‘…and of all the remarkable properties of natural materials, one is truly exceptional – that of the ability for self-repair.’
Imagine that metal skin in satellite hit by space debris creating a puncture or hazardous liquid waste container fractured under its own pressure and without any human intervention those holes and cracks immediately healed. Sounds like science fiction! In future scientist believed that engineered materials will heal itself during their service life. Inspired by nature researchers develop several concepts and techniques by embedding capsule, creating vascular system, putting catalyst agent, and enhancing intrinsic self-healing capacity of material which have been used for different materials ranging from polymer to ceramic.
One of the proposed ideas at Microlab, Materials and Environment Section, CEG TU Delft is to make a porous layer inside of concrete structure that can be infused with healing material. This research aims to imitate the bone self healing process by putting porous concrete internally in the concrete structure to create a porous network similar to ‘spongious bone’. When crack is formed and detected by sensors, healing agent can be infused into the porous network so as to fill up voids and seal a crack or cracks in the concrete body. A method is proposed to turn the manual healing onto a completely automated self healing system.
Kopi Delft 15 Juni 2012 (Cooming Soon)
In Kolokium Pelajar Indonesia (Kopi) PPI Delft we will introduce the general overview of self-healing material technology and in particular will focus on our own work; self-healing concrete. Porous Concrete Network, a patent pending novel technology which is currently developed will be explained in details.
Meet the Speaker:
Senot Sangadji is a doctoral candidate at Delft University of Technology. His research concerns on self-healing mechanism and processes of cement-based materials. He particularly focuses on the development of porous network concrete, a novel method of to make concrete structures self healing. He received his Master degree in structural engineering from Institut Teknologi Bandung, Indonesia in 2001 with research of, ‘design, production, and testing of aero-elastic model of long-span cable supported bridge’. Before he joined the research group in TU Delft, he was a junior lecturer in Civil Engineering Department, UNS Indonesia where he taught and conducted research in structural analysis, structural dynamics, and earthquake engineering.
