(author)Symposium organised by Ghent University, Department of Structural Engineering and Delft University of Technology, Aerospace Structures & Materials. Materials play an extremely important role in our lives. These materials may be of a very different nature ranging from metals over concrete to polymers and composite materials. They all have in...book 2013

Tabakovic, A. (author), Schlangen, E. (author)This paper presents a unique self-healing system for asphalt pavement which employs compartmented calcium-alginate fibres encapsulating an asphalt binder healing agent (rejuvenator). This system presents a novel method of incorporating rejuvenators into asphalt pavement mixtures. The compartmented fibres are used to distribute the rejuvenator...book chapter 2020

Gaggero, M.B. (author), Korswagen, Paul A. (author), Esposito, R. (author), Rots, J.G. (author)Cracks are one of the most common expressions of damage in masonry structures. Aside from aesthetic issues, they can compromise the overall behaviour of the structure; therefore, they are undesirable and need to be repaired. The repointing technique is traditionally implemented in this context, especially in historical masonry. Nevertheless,...book chapter 2023

Lafont, U.L. (author), Van Zeijl, H. (author), Van der Zwaag, S. (author)In this work, we investigate the formation of self-healing systems that are able to recover more than once more than one (mechanical or other physical) functionality. To this aim composites were created consisting of a polysulfide thermoset rubber matrix having intrinsic self-healing properties filled with thermally/electrically conductive...conference paper 2013

Lafont, U.L. (author), Van Zeijl, H.W. (author), Van der Zwaag, S. (author)While conventional self healing materials focus on the restoration of mechanical properties, newer generations of self healing materials focus on the restoration of other functional (i.e. non-mechanical) properties. Thermal conductivity is an example of an important functional property of a Thermal Interface Material (TIM) for LED’s and...conference paper 2013

Vega Vega, J.M. (author), Van der Zwaag, S. (author), Garcia Espallargas, S.J. (author)Poly(ethylene-co-methacrylic acid) (EMAA) ionomers have shown healing capabilities in both ballistic and static tests. In previous studies it was shown that the degree of crosslinking (clusters) affects (positively or negatively) the healing under impact tests. Moreover, it has also been reported that the modification of the ionomers by...conference paper 2013

Latsuzbaia, R. (author), Negro, E. (author), Koper, G.J.M. (author)Platinum nanoparticles, which are used as catalysts in Proton Exchange Membrane Fuel Cells (PEMFC), tend to degrade after long-term operation. We discriminate the following mechanisms of the degradation: poisoning, migration and coalescence, dissolution, and electrochemical Ostwald ripening. There are two ways to tackle this problem. The first...conference paper 2013

Su, J.F. (author), Qiu, J. (author), Schlangen, H.E.J.G. (author)Preservation and renovation bitumen of pavement is a big problem for the whole world. Traditionally, application rejuvenators is the only one method that can restore the original properties of the pavements. However, some puzzles still restrict its successful usage. Microencapsulation is a promising method to apply rejuvenator in bitumen. These...conference paper 2013

Lubelli, B. (author), Nijland, T.G. (author), Van Hees, R.P.J. (author)In the present research a test procedure was set up to reproduce self-healing on lime-based (both pure calcium and magnesium-calcium) mortar specimens in laboratory. After few months testing, during which the specimens were subjected to wet-dry cycles, thin sections of the specimens were prepared and observed by Polarization and Fluorescence...conference paper 2011

The alloying elements were selected on the basis of their ability to be brought in...conference paper 2016
