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...

Polymeric capsules can have an advantage over glass capsules used up to now as proof-of-concept carriers in self-healing concrete. They allow easier processing and afford the possibility to fine tune their mechanical properties. Out of the multiple requirements for capsules used in this context, the capability of rupturing when crossed by a...

Previous research showed fracture failure in the outsole of sports footwear. There was no method available for the quantification of the material behavior in with this failure mechanism. Therefor the goal of this research was to develop a mechanical test method for quantification of fatigue fracture behavior of a material when a crack is present...

Thermal barrier coatings (TBC) are often applied to hot components of modern turbojet engines. These coatings increase the performance of the engine and enhance the lifetime of its structural components. Thus, improving the TBC lifetime is related with a reduction of maintenance costs and increased reliability. As an alternative to conventional...

Traditional polyetherimides (PEIs) are commonly synthesized from an aromatic diamine and an aromatic dianhydride (e.g., 3,4′-oxidianiline (ODA) and 4,4′-oxidiphtalic anhydride (ODPA)) leading to the imide linkage and outstanding chemical, thermal and mechanical properties yet lacking any self-healing functionality. In this work, we have replaced...

A novel method to encapsulate MoSi2B healing particles was explored via in situ shell formation in yttria-stabilised zirconia thermal barrier coatings (YSZ-BCs). The shell formation was analysed for MoSi2B healing particles alloyed with 2, 6 and 12 wt% Al. According to oxidation kinetics study at 1100˚C using thermogravimetry, MoSi2B-12 wt% Al...

MAX-phase materials, a class of ternary carbides and nitrides that combine favorable properties of metals (conductivity and toughness) and ceramics (high temperature strength) have been shown to autonomously heal micro-cracks by high temperature oxidation. The investigation of Ta and Al containing MAX phases (Ta2AlC & Ta4AlC3) could render self...

This paper explores the potential use of compartmented alginate fibres as a new method of incorporating rejuvenators into asphalt pavement mixtures. The compartmented fibres are employed to locally distribute the rejuvenator and to overcome the problems associated with spherical capsules and hollow fibres. The work presents proof of concept of...

Inspired by the state of the art and the recent advances in the field of self-healing corrosion protective coatings, the thesis entitled “Self-healing corrosion protective sol-gel coatings” addresses novel routes to self-healing corrosion protective sol-gel coatings via extrinsic and intrinsic healing approaches. The employed approaches aim at...

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...

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...

Closure of surface cracks by self-healing of conventional and MAX phase ceramics under realistic turbulent combustion chamber conditions is presented. Three ceramics namely; Al<sub>2</sub>O<sub>3</sub>, Ti<sub>2</sub>AlC and Cr<sub>2</sub>AlC are investigated. Healing was achieved in Al<sub>2</sub>O<sub>3</sub> by even dispersion of TiC...

This work reports on the healing of early stage fatigue damage in ionomer/nano-particulate composites. A series of poly(ethylene-co-methacrylic acid) zinc ionomer/Fe3O4 nanoparticle composites with varying amounts of ionic clusters were developed and subjected to different levels of fatigue loading. The initiated damage was healed upon localized...

To increase lifetime of the protective thermal barrier coatings (TBC) in jet engines and other gas turbines, a self-healing approach based on MoSi2 healing particle addition is considered. However, due to rapid oxygen transport in yttria-stabilized zirconia (YSZ), a common TBC material, premature oxidation is a major problem. This thesis...

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...

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...

The aim of this thesis is to execute a bottom-up design of the intrinsically self-healing nanocomposites. We briefly introduced the self-healing materials in chapter 1, covering classification and basic self-healing mechanism. In chapter 2, we have synthesized polyborosiloxane (PBS) according to the last century recipe as the self-healing...

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...
