Concrete is the most widely used construction material in the world. It can be found in swathes of city pavements, bridges that span vast rivers and the tallest skyscrapers on earth. But it does have a weakness: it’s prone to catastrophic cracking that has immense financial and environmental impact. What if we could avoid that problem? Congrui Jin explores how to create a more resilient concrete.

This new 3d animation is stunning. Great work as always Ted Ed!!!
Aadiv Rath Ik right
Damn this animation is so good
probably done with blender
I was suppose to say that
I wish it had the apt thumbnail :)
The concrete is adorable.
It's better than I can do
Thumbs up for the animator 😀👍

What a rocky start
We will heal all the mothers backs

@@spicyPoke Thanks for showing me this
This man
lmao
My mom is sending you a thank you for the suggestion.
Then we wouldn’t need the myth of stepping on a sidewalk crack...
kremit the frog XD love that joke
Exactly, we dont need crack, crack needs us to exist
..Or sacrificing Chicken's and (based from urban legends) children's blood on a bridge.
@@BM-su7kc what?
@@ClownDollThatHasContemptForYou in my country, people often sacrifices chicken by lacerating it's neck and letting it's blood drip on the pillars. Same thing on sacrificing children.
Edit: it's neck that they are lacerating.
The rocky boi looks so adorable
Darkness Dash I like his hair
@@bobafett1105 i agree on that
He is my spirit animal
The editing of this video is amazing.
As civil engineering student, this looks amazing!
About the cracks, when they appear on a Beam it means that whether the steel or concrete are not well design to bear the stresses. Therefore, when the cracking appears it could meen that the structure may fail (and not necessary because of the concrete that colaborates in the compresion zone, it may fail in tension) and we must avoid a britle failure (very rapid cracking) so people may be allowed the evacuate the builidng. I would like to know if this self healing system can avoid this kind of failure in structural elements.
Oh yeah, physical problems too. But I wonder, do the healing cracks put more strain (or stress, I really don't know) on the entire structure?
“For bridges and roads that are constantly in use”
Coronavirus: LETS CLEAN THAT UP
No.
You don't want to see, but to those who are curious enough, not everybody can afford luxury of staying at home at most times. And not everybody is willing to cooperate, since, at least, you know, unlike America & Europe the rest the world can't afford to fight windmills, such as climate change and intolerance towards minorities, we have real problems to deal with.
I wonder if this idea is a work in progress or if it’s already concrete...
I’ll see my way out.
Booo
Get out
Use duct tape
smash them haters
Awesome
Lovely 3 D animations TED.
This is something new on TED.
I can only imagine the amount of work needed to create this.
Please make a video on the process of wood formation...
The animation on this one is exquisite, just like all of your content. Thanks, TED ED.
TedEd: What if cracks in concrete could fix themselves
Me: What if concrete would never crack
Exactly. Maybe if they were slightly elastic and they would produce very small bends instead of small cracks.
@@mrflip-flop3198 I believe the cracking is because the elasticity of concrete reduces over time.
The issue is that concrete has a very high pH inside, but when the pH lowers over time the concrete becomes more and more unstable, and the good thing with the bacteria that precipitate calcite using the so called active pathway is that they also increase the concrete's pH. The downside to that is that at some point it may become so alkaline that not even the alkaliphilic bacteria can survive.
Every single time, a new yet flawless style of animation...
Ahaha low poly animation. Saves a ton of render time and still looks good. Also, as a civil engineer, this video was very satisfying to watch. 😊
yeah what a great time to do this recommendation
only if florida's apartment builder could see this sooner
I bet you when this becomes a thing some people are gonna be like “NO! THIS CONCRETE IS DANGEROUS WITH ALL THOSE SPORES, I WON’T LET THE GOVERNMENT DO THIS TO OUR INFRASTRUCTURES”
Damn Karen....
Star Trek: Uses spores to travel instantly around the Galaxy.
Real life: The government wants to put spores in us!
I could totally see a Karen pulling this. “It’s my constitutional right to not allow spores into my house”.
Well then we give them rock treatment I guess. All jokes aside, the video doesn't state when the micro organisms die and if they're immortal is just about the only important question the presenter doesn't have in this video
@@noocrat1234 If it is repairing the concretre with existing material, if it increased the lifetime of concreate by 10 times, it is still a success. I agree that they could drop some resources to read on
That is buy far the happiest chunk of reinforced concrete I have ever seen in my life ❤️
Well *The War of The Worlds* would have ended pretty quickly with those little dudes (or giant tripods?) just...stuck...
👾
No one for Tom Cruise to safe. That be horrible
Tom Cruise needs his daily dose of saving people!
Watching this after what happened in Florida. I knew some of this yet I just wanted to get a gist of its properties.
Everything this video shows & explains is fascinating! It's short, understandable, & interesting yet educational. I find it easier to learn & remember when hearing & seeing the info. More videos like this one, please!
"sounds like just a theory?"
"yeah, we don't have any concrete ideas."
This animation is just WOW, kept my attention for the whole video!
Top notch quality, content and knowledge! Great job👍
The content in the video and the way it was presented never stops amazing me.
This is a really interesting concept! I have some cracks in my house, and I think it would be quite fascinating to see these cracks heal themselves.
This really helped with my stem class thanks a lot!! :))
Im loving the animation! Really smooth and well done!!
The bacteria names used here fully detailed in the paper, google " *Methods to improve microstructural properties of recycled concrete aggregate: A critical review* " , in google and you'll find all the information of how to do it..+.+.+
Anyone who does the animation work at Ted-Ed deserves a big raise
I was paying so much attention that I didn't notice the 3-d animation used, knew about it after looking at coments. But now I know why this video is why different from the old ones, happy evolution :)
“ *more than a few tons* “ LOL
This technology is the first step towards giving concrete its consciousness.
Flex tape?
*I sawed this concrete in half*
Solves all problems!
@@aduck5011 That's a lot of damage
That doesn't solve anything
In the future cracks in concrete will be able to repair themselves using stem cells.
and and AUTONOMOUS AI WITH BLOCKCHAIN
Nah
You’re joking right?
In the dark apocalypse, we have started building shelters out of starving babies.
MIND NOVA He is talking about how in the future concrete buildings will be able to fix itself by using the brain that all concrete is born with do you think he is joking? I mean concrete with brains is a very serious topic.
I was mind blown by the fungi solution, Makes me want to become a material scientist
Then you'll be fun guy.
The animation in this video was excellent!! Good job!!
This is mind-boggling
This is amazing. 1mm is just enough to make it practical.
Superb animation once again, good job ted animators
I love your lil concrete guy
as someone who just started working in the construction industry, i reaaally enjoyed this video ^-^
Ted's animation has got better.
Wow...
but is it a health risk? If someone touches it, can they wash it off? Will it form kelloids when it repairs itself? Is it cheap? So many questions.
i dont think is cheap, neither i think the spores are a health risks to people unless consumed in X cuantities, in the correct cuantitie of usage shouldnt form kelloids. Yet, i know nothing, this are only my ideas and thougths about it.
My favorite part is how the concrete's hair is rebar :D
Yeah, I liked that too. 😁
The government of Canada, especially Quebec, should invest in this technique
I always find TED’s animations adorable and the lessons shared interesting.
This brings a whole new meaning to 'problems won't solve themselves'
Concrete has a life span of only 20 - 30 years?? But most buildings stay standing for more than 100 years without any renovations? I have seen people even sell their properties which are over 30 years old? Can someone explain?
Unreinforced concrete can last milleniums if done properly. Reinforced concrete on the other hand, rarely lasts more than 100 years as the steel ends up rusting inside, greatly reducing the strength of the structure.
I think it's Concrete alone, not including the other stuff like the Steel Cables inside of it or something.
I'm pretty sure the video was referring mostly to concrete on it's own with the 20-30 year life span, not reinforced concrete. With reinforced concrete, some cracks in it doesn't mean it's completely nonstructural, until the rebar rusts it still holds a significant amount of strength and structural support, it's just that if you see cracks you should probably repair before a larger problem (the rusting) occurs. Concrete has really bad tensile strength, but really good compressive strength (in fact most if not all stone has bad tensile strength, this is why arches were so useful, as they direct the stresses down the sides so that everything is under compression and not under tension). Because of this you usually won't see concrete floors or etc on buildings that use non-reinforced concrete. Concrete on it's own, like Antoine said can last a very long time, just not often in structural situations, regular concrete can easily be used for small walls or other structures that only rely on concrete's compressive strength, such as walkways/sidewalks (not bridges, that's reinforced), small walls, etc. Regular concrete is only used in situations that don't rely on the structural support of the steel bar that gives reinforced concrete its name. Thus water getting in its cracks isn't as big a deal, and even with cracks, since non-reinforced concrete is used almost exclusively in situations where tensile strength doesn't matter and only needs compressive strength, the concrete can still support itself and any weight on top of it, however it is then still quite vulnerable to many scenarios that could cause a major failure, and if part of it fails, then other parts of the structure start having to deal with some tensile forces. However if maintained well any concrete structure can last a long time, and with reinforce concrete especially if you live in an area with low humidity or rainfall, and a temperature that stays mostly consistent throughout the year and doesn't go through major swings in temperature, then the concrete can last far longer as well.
Paragraphs please, spare my eyes.
More limestone plaster mixed in
that little concrete block is so cute! These are entertaining, TED-Ed!
The animation is outstanding, and the topic is incredibly interesting. Great video.
The cement animation is soooooo cuteeeeee :DD
Yeeeeaa
What a great animation .Impressed😍😍
0:30 Hes either crying or cracking at the eye.
thanks for all great-free stuff..
The animation is so good
Day by day I am getting infatuated withour your content and especially animations😍🤩
As a civil engineering student, this video makes me happy
*I love TED-ed.*
This is some serious innovation.
every time i open this channel i found something unique :))....thanks ted-ed......hit like for ted-ed
Loved the animation
Wonderful animation
Brilliant, informative and fun - thanks for sharing!
1:53 bro who hired those builders
Thanks for the video.
Someone: quiet, spores are sleeping
Me: *LA!LA!LA!LA!LA!LA!LA!LA!*
Great illustration. Easy to understand
I never thought about self healing concrete......thx for new thought
Why does ancient Roman concrete seem to last so long without spalling? I have seen several ancient concrete structures, which have experienced around 2,000 years of weathering, show little to no cracking. I have often wondered what made their concrete better than modern material. Is it as simple as the composition of the volcanic ash?
the animator has sense of cuteness
twos nature is our best supporter of innovations
I love the combinations of different animation styles :D
*That’s a lot of damage!*
The sidewalk outside my building has been torn up twice (maybe a third time) because of cracks forming. It's wasteful. Love to see this stuff poured on instead! 👏👏👏
these animations are freaking awesome!
Please make a video about road construction
Wow! Love the new animation style 👍
Great animation guys! As usual.
This graphic is so amazing.
I don't know why people in the comment section can't differentiate rocks and concrete.
The pyramid of giza (stone)
Greek architecture (stone)
And those are definitely not cement.
good idea, two thumbs up
Wow a new animation style i like it
1:46 crack detecting a crack
A few years ago, I started playing a video game that spoke of strange technologies that employed microorganisms to repair metal structures between immense storms, without the need for any sapient construction workers. How that technology was described sounds an awful lot like these spore mechanics in concrete discussed in this video. We're living in the science-fiction world now!
Awesome and informative video
WOW
Great animation
Pro animation blend with world-class education makes 'Tedx'.😇
Interesting topic; great narration.
Please upload the history of umbrella and this animation is very good
that was super interesting & the animation was great
Amazing animation. 5 stars out of 5.
Amazing, This concept is something we can make a project report on but tilting (our project head) will not get it.
I want more animations like this!!
Do a next video in fast travel ways or the cheapest way to create roads
(If they exist)
Interesting topic. But how about the strength of healed concrete? Is it going to be fully restored to the initial condition?
Well, that be great.
No more potholes? Sounds pretty grand!
@@TommoCarroll How bad are your streets back home? (UK I presume.)
@@Brainstorm69 'bout as bad as biggie smalls, thug life mudthah fackurr
Love the animation
All I know is that my mother's childhood home; that had sprawling concrete, stands to this day.
Woah, this animation sucked me in. Ted-Ed is TH-cam’s fastest evolving channel. 👍🏽👏🏽👏🏽👏🏽 I love learning here.
So you're saying the animation sucks? 😉
