Abstract. Self-repairing means ability to the total or partial recovering of the properties which were worsened as a consequence of damage of the material. The subject of the paper is evaluation of ability to self-repair of a cement composite modified with epoxy resin without a hardener. The methodology of investigation of self-repairing building materials, developed by the authors, has been described, with controllable enforcing of the limited weakening of the material. Also, the self-repair degree has been defined as the measure of self-repairing ability of the building composites. The material model of the epoxy-cement composite has been developed on the basis of the tests results. The material optimization of the composite towards the maximum self-repairing ability has also been carried out. The results of investigation have confirmed the possibility of self-repairing of the cement composite modified with the epoxy resin without hardener. The conclusion and further research needs in the range of the self-repairing epoxy-cement composites have been pointed out.

“…In 1994, Dry developed an active and a passive cracking repair method by smart timed release of polymerizeable chemicals from porous and brittle hollow fibers into cement matrices [18]. As shown in Figure 3 (left), the active cracking repair system contains porous fibers coated with wax and filled with methyl methacrylate.…”

Induction heating method is a well known process to produce heat in a localized area on a susceptible metallic object. High frequency power, a work coil and an ancillary instrument part is the basis of induction heating. It is used in industrial and domestic areas where uniform and rapid heating is absolutely essential. As it is highly needed, in this research work, the effectiveness of induction heating will be verified by different curing methods. Firstly to initiate the asphalt concrete curing by high frequency induction heating so that the concrete become durable, electrically conductive and appropriately adjusted for induction heating, steel wire mesh / GI wire mesh is employed which is a good conductor of electricity. Now when micro cracks are likely to occur in asphalt product, the temperature of the asphalt material can be made high by induction heating of the steel wire mesh / GI wire mesh due to which the micro cracks are repaired itself and cracks are repaired by the increased temperature curing of bitumen by the physical process of diffusion and flow of the material. Consequent upon the repair, pre repair of small cracks, major cracks fail to occur protecting the road and thus ravelling of the road prevented to a great extent.

“…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.
