- Explore the role concrete plays in global warming and how scientists are working to create a cleaner, more sustainable concrete.
--
Today roads, sidewalks, bridges, and skyscrapers are made of a material called concrete. There’s three tons of it for every person on Earth. It’s also played a surprisingly large role in rising global temperatures over the last century. So, what exactly makes concrete problematic, and what can we do to fix it? Explore how scientists are working to create a cleaner, more sustainable concrete.

The soundtrack was indeed an essential tool for the filmmakers to let me know how exactly I should be feeling.

Why is it always like this SAME here tooo😭😂😂😭
@@Brightifyisthebest why
@@Brightifyisthebest why put the advertisement du lusche self promoting
@@Brightifyisthebest thanks for wasting 10 seconds of my day
Got this as an ad. Finally, ads tailored to what I’m actually going to enjoy.
All my chem nerds out there know that for every MOLE of cement produced its one MOLE of carbon dioxide and since the molar mass of calcium oxide is greater than the molar mass of carbon dioxide, its closer to 0.78 tons of CO2 per ton of CaO produced. Nevertheless, this is still a great video! Keep up the good work TED-Ed!
You're right, and if you take the whole process of making cement into account it changes little. Making one mole of Brownmillerite (4CaO·Al2O3·Fe2O3), plus the CO2 produced from heating the kiln and transport it adds up to quite similar amounts per unit of weight. I typed it all out under a different video, I'll try to find it.
found it: Calcination of limestone yields 44% CO2 and 56% CaO by weight. If we go to the final mineral, 4CaO·Al2O3·Fe2O3, we get 1 4CaO·Al2O3·Fe2O3 (MW: 485.96) + 4 CO2 (MW: 176,04). Then CO2 is (176,04/(176,04+485,96)=) 26.6% of mass produced. If that CO2 release gets doubled from kiln heating+transport, that's ~42%.
From this video btw: ruclips.net/video/UmnFTffYM3w/видео.html
As soon as they made this mistake: I scrolled down into the comments to see if there is a comment like this, nice.^^
@@Tinky1rs still that bit in the video is misleading and many may try to apply it in a different situation and fail the test😂
@@kcravuri It is sloppy, yeah. Basic stochiometry.
Perhaps whoever gave the information has ton as a unit of quantity in their language too. Dutch uses "ton" for 100.000 (usually currency), as well as for 1000kg.
Agreed!!! I was weirded out when I heard it because the masses of CaO and CO2 are not equal!!!

😢😢😢😢 I don’t like homework. I am a moron 😢
I saw a video on the cement problem recently and I remember how surprised I was to find out that concrete has a big impact on our climate. I think that's a topic a lot of people don't know about. Thank you for educating :)
Ahmed Khan, India: a scrap dealer, came up with a method to convert the ever-increasing piles of polythene into Polyblend, a cementing material which can be used to produce higher quality roads.

Imagination isn't a material
@@Brightifyisthebest dude stop
I used to work for a concrete testing laboratory, and the toughest sample of concrete we ever received was some old Roman concrete. If I recall correctly, the most likely reason was that they built without reinforcement, and anything that wasn't tough as old boots has collapsed in the last couple of millenia, so we've only got the best of the best still standing.
It’s a good day when Ted Ed posts
Well for me it's good night lmao
"We are the first generation to face climate change and we can also be the last generation to face it" .
If we can beat the greed out of the human race LOL ain't going to happen
that second statement could mean we may either fix it so no one has to or there will be no one left to fix it.
Why do people quote a man that bombed a hospital? It's frustrating to see people look up to these types of people
@@josiahlutchman4913 Obama did not bomb a hospital. I doubt he owns any bombs. The U.S. military did what you say without his approval. They have bombs. The airstrike was requested by Afghan forces who had come under Taliban fire. Obama apologized for the U.S. military's role in the error. The Afghan forces carry more responsibility though.
@@josiahlutchman4913 If you're talking about the Kunduz hospital in Afghanistan, then you're misleading. The U.S. commander in Afghanistan, John F. Campbell, said at the time that the strike was made in the U.S. chain of command, but never elaborated whether or not Obama was directly part of the chain or was aware of it's authorization at the time. You make it sound like he directly ordered an attack on civilians, when in reality Campbell and Afghan forces likely had ordered the attack on the assumption that Taliban forces were nearby. The blame can be more squarely pointed at Afghan commanders and U.S. commanders who weighed the idea that civilian casualties were a necessary sacrifice if it killed Taliban forces.
Can we take a moment to appreciate the INSANELY GOOD animation!

Not only them but you must also know about the Indus Valley Civilization from North West India, because they were the most intelligent civilization in the History of the world I think, they used Interlocking bricks and also knew about most of the things we use today, like Bath Tubs but those days they were huge, and they even had great economy in their civilization and a good knowledge in science as of those days

Im in the construction business and from personal experience I've seen cheaper and cheaper materials being used. This video is very informative but we are building very cheap. The building we work on are mostly office buildings but we do work residential too. These buildings are built to last decades and im talking less than 40 years those buildings will be better off reconstructing than remodeling. We need to build to last, the romans built with some strongass concrete. We need to build to last centuries. Also work on a type of building which can be easily remodeled or parts that can be easily replaced. There is tons of waste of good material too in the way we build.
Love the way the boiling frog keeps recurring in this series. King Kong Frog at 0:48!

The title is likely gonna change...
The title is complete click bait. This is solely climate narrative bs with a very brief history on cement. Nothing to do with the title at all except some vague conjecture. Also it's moronic, they are complaining and demonizing one of the most essential life giving elements on the planet CO2 which is a byproduct of cement production. While ignoring there won't even be much cement production because of the lack of river sand. Which I'm sure TED has covered already. It's completely disingenuous editing and hijacking a whole video doing a bait and switch to push a narrative.
The assertion on insentives in production and manufacturing for carbon capture is absolutly true, this is one of youre greatest videos yet, more comparisons between ancient and modern would be amazing
Hi TED-Ed! Great video, I enjoyed it a lot as always., including the message of the video. But there is a mistake at 3:07 where it is said that a ton of CO2 is produced per CaO. Since the molecular weight of CaO is 56 g/mol and the molecular weight of CO2 is 44 g/mol, the ratio would actually be an approximate 786 kg of CO2 per ton of CaO. Maybe the ratio was concluded counting other manufacturing factors, but if it was determined by chemistry alone, then I think it is wrong.
Does anyone besides me, want this world to be borderless?
Until there are viable altenrative solutions for steel, concrete, chemical, glass, and agricultural industries, net zero will be nearly impossible to achieve. We've done the easy part: energy and transportation. Now, the public eye needs to shift towards focusing on emissions from industry.
Net zero will always be impossible
@@josiahlutchman4913 Not exactly impossible, but very hard to achieve.
And to think most buildings are made of concrete and steel. We must not put the cart before the horse. There is still of lot innovation, science and engineering to be done before we can even think about net zero.
As long as there are billions of us, we have a problem.
Ted-ed videos have become, a way of entertainment. The presentation is marvellous; the designers have the ability to present gruesome facts with precise beauty. Bravo
That's the correct way to show something that's bad, giving a headline to solutions so instead of making us afraid we become proactive
Can we talk about the soundtrack for a second? It's amazing
Governments should intervene to provide the economic incentive for carbon capture technology.
Why? CO2 destroying the planet is bs. It's only being peddled to steal money on a wide scale for a "carbon tax" that does nothing.
@@WaterspoutsOfTheDeep Do you have any evidence that carbon dioxide does not cause climate change, please?
@@billyfox6368 Yes a study published showed during the pandemic the earth heated up because there was less CO2 and other emissions making the sky more clear and more sunlight reaching the earth. Water vapor is the major greenhouse gas not CO2. Climate is much closer tied to solar output. You're welcome.
@@WaterspoutsOfTheDeep Please will you get me a source for that?
I remember crashing onto the concrete with my bike. It was at that point I wondered why it was there.
Also a company figured out how to make concrete without C02, many companies have taken it on but it's an expensive process.

"for every ton of concrete theirs a ton of co2"
Umm that's wrong so I'm gonna correct that so its for every mol of CaO made from CaCO3 their a mol of CO2 released. I mean how are you gonna get 2 tons from 1 ton of CaCO3, bro this is supposed to inform the public so how about a little error checking next time. Other than that good job.
3:08
@@nicholassaez4405 Was searching for this comment. Thank you 🙏
It says for every ton of concrete there is a ton of c02. Which means they've already used two tons of limestone. There is no mistake.
"I mean how are you gonna get 2 tons from 1 ton of CaCO3" - They didn't say that, they said for every ton of CaO you'll get a ton of CO2.
You're right about the incorrect unit though, they should've used a mole as opposed to a mass unit. But then you'd have to explain the concept of the mole to a bunch of people who have little/no chemistry knowledge.
Given the molecular weights are pretty similar (44 & 56 for CO2 & CaO respectively). It's still a pretty hefty amount of CO2 produced, around 0.8 tons of CO2 per ton of CaO if my math is right, so the point still stands IMO. Though maybe they should've just went with a statement like that instead of focussing on the equal amount (in molecules) of CaO & CO2 being produced..
@@valorific I think they were trying to get across that you get equal amounts (in quantity, not mass) of CaO & CO2. Due to their molecular weights being a bit different, you'll get different masses of CaO & CO2 out.

I love the wide variety of topics all TED sections are covering. The quality of your content and how it is done is great, always interesting. In this episode, I was wondering though how you come to one ton of CO2 for every ton of cement. The calculation behind it is not transparent for me. Is it the "heating/ burning" of limestone plus the CO2 out of the chemical reaction. Only the latter would make less than half a ton. I am just curious.
