- Timborako, on 09/03/2008, -1/+5This is going to be huge for two reasons:
1. "Green" cement is great PR for construction companies. If the article is correct and cement manufacturing accounts for 5% of CO2 emissions, global warming activists will be creaming their pants.
2. It is cheaper than regular cement by $10 a ton, which pushes this technology away from pipe-dream and more towards reality.
Now of course this technology will take lots of time and money to get going efficiently and on a large national/worldwide scale. Very cool though and so simple! - inactive, on 09/03/2008, -0/+4It eats lots of fried chicken and grape drink?

- Nateon, on 09/03/2008, -1/+4I can see this taking off. It's cheaper than regular cement and when it comes down to it, the people buying are going to go for the thing that's the most cost effective.
- sndream, on 09/03/2008, -0/+3FYI, Nuclear plant plant don't emit CO2.
- phrawgh, on 09/03/2008, -0/+3Uhhhhhhhhhhhhhhhhhh, no and no.
- mta3d, on 09/03/2008, -0/+2cement is the leading human cause of carbon dioxide production so this is the biggest single step humans can take :)
- dizzy113, on 09/03/2008, -0/+2No, just reminded me of some fat kid I saw at metro zoo wearing a shirt that was pink and said "pink is the new black"
- mecharabbit, on 09/03/2008, -1/+3So the waste heat from existing power plants can help make cement? Sounds like a winning proposition to me.
- inactive, on 09/04/2008, -0/+1Green Cement - seems all good - but I am wondering why there was nothing said about the properties of the end product - Concrete. Concrete quality and properties are determined by chemical reactions and the proportions of the materials used. I would like to know more about the final product and whether any of the basic properties of the concrete changes using this new cement.
- bbfishfinder, on 09/03/2008, -0/+1I'd have to agree with that one.......no different than walmart selling organic products.
- hardwarehank, on 09/03/2008, -0/+1When I see an electric cement truck, I'll believe you.
This is just another industry hopping on the bandwagon. - BrandonDiggs, on 09/03/2008, -2/+3
they should dye all the cement green - stev31h, on 09/05/2008, -0/+1dude, wtf?
- QubitTarutaru, on 09/03/2008, -3/+3Strength and durability is a very important factor in cement. Structures need to have a special, sometimes unique, mixture to hold up to shear and compression stresses. I would think that this would play a major role on how much this method can be utilized.
Don't be blinded by the term "green" alone. I hope this can be an effective alternative. - palehorse864, on 09/03/2008, -1/+1...
Btw, this is not a criticism of nuclear power or anything. Just a gag on the word green, and the idea of something glowing nuclear green. - inactive, on 09/03/2008, -1/+1This encourages traditional power plants. It reduces their effects, but to me, is just a quick fix. Which is good, but not great.
- ryanwarnersteel, on 09/03/2008, -3/+2More proof that we have the solutions, its the system in which they are created that causes the catch-22. Capitalism drives the innovation needed to discover this technology, but the ability to produce the cement can't be revealed due to patenting so that money can be made off of it, keeping it from immediate, widespread use. Endless treadmill of production.
- Bennzor, on 09/03/2008, -1/+0it sounds like a farce to me, green cement? Timborako was right; its just PR.
- phrawgh, on 09/03/2008, -2/+1I never understood what the big deal was about (insert subject of thread), its completely over rated and full of (insert pseudo intellectual psychobabble on the nature of whats wrong with the media). I mean seriously, anyone who likes that (see 1st insert) should go (insert insult of the moment/insulting meme).
- inactive, on 09/03/2008, -3/+1Don't get me wrong, I think this is cool. However, my dad is involved in the construction of two cement plants right now each costing over a billion dollars. It would be really difficult to raise the capitol to build green cement plants given the necessary upfront costs. Hint, compare the cement industry to the auto industry.
- palehorse864, on 09/03/2008, -4/+2And if the power plant blows up or irradiates things. It's still green, just a different kind.
- inactive, on 09/03/2008, -4/+1It sounds like a good idea in theory but I'm little skeptical that they might be in cahoots with the power companies
- inactive, on 09/03/2008, -6/+2Anybody else read this as "green semen" and get mysteriously hungry?
