“…Once the glass fibers were ruptured by the crack, the healing agent, CA, will be released into the cracks of the matrix and finally seal the crack. After that, many researchers have also explored the feasibility of using CA as adhesive agent for self-healing [8,9]. These researches found that CA (superglue) is a suitable healing agent since the one-component agent adhesive is able to flow into and heal finer cracks.…”

Abstract. Cementitious materials are the fundamental element in the field of civil construction. While due to its brittle nature, cracking of cementitious material at multi-scales could pose a threaten to the safety and durability of concrete structure. To solve this congenital problem, bio-mimic self-healing in cementitious materials was proposed and gradually demonstrated its great potential. In this review, two big categories of self-healing, autonomous and autogenous self-heaing, with its corresponding up-to-date healing stratergies were introduced. The merits and limits of different healing strategies were concluded. It is believed that this review could shed light to the realization of practical application self-healing concept in cementitious materials.

“…Fibre reinforced composites based on the hollow fibre concept offer the closest approximation in self healing man-made materials to natural materials with a vascular system. The concept was originally introduced by Dry et al [11][12][13] for concrete using hollow glass fibres filled with a liquid epoxy resin. The concept was later implemented by Trask and Bond [14][15][16] for high performance carbon fibre -epoxy composites.…”

Abstract. Modern man-made engineering materials demonstrate excellent mechanical properties, but the lack of the ability of self healing, i.e. the ability to remove or neutralise microcracks without (much) intentional human interaction, which is typical for most materials as encountered in nature. Such self-healing behaviour requires the presence of mobile species, atoms or molecules, in an otherwise solid material. Upon the occurrence of damage the mobile species directionally flow towards the damage location and once arrived there restores the contact between the two crack faces and the mechanical integrity. This directional flow may occur during regular use conditions (self healing behaviour) or conditions during which the mobility is temporarily increased (stimulated self healing).In this manuscript a brief overview of the routes and mechanisms which have been used to create self healing behaviour in the principal classes of engineering materials: polymers, metals, ceramics, concrete, asphalt, fibre composites, is presented.

Man-made engineering materials generally demonstrate excellent mechanical properties, which often far exceed those of natural materials. However, all such engineering materials lack the ability of self-healing, i.e. the ability to remove or neutralize microcracks without (much) intentional human interaction. This inability is the unintentional consequence of the damage prevention paradigm underlying all current engineering material optimization strategies. The damage management paradigm observed in nature can be reproduced successfully in man-made engineering materials, provided the intrinsic character of the various types of engineering materials is taken into account.
