Wu, Xintong (author), Huang, Haoliang (author), Liu, Hao (author), Hu, Jie (author), Wei, Jiangxiong (author), Yu, Qijun (author)In this study, a new concept on self healing of cracks that the ingressive ions in the crack is chemically bound to improve the self-healing efficiency was proposed for cracked cementitious materials in a marine environment. Thermodynamic modeling was performed to determine the appropriate masses and ratio of Ca2+ and Al3+ provided by chemical...conference paper 2021

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...conference paper 2018

Granneman, S.J.C. (author), Lubelli, B. (author), van Hees, R.P.J. (author)This paper presents the most important results of a research project which<br/>focused on the use of crystallization modifiers mixed in lime mortar to mitigate<br/>salt crystallization damage. The research focused on two of the most damaging<br/>salts, sodium chloride and sodium sulfate, and suitable crystallization modifiers (sodium...conference paper 2017

Van der Zwaag, S. (author), Zhang, S. (author), Fang, H. (author), Bruck, E. (author), Van Dijk, N.H. (author)We report the main findings of our work on the behaviour of binary Fe-Cu and Fe-Au model alloys designed to explore routes to create new creep resistant steels having an in-built ability to autonomously fill creep induced porosity at grain boundaries. The alloying elements were selected on the basis of their ability to be brought in...conference paper 2016

Romero Rodriguez, C. (author), Chaves Figueiredo, S. (author), Chiaia, B. (author), Schlangen, E. (author)Cracking in concrete structures compromises the durability and functionality of the structures themselves. Different kinds of self-healing concretes, less or more sophisticated, have been developed in the past ten years to overcome early cracks in structures. An experimental study of a novel self-healing concrete is presented. Bitumen, used as...conference paper 2016

Sierra Beltran, M.G. (author), Jonkers, H.M. (author), Mors, R.M. (author), Mera-Ortiz, W. (author)This paper describes the first field application of self-healing concrete with alkaliphilic spore-forming bacteria and reinforced with natural fibres. The application took place in the highlands in Ecuador in July 2014. The concrete was cast as linings for an irrigation canal that transports water from glaciers in the Andean mountains to...conference paper 2015

Savija, B. (author), Schlangen, E. (author)Concrete structures are commonly cracked when in service. To overcome issues arising from cracking, self-healing concrete is being developed. Together with the development of the material, techniques to verify and quantify self-healing are being developed. A number of destructive techniques have been used in the past. It would be beneficial to...conference paper 2015

Huang, H. (author), Ye, G. (author)In this paper, different mechanisms of self-healing, i.e. self-healing based on adhesive agents, self-healing based on bacteria, self-healing based on autogenous self-healing were described. Their required conditions were summarized. The previous investigations showed that all mechanisms of self-healing are effective to some extend under...conference paper 2014

Cordioli, C. (author), Bauters, E. (author), Muselle, T. (author), Hubin, A. (author)Commonly coatings are used to protect metals from corrosion. Different types of coatings are available and according to their characteristics they provide different levels of protection. In order to evaluate the performance of the coating, it is fundamental to have a methodology that is reliable and efficient even when applied to different kinds...conference paper 2013

Mors, R.M. (author), Jonkers, H.M. (author)A functional experimental concrete system has been developed in our lab, in which a two component bacteria-based healing agent contained in a protective reservoir is included in the concrete mixture. Incorporated bacteria have the potential to produce copious amounts of calcium carbonate based crystals from supplied mineral precursor compounds....conference paper 2013

Promising results were obtained with PEObPS nano-formations, both in terms of enhanced bulk matrix properties and improved steel corrosion resistance. Recent research has been focusing on a cheaper and commercially...conference paper 2013

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

Zhang, Z. (author), Qian, S. (author)Crack is called the intrinsic flaw of concrete that is inevitable for concrete infrastructures during their service life. The presence of crack offer aggressive agent access to pass through, which has a direct impact on durability, therefore resulting in shortened service life. Nevertheless, the influence of crack on the durability can be...conference paper 2013
