Self healing concrete and asphalt: Erik Schlangen at TEDxDelft

Показать описание

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.

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.

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)

Will this product work in the US? If so, our construction company would love to test it on some road here in SC.

elijahisaiahx

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

ItsLeesus

Can they make those materials conductive with pressure because self healing material is batteries

sampleoffers

by bacteria or not ?
what type of bacteria ? & type of perciptations ?

minsciences

Can I show my project with pattern right sir
How to go about with it

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.

If you look closely, the crack was still there. What exactly does this do?

wheelmanjosh

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.
