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.
Lesson by Congrui Jin, directed by Aeon Production.

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 😀👍
#dicksoutforaeonanimations
What a rocky start
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.
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.
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.
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
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!
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?
Lovely 3 D animations TED.
This is something new on TED.
I can only imagine the amount of work needed to create this.
The animation on this one is exquisite, just like all of your content. Thanks, TED ED.
“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.
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.
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!
Every single time, a new yet flawless style of animation...
Please make a video on the process of wood formation...
"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!
The content in the video and the way it was presented never stops amazing me.
yeah what a great time to do this recommendation
only if florida's apartment builder could see this sooner
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. 😊
Top notch quality, content and knowledge! Great job👍
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
The animation is outstanding, and the topic is incredibly interesting. Great video.
I always find TED’s animations adorable and the lessons shared interesting.
That is buy far the happiest chunk of reinforced concrete I have ever seen in my life ❤️
The animation in this video was excellent!! Good job!!
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..+.+.+
Brilliant, informative and fun - thanks for sharing!
Superb animation once again, good job ted animators
Watching this after what happened in Florida. I knew some of this yet I just wanted to get a gist of its properties.
Great animation guys! As usual.
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 :)
This really helped with my stem class thanks a lot!! :))
What a great animation .Impressed😍😍
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.
So useful! Thanks!
these animations are freaking awesome!
Thanks for the video.
as someone who just started working in the construction industry, i reaaally enjoyed this video ^-^
Anyone who does the animation work at Ted-Ed deserves a big raise
Day by day I am getting infatuated withour your content and especially animations😍🤩
that was super interesting & the animation was great
Interesting topic; great narration.
Wow! Love the new animation style 👍
This brings a whole new meaning to 'problems won't solve themselves'
thanks for all great-free stuff..
Wonderful animation
that little concrete block is so cute! These are entertaining, TED-Ed!
Loved the animation
This animation is amazing!
I love the combinations of different animation styles :D
This is mind-boggling
Awesome and informative video
I love you guys!!! Your videos make learning fun. ❤😀🤓
This is some serious innovation.
I was mind blown by the fungi solution, Makes me want to become a material scientist
Then you'll be fun guy.
Nice informative video
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! 👏👏👏
WOW
Great animation
I want more animations like this!!
Very interesting!
Love the animation
As a civil engineering student, this video makes me happy
Amazing animation. 5 stars out of 5.
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.
This graphic is so amazing.
love the animation
good idea, two thumbs up
The animation is so good
Amazing, This concept is something we can make a project report on but tilting (our project head) will not get it.
“ *more than a few tons* “ LOL
amazing animation 😎👍🏼
*I love TED-ed.*
This is so awsomeee. Great examples of biologic engeneering.
that is soo cool !!
This is amazing. 1mm is just enough to make it practical.
This technology is the first step towards giving concrete its consciousness.
The cement animation is soooooo cuteeeeee :DD
Yeeeeaa
Relaxing animation & voice💖
I love your lil concrete guy
Nice animation, interesting contents
Interesting topic. But how about the strength of healed concrete? Is it going to be fully restored to the initial condition?
wow, i am impressed.
so awesome
Please upload the history of umbrella and this animation is very good
I never thought about self healing concrete......thx for new thought
It's funny how I just watched Final Destination 5 yesterday and wondered how we can avoid incident like this in the future.
Wow a new animation style i like it
All I know is that my mother's childhood home; that had sprawling concrete, stands to this day.
Do a next video in fast travel ways or the cheapest way to create roads
(If they exist)
Damn, that animation!
*I Love This Channel*
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.
Oooo thats so great....
Learnt something new and I can sleep peacefully
Thank you UA-cam Recommendation
Woah, this animation sucked me in. Ted-Ed is UA-cam’s fastest evolving channel. 👍🏽👏🏽👏🏽👏🏽 I love learning here.
So you're saying the animation sucks? 😉
Ted's animation has got better.
