A trio of students at Binghamton have apparently found a way to make concrete from crushed glass. This has been possible for a long time but their breakthrough was in finding a way to use contaminated recycled glass. It's obviously better for the environment, but it's also stronger and cheaper than regular concrete, so they claim.

My whole life has crashed
Won't you pick the pieces up
'Cause it feels just like I'm driving on broken glass
Driving on, Driving on broken glass
Driving on, Driving on broken glass

Interesting to hear about glass concrete it reminds me of plastic bottles to turn into concrete too.

Cement made from glass, not concrete.  Cause they've been using glass as aggregate in concrete for a long time.

Interesting concept. I'm not sure their concrete would be any better for the environment than standard concrete. It may be at the front end, but it's not clear if it also gives off less CO2 than lime/clay-based cement currently used. Concrete is responsible for 8% of the total CO2 added annually, about 3.4% in production and the rest estimates from curing concrete. Hoover Dam and other large older dams are made of concrete still curing internally. I'd like to see more.

Thanks for posting.

Something between very wishful thinking and outright fake news.
At the very least their "patent pending" claim is dubious - I couldn't find any USPTO application by either company or names. Could be a legal issue for them.
confusing cement replacement with pozzolanic material is another significant issue.

I remember hearing a similar idea where plastic could be asphalt or cement too. But it's a wait and see process for now.

I hope they make cement tires because all that glass will do a number on tires when it gets worn and there are potholes.

Researchers at Worcester Polytechnic in Massachusetts have found that by adding an enzyme found in human blood they can make concrete that will heal any cracks automatically within 24 hours. The enzyme reacts with carbon dioxide in the air to form calcium carbonate.

They say that this would increase the cost of concrete by a small amount while quadrupling its durability. This is a big deal for highway and bridge engineering. And it's a reminder that plenty of innovation in Massachusetts can come from outside 495.

while interesting, i don't know if i can put much faith in a website of supposedly innovative ideas that banishes capital letters and seems to promote its monthly readership and article shares above anything else.

Lots of people say they like cold winters. But if we analyze things closely we see that the consensus among humans is that cold is bad, and even among plants and animals there is that same consensus.

When we ignore someone, we are "giving them the cold shoulder"
When two countries have poor relations, we describe those relations as "frosty"
When we say someone has a "cold personality" or is "cold hearted", we don't mean it positively
House Stark urged vigilance among its members by saying "Winter is coming"

This is not a coincidence, people have shown a clear preference for warm weather in surveys and in their migration patterns.

And plants and animals agree. In winter, not summer, trees shed their leaves and animals hibernate or migrate south. The Amazon Rainforest is teeming with biodiversity while Siberia is a barren wasteland.

I took a class (Design of Reinforced Concrete Structures, fittingly) with the professor leading this research effort my junior year! Funny guy, he once broke rank with the standard academic stance and went on a rant for half of lecture about how *great* Wikipedia is :-D
"Now, what if da Bearss were to enter the Indianapolis 5-hunnert?"
"How would they compete?"
"Let's say they rode together in a big buss."
"Is Ditka driving?"
"Of course!"
"Then I like da Bear buss."
"DA BEARSSS BUSSSS"

Two can play.

When one is angry, they are said to be "hot".
When one takes a gamble and loses, they got "burned".
When someone is in increasing trouble, they "have the heat turned up on them".

When there is anger between parties, people seek to "cool the situation".

Given how much CO2 is pumped into the atmosphere making concrete, I wonder how much can be removed with this process. As the phys.org link shows, 8% is due to that. Between not needing to replace stuff as frequently and what little CO2 can be sequestered within the healing process, any bit helps.

This site was much more informative.

In 2018, researchers at the University of Maryland discovered that, by boiling wood in Sodium Hydroxide and Sodium Sulfite and then putting it in a hot press, they could make wood as strong as steel at one sixth the weight and at a cost only slightly higher than regular wood.

They've created a company called Inventwood to commercialize it.

We might one day be driving on wooden flyover ramps and bridges!

Unlikely, the concept of growth in the logging industry is not likely to happen due to environmental interests.

You clearly live under a rock. Timber is now in fashion as an environmentally sustainable alternative to concrete and steel. Have you not heard of Mass Timber?

I mean, it's a Kernals12 thread.  Isn't only looking surface deep into a topic and only seeing aspects that support his view just kind of how he rolls?
