Savija, B. (author), Schlangen, E. (author)An experimental study of the influence of autogeneous healing on chloride ingress in cracked concrete is presented. In the study, two concrete mixtures (a Portland cement mix and a blast furnace slag mix), two healing regimes (submerged and fog room regime), two cracking ages (14 and 28 days), and multiple crack widths are used as parameters. An...journal article 2016

Qiu, J. (author), Van de Ven, M. (author), Wu, S. (author), Yu, J. (author), Molenaar, A. (author)The self-healing capability of bituminous materials has been known for many years. Researches were mostly focused on the self healing behaviour during load repetitions. The tests are either time consuming and/or complex. In this paper, a simple self healing test procedure is presented combining the fracture-healing-re-fracture test (FHR) with...journal article 2012

Vermolen, F.J. (author), Javierre, E. (author)A simplified finite-element model for wound healing is proposed. The model takes into account the sequential steps of dermal regeneration, wound contraction, angiogenesis and wound closure. An innovation in the present study is the combination of the aforementioned partially overlapping processes, which can be used to deliver novel insights into...journal article 2011

García, Á. (author), Schlangen, E. (author), Van de Ven, M. (author), Van Vliet, D. (author)The objective of this research is to examine the induction heating of mastic through the addition of electrically conductive fillers and fibers (graphite and steel wool), and to prove that this material can be healed with induction energy. The effect of fibers content, sand–bitumen ratio and the combination of fillers and fibers on the induction...journal article

Wiktor, V. (author), Jonkers, H.M. (author)La formation d’un réseau continu de fissures contribue à l’augmentation de la perméabilité du béton, réduisant ainsi de manière importante sa résistance à l’attaque d’agents agressifs dissous dans l’eau. Afin d’augmenter la capacité de cicatrisation autogène du béton, certains agents cicatrisants spécifiques peuvent être incorporés dans la...journal article 2011

De Koster, S.A.L. (author), Mors, R.M. (author), Nugteren, H.W. (author), Jonkers, H.M. (author), Meesters, G.M.H. (author), Van Ommen, J.R. (author)Concrete structures are often reinforced with steel. In order for the reinforcement to take over tensile forces, concrete has to crack. Through such cracks, water and compounds that are harmful to concrete can enter. This can cause durability issues like leakage, concrete degradation and reinforcement corrosion. In situ repair of cracks is often...journal article 2015

Sisomphon, K. (author), Copuroglu, O. (author), Fraaij, A. (author)This paper studies the potential of using expanded clay lightweight aggregate impregnated with sodium monofluorophosphate (Na2FPO3) solution which is eventually encapsulated by a cement paste layer to produce a self-healing system in blast furnace slag cement mortars. It was found that the technique significantly improved the quality of the...journal article 2011

Van den Bergh, W. (author), Van de Ven, M.F.C. (author)For asphalt pavement design in Belgium, healing is taken into account as a standard shift factor, representing the effect of rest periods between loadings of traffic. Because nowadays Reclaimed Asphalt Aggregate (RA) is widely used in hot mixtures, a new validation of the healing factor is needed. Given the lack of test results and a standard...journal article 2012

Sangadji, S. (author), Schlangen, H.E.J.G. (author)To repair concrete cracks in difficult or dangerous conditions such as underground structures or hazardous liquid containers, self healing mechanism is a promising alternative method. 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 ...journal article 2013

Garcia Espallargas, S.J. (author)Intrinsic and extrinsic self-healing strategies can be employed to mitigate the effects of local damage in order to (partially) restore a lost property or functionality and to avoid premature catastrophic failure of the whole system. It is well known that polymer architecture has a crucial influence on mechanical, physical and thermal properties...journal article 2014

Vermolen, F.J. (author)The paper deals with a compilation of several of our modelling studies on particle methods used for simulation of wound healing and tumor growth processes. The paper serves as an introduction of our modelling approaches to researchers with interest in biological cell-based models that use particle-based modelling approaches. The particles that...journal article 2015

Schmets, A.J.M. (author)The use of a material for a specific application is governed by considerations on the expected conditions during its lifetime. For aerospace applications for instance, lightness, reliability and thermal stability ofthe material are of major importance. No material will ever possess all the desired properties at the same time. Therefore the...journal article 2006

Andreykiv, A. (author), Van Keulen, F. (author), Prendergast, P.J. (author)Modelling the course of healing of a long bone subjected to loading has been the subject of several investigations. These have succeeded in predicting the differentiation of tissues in the callus in response to a static mechanical load and the diffusion of biological factors. In this paper an approach is presented which includes both...journal article 2007

Jonkers, H.M. (author)A typical durability-related phenomenon in many concrete constructions is crack formation. While larger cracks hamper structural integrity, also smaller sub-millimeter sized cracks may result in durability problems as particularly connected cracks increase matrix permeability. Ingress water and chemicals can cause premature matrix degradation...journal article 2011

García, A. (author), Schlangen, E. (author), Van de Ven, M. (author), Van Vliet, D. (author)It is well known that the healing rates of asphalt courses increase with the temperature. A new method, induction heating, is used in this paper to increase the lifetime of asphalt concrete pavements. Mastic will be first made electrically conductive by the addition of conductive fibers. Then it will be heated via induction energy. This will...journal article

Lubelli, B. (author), Nijland, T.G. (author), Van Hees, R.P.J. (author)Lime mortars have, up to a certain extent, a self-healing capacity which may contribute to their durability. Self-healing in lime mortars consists of a process of dissolution, transport and re-precipitation of calcium compounds to heal cracks and fissures. The spontaneous occurrence of self-healing in lime-based mortars is a well known...journal article 2011
