Self healing concrete and asphalt: Erik Schlangen at TEDxDelft
Вставка
- Опубліковано 4 гру 2012
- Erik Schlangen is Professor "Experimental Micromechanics" and director of the Microlab at Delft University of Technology, faculty of Civil Engineering and Geosciences.
The main research topics of his chair consist of studying mechanical properties of materials to be able to understand failure mechanisms and to develop materials with improved properties. A further focus of his research is the field of chemo-mechanics which tries to study degradation due to coupled chemical and mechanical actions in materials. In 2005 he was amongst the first to develop new materials with self-healing properties. He took the initiative in developing self-healing concrete using Bacteria and he was the inventor of the self-healing Asphalt using steel-wool fibres and induction energy.
He obtained a MSc-degree in Structural Engineering in 1989 from Eindhoven University of Technology and finished his PhD at the Civil Engineering department at Delft University in 1993. During his PhD he developed the Delft Lattice Fracture Model. After a two year Post-doc position in the US, he joined the Materials Research Institute Intron in the Netherlands. In 2003 he returned to Delft to join the Microlab, where he was promoted to Professor in 2012.
He is author of more than 250 journal and conference publications and is very active in international research committees. He is Chairman of the Rilem Technical Committee on self- healing of cement based materials.
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
Thanks to TEDx Talks for engineering talks, Kindly bring more and more research scholar to present their research on TEDx Talks.
There is a concrete that heals itself. It is mixed with a bacteria that creates calcium when the concrete cracks and fills it in.
Is Sporecrete self healing concrete a real thing?
interesting !!! good work Erik
The water laying on the road surface which then being struck by a tire at speed causes cavitation is the main factor for road destruction, so the porous surface is the best structure, but wouldnt the sun every summer at peek heat do pretty much the same thing.
I'm not sure this video has the right title, it's appears to only be self-healing asphalt, not concrete, I've never heard of concrete with bitumen in it, and this technology is directly correlated with bitumen (and mixing in steel threads)
Timmah Asphalt is called Asphalt/Bituminous Concrete, Concrete with cement as the binder is called Cement Concrete (Portland Cement Concrete, if the cement used is Portland Cement)
This is essentially what I thought of for using if cracks form in an O Neil Cylinder, in the Graphene Carbon Fiber/Nanotube Basket, with Graphene carbon fiber/nanotube burs with graphene resin. Just graphene could be poured in with resin and heated up to heat fix everything together.
4 years ago today!
This is very interesting
Will this product work in the US? If so, our construction company would love to test it on some road here in SC.

Can they make those materials conductive with pressure because self healing material is batteries
Can I show my project with pattern right sir
How to go about with it
Not really 'self healing' if you need to use a machine to do it, but I guess it's still better than having to keep laying new road
Lee Allcock the machine only emmulates TIME
and heat...
If you look closely, the crack was still there. What exactly does this do?
+Wheelman Josh
Usually asphalt, or however you want to call this type of "street surface", doesn´t appear as a single square beam.
The crack just visualized a split in the "street surface". These cracks or splits are deadly for the street itself in combination with water and Temperatures. So if you can close those gaps or cracks ..whatever...you prevent the incoming from water and then its expanding in relation to Temperatures.
That´s how I understod this whole thing.
If I´m wrong please let me know !
i want know what is that solution at first he dipped in to
Liquid nitrogen
Terminator house that regenerates itself, The terminator city that regenerates itself. :D
by bacteria or not ?
what type of bacteria ? & type of perciptations ?

I would assume not so good for climates with freeze thaw cycles. That stuff would crumble like stale bread in a New England winter.

wow
now what are you going to do about the HIGH LEVELS of TOXICITY of the substance? IN California, it was one of the first group of Prop 65 Substances--industrial substances in such common use they needed to have serious restrictions put on them. Asphalt exposure changed my life! Toxic Encephalopathy, BLIND & on supplemental oxygen for more than 5 years. I beat what MD's said I'd never beat & got back my sight--I still have neurological issues that demand a constant lifestyle of self-healing.
TIMMY TURNER, YOU WILL NO LONGER HAVE FAIRY ODD PARENTS!
Maybe in the USA, but in the netherlands nah.
How do you get asphalt in your system, did you pulverize it and then inhaled it or something, the fuck.
Ever been at a red light next to an asphalt truck & feel sick? That's cos it's TOXIC. Industrial installations of asphalt (like on a street) in Cali require at least 24 hours notice before installation within 75 feet of a residence--to allow residents a chance to go away during the most dangerous time--when it is mixed, prepped, hot & the fumes are at their most toxic. Read asphalt’s MSDS. & my story’s in my TED bio.
You are supposed to drive on it not eat it.
