Now, most of the capsules used to contain polymeric healing agents in self-healing concrete, are made of glass. However, glass capsules cannot be mixed in concrete and are therefore placed manually into the moulds during concrete casting in laboratory tests. This represents a major drawback for an eventual industrialisation. In this study,...

Encapsulation of reactive agents embedded within a matrix is the most studied concept to develop self-healing materials. The most common approaches employ either a single component with catalyst dispersed in the matrix or a single environment-reactive component for corrosion protection [1]. Recently an approach for corrosion protection based on...

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...

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....

An asphalt mixture is believed to be a partial self-healing material. For asphalt pavement design, this characteristic is taken into account as a shift healing factor. Healing during rest periods will result in a longer structural design life for the mixture in situ, compared to the fatigue life determined with a continuous sinusoidal test in...

Polymeric nano-materials utilization in reinforced concrete, aiming to deal with steel corrosion was developed in previous works. Promising results were obtained with PEO–b–PS 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...

Recently, encapsulated silyl esters have been shown to act as efficient healing agents for self-healing anticorrosive coatings. While the positive protective effects were irrefutable, the actual protection mechanism has not been clarified yet. In this study, x-ray computed ?-tomography and electrochemical impedance spectroscopy have been...

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...

To develop an appropriate method of self-healing for cementitious materials including the right composition and amount of suitable healing agents it is required to investigate the healing efficiency for certain material mixtures. While some researchers evaluate the regain in compressive strength by means of destructive load tests, this method is...

Noncovalent bonds are often reversible and sensitive to external stimuli. Although noncovalent interactions are inherently weak and generally perceived as inadequate to construct macroscopic materials of sufficient integrity and cohesion, the emergence of nanotechnology has shown that the intrinsic weakness of noncovalent interactions can be...

In recent times the development of self-healing polymeric materials is focused on investigations of fast and efficient crosslinking processes. These should either be able to form new highly branched networks in order to restore thus the initial material properties or to enhance existing materials in view of their thermomechanical and...

All polymeric materials are subject to thermal, mechanical as well as chemical degradation and destruction during their lifetime. As new materials are designed, the quest for materials with self-healing properties (i.e.: those which can regenerate similar to living matter, especially after mechanical deformation) is increasing, culminating in...

Previously, we reported a self-replenishing polymer surfaces which recover their lowsurface energy (i.e. hydrophobicity), upon surface damage[1]. Following up, we used a dual experimental-simulation approach to understand in-depth the surface segregation of low surface energy components[2], the self-healing mechanism involved on the surface...

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,...
