New ' green ' concrete's on the way,,,
 
http://www.durabilityanddesign.com/news/?fuseaction=view&id=9525&nl_versionid=2995

wasn't bad enough the ethanol joke has destroyed the corn food market,,, now some ***hole will present the notion ' IF we can do this w/the world's largest building material, we need more resources to feed the method ! ' it becomes an ever-increasing circle of shark mouths to feed :eek:


i, for 1, long for the return to days of panty raids, keg parties, & other assort'd meanderings :thumbup:

Just another in a long line of admixes that won't show the actual real-world short comings until we've poured a few hundred thousand yards out that fails. But thankfully, tearing-out short-lived concrete and replacing it doesn't add to any carbon foot print...........:whistling2:

We already use slag and flyash, which are recycled materials. What more do you people want from us?!

It sounds like "cute" and interesting concept that has been over worked and conceptualized for years.

Someday, the U.S. will catch up with Europe in the practical use of natural resources and practical construction.

i dunno, dick,,, icf's still haven't grabb'd up a significant portion of the bix & that's been avail for over 50 yrs,,, we did, at least, adopt eifs albeit it took a few yrs & lawsuits before we realized how they shouldda been employed,,, expect we'll see soybeans next :laughing:

Make All Government vehicles run on Natural gas. we have over 100 years of developed Natural gas and over 1,000 years of undeveloped natural gas reserves. and what is so cool about that is where there is gas there is oil too! There natural gas 50% less green house gas emissions. better then any bio fuel not cutting in to our food supply.

Not to go off topic, but have you seen the car that some guy built that runs off of natural gas? It's called the Magnolia Special.

Well since you quoted me I feel I should respond.

While I agree that ethanol is not a viable solution to, well, anything, your post is just a big fat exaggeration trying to make a point. The actual facts about ethanol show it is unsustainable, you don't have to make s*** up.

Most estimates show it takes a gallon of diesel / gas to product 1.3 gallons of ethanol, maybe even worse than that, but NOWHERE NEAR 8 gallons of diesel to 1 gallon of ethanol. NOWHERE NEAR IT.

Also the idea that ethanol production "cuts into our food supply" is absurd. They're not taking corn from grocery stores to produce ethanol. It's being grown for that reason.

Again, I don't like ethanol, but the actual facts make it pretty easy to dislike it without gross exaggerations. The problem with making up "facts" to support your opinions is that no one believes you when they do their own research, so you end up just hurting your cause in the long run.

This thread wasn't ABOUT ethanol though, it was about some green concrete stuff that uses LEFTOVERS from already produced products. And that may be as much of a failure as ethanol is, but at least someone's trying something. Lots of things in the "green" movement are a scam and stupid, but staying the status quo where we depend on a bunch of insane countries in the middle east for 90% of our energy seems a hell of a lot stupider. I appreciate people TRYING things even if they fail.

My first issue with US Ethanol is that the growth of the raw material is not competitive. If ethanol is what we want as a fuel source, we could buy the raw material MUCH cheaper than what we pay in subsidies to grow non-edible corn in this country. We could then plant prime Midwestern acreage with edible food crops and subsidize them if we must! Right now, and of course not just for ethanol, 87 percent of corn grown in this country is inedible without heavy carbon footprint post processing (please and it matters not the ratio of diesel to ethanol) ---into corn syrup. Again, we could buy other, healthier, sources of sugar than corn cheaper than subsidies to corn farmers.

And corn farmers, sadly, are no longer the little guys trying to keep a family farm of generations going. They are corporate divisions or employees now.

Most of those just a bit younger than me have never eaten a US beef product fed with its natural diet. Really! We feed inedible corn and its roughage to animals we eat to the point even though they are not genetically built to digest it. We are not built to digest the crap properly either and just look at us as a result these days!!!! Processed corn syrup is the sugar component in just about everything we eat. When I was younger their was still cane and beet sugar in things. Not saying it was great in high doses either of course but look at the obesity graphs as corn syrup took over completely. Very hard to ignore what they show.

We compensate with mass doses of antibiotics given to the livestock industry to the point 67 percent of all antibiotics sold in this country is now to agriculture. We eat it and we wonder why we become antibiotic resistant to the most simple strains of infections. I remind you "Superman" died not of injuries from his tragic horse riding accident but from antibiotic resistant bed sores.

We over nitrogenate inedible corn crops so that the phrase "Knee High by the Fourth of July" means tall as two men by April. It does not rhyme but the run-off down the rivers is destroying aquaculture in the Gulf of Mexico.

And then, we hear that a University in the grain belt is suggesting we use corn roughage in concrete? Surprises me not at all. What better way to continue the ruse. And just wait for elected officials from the cornbelt to mandate its use in concrete.

Oh well. Just spent an hour pulling a power washer engine apart for a friend who really needed it working. I replaced all the rubber parts and bought him a couple quart cans of non-ethanol fuel to get through until he can get to the marina for fuel without that crap in it. Somebody on this site posted that a friend of his with a small engine business has added $20K a year in business thanks to ethanol. So I guess it is great for the economy.

And SDSESTER, you have not even touched on the genetic modifcations we've made to our food chain in the name of production, both to plant crops and livestock.

Yes, but thanks to them we can drown non-edible crops, that need post processing to eat, in RoundUp and increase crop yields of GMO plants 10 fold per acre. The extra waste can go into concrete as we learned from the OP.

We are going to get our subsidy money back! Yippee. Pour me a RoundUp on the rocks! There is enough in my system now that it will not create offspring too terribly birth defected.

Remember when was Dow was relabeling Agent Orange and dumping it on Northern California, Oregon and Washington forests and orchards as a safe hervicide after the Vietnam War? Birth defects 1 in a 1,000 were written off as coincidence even though they occurred 1 in 10M or something before the use of the stuff.

Meanwhile, foreign countries will not buy GMO grain and other crops so do we a) tell farmers to quit growing it in favor of something edible and marketable, or b) increase their subsidies to keep growing it and then come up with hair brained ideas for getting rid of it? Like mixing it into concrete.

Remember when we oversubsidized the dairy industry beyond market forces and had warehouses full of cheese we could not get rid of? Why does any ideation for getting rid of leftover, over-subsidized, overplanted and over harvested unsaleable corn surprise us?
