In recent studies, it has been recognized that concrete deterioration is accelerated by the growth of fine cracks of a few micron meters in width induced by dry shrinkage and/or freezing damage. There have been great expectations for research on concrete that self-heals these fine cracks. Recent research (for example, Taniguchi et al. in the 3rd...

Self-healing concrete (SHC) can heal itself from cracks and other minor imperfections and thus prolong the life of the material itself and structure. In plain and reinforced concrete structures, fatigue is one of the major causes of both material and structural failures. Under the moving load due to traffic, it is not only the relatively simple...

Since self-healing of cracks is able to improve the durability of concrete structures, it has attracted much attention in the recent years. As known, in concrete matrix there are large amounts of cement grains remaining unhydrated, particularly in high performance concrete. Further hydration of these unhydrated cement grains has potential to...

Cementitious materials are sensitive to crack formation and it would be beneficial if the material could stop the crack propagation, repair the damage and reach again the original liquid-tightness and/or strength. Therefore, a cementitious material with synthetic microfibres and superabsorbent polymers (SAPs) is proposed. Upon crack formation,...

Ethylene-co-methacrylic acid (EMAA) based ionomers have thermo-mechanical properties strongly dependent on neutralization level of acid groups. Research revealed also how these materials are able to heal after ballistic impacts. In order to better understand the role of neutralization level on the Self-Healing (SH) behaviour, mechanical and...

Research has been carried out with the aim of better understanding the relevant properties of materials to be used in a new self-healing cementitious composite material system. The system consists of shape memory polymer tendons embedded within a cementitious matrix, upon heat activation these tendons undergo a shrinkage process which closes any...

Concrete cracking is inevitable, and can be the result of one or a combination of factors such as dry shrinkage, thermal contraction, fatigue, and embedded steel corrosion. The presence of cracks leads to further deterioration, service life reduction of concrete infrastructure, and frequent maintenance and repairs. These challenges can be...

In order to limit the release of CO2 produced in cement manufacturing, clinker (the major cement component) is often partially replaced by mineral admixtures like blastfurnace slag. The use of mineral admixtures presents different advantages such as the recycling of industrial waste and the improvement of different material properties ...

Recent developments in self-healing technology inspired by natural biological materials have the potential to dramatically improve the performance and durability of cementitious materials. These self-healing cementitious materials comprise artificial flow networks embedded within the cementitious matrix that upon damage release healing agents...

Structural ceramics like alumina are usually brittle and sensitive to flaws leading to a reduction in their mechanical properties. This situation is worsened by machining prior to service and during service by contact, which introduces micro cracks and hidden damages. Crack damage can easily be developed in such ceramics when loaded, which often...

Bacteria induced calcite precipitation has been proven to be effective in making concrete structure self-healing. In Microlab TU Delft, the concept has been enhanced by developing a liquid bacteria-based concrete repair system. The solution contains calcite precipitating bacteria, nutrients and buffer compound which may demonstrate high...

A new approach to self-healing systems is presented that aims to overcome the inherent drawbacks of conventional liquid resin based healing systems within composites. Finite embedded systems offer limited healing potential for small volume delaminations and as such cannot effectively heal large damage volumes often associated with shear damaged...
