In October 2012, Prof. rik Schlangen gave a lecture in TEDxDelft on self healing concrete and asphalt. Here is the video:
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 fibers and induction energy.
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.
