes that has permitted complex civilization as we know it.

...reduce the carbon and energy footprint, and even enable us to sequester carbon dioxide as the material is made.

Doesn't sound like science to me. Sounds like Political Correctness searching for grant money.

“If we can replace cement, partially or totally, with some other materials that may be readily and amply available in nature, we can meet our objectives for sustainability,” Buyukozturk says.

So there is no problem with concrete as it currently exists and is currently made other than the supposed problem of it not fitting in with the sustainability requirement.

Just to be clear: if you fall on concrete hard enough, your bones break, not the concrete.

[urtax$@work]

now...??....... they are thinking about using nanotech stuff?

i guess we are living at a snails pace , fast !

[Dr. Bogus Pachysandra]

“with the structure and properties of natural materials such as bones”

Made by Yoyodyne?

[Dr. Bogus Pachysandra]

Wow! “Buyukozturk” is my middle name!

[TXnMA]

Volcanic ash + cement?

Remember when cinder blocks were promoted as a great advance because of their lighter weight and superior strength?

[Harmless Teddy Bear]

Animal blood makes for a more durable concrete.

I now await the screams of horror.
