Hilloulin, B. (author), Grondin, F. (author), Matallah, M. (author), Loukili, A. (author)Cracks, caused by shrinkage or external loading, reduce the durability of concrete structures as aggressive substances can easily enter in the capillary network of the cementitious matrix. Natural autogenous healing ability of concrete by further hydration or precipitation has been studied experimentally for many years. Autogenous healing of...conference paper 2013

Yabuki, A. (author), Sakai, M. (author)A self-healing corrosion protective coating was developed using TiO2 particles and casein as pH-sensitive organic agents that is also environmentally friendly materials. A film structured of TiO2 particles was formed on a substrate (magnesium alloy) by dip-coating followed by immersion in a casein solution. Casein was inserted and fixed in the...conference paper 2013

Palin, D. (author), Wiktor, V. (author), Jonkers, H.M. (author)Marine concrete structures are exposed to one of the most hostile of natural environments. Many physical and chemical phenomena are usually interdependent and mutually reinforcing in the deterioration of marine exposed concrete: expansion and microcracking due to physical effects increases concrete permeability paving the way for harmful...conference paper 2013

Sugiyama, S. (author), Nakao, W. (author)The alumina fiber reinforced alumina containing the interlayer of SiC as healing agent was found to have self-healing ability for the delimitation of the fiber/matrix interface. Main crack in the composite is branched to fiber/matrix interface when the main crack reached the interface, because the interlayer has lower strength than those of the...conference paper 2013

Koper, G.J.M. (author), Boekhoven, J. (author), Hendriksen, W.E. (author), Eelkema, R. (author), Van Esch, J.H. (author)Self-assembled systems formed of micelles or vesicles have frequently been discussed as model systems for self-healing materials because their structure is dictated by thermodynamics and hence they quickly restore upon perturbation. In this aspect, they mimic many natural systems such as biological cells. However, in contrast to most synthetic...conference paper 2013

Brochu, A.B.W. (author), Evans, G.A. (author), Reichert, W.M. (author)One of the most broadly reported self-healing schemes is that pioneered by White and Sottos et al. in which a polymer matrix is co-embedded with a catalyst and microcapsules containing a reactive healing agent. Although this field has been steadily growing over the past 10 years, little discussion of extension into biomaterials has taken place...conference paper 2013

Lucas, S.S. (author), Nellesen, A. (author), Von Tapavicza, M. (author)In the last decade, an increasing attention has been given to the development of repairing capabilities in materials, with an emphasis in specific strategies that can promote self-healing, with or without external triggers. Self-healing has opened several new possibilities, especially in applications where long-term reliability is demanded and...conference paper 2013

Shen, L. (author), Li, S.B. (author), Van der Zwaag, S. (author), Sloof, W.G. (author)The oxidation crack healing of Cr2AlC and Cr2(Al,Si)C was studied and compared with known healing of Ti2AlC. The oxidation induced crack healing of Ti2AlC is relatively fast and leads to full strength recovery, but the oxidation product contains besides ?-Al2O3 also undesired TiO2. However, when oxidizing Cr2AlC only ?-Al2O3 is formed, but full...conference paper 2013

Brancart, J. (author), Scheltjes, G. (author), Diaz, M.M. (author), Van Mele, B. (author), Van Assche, G. (author)Research in the field of smart materials that exhibit self-repair mechanisms has greatly expanded over the last few years. This is especially true for polymers and polymer composite materials. One class of self-healing polymer materials is the reversible polymer network systems that use dynamic covalent bonds as a means to repair sustained...conference paper 2013

Everitt, D.T. (author), Coope, T.S. (author), Bond, I.P. (author), Trask, R.S. (author), Wass, D.F. (author)Self-healing polymers typically feature monomer and catalyst either dispersed within a host matrix, or encapsulated within hollow vessels. Unprotected highly active catalysts, sensitive to air and moisture, can readily react with amine cross-linking agents during the cure of reactive prepolymers e.g. epoxy resins. Therefore, catalysts stable to...conference paper 2013

Farle, A. (author), Van der Zwaag, S. (author), Sloof, W.G. (author)The reduction of maintenance and replacement work costs is an important driving force in the development of high temperature materials (T>800 °C) that can autonomously heal damage as a result of local cracks. In recent years some potential routes involving the addition of sacrificial particles have been identified, yet these systems have the...conference paper 2013

(author)Reclaimed Asphalt (RA) is one of the largest fractions of raw materials used in road construction today. Probably over 90% of the total RA in the Netherlands is being reused in new asphalt constructions. RA contains aggregates coated with very hard bitumen (penetration grade of 10-20). During service, the bituminous binder loses its flexibility...conference paper 2013

(author)Self-healing concrete is regarded as a promising solution to reduce the high maintenance and repair cost of concrete infrastructure. Due to the limited autogenous healing capacity of concrete as such, additives are needed to enhance its self-healing properties. Among various strategies, microbial-based self-healing has gained increasing...conference paper 2013

Based on fracture mechanics theories, the resistance to damage and the cracking recovery can be an indication of healing performance. Experimentally, the cracking behavior is quantified by measuring the fracture energy of...conference paper 2013
