A decade of research on self-healing concrete

The main findings of a decade of research on the design and development of the first self-healing concrete are summarized in this chapter. The autonomous healing concept is introduced, and plethora of design campaigns are enlisted. Healing agent encapsulation and agent tubes vascular networks are reported as the most efficient healing configurations for laboratory-scale and real-size applications respectively. Crack formation, closure after healing and further damage are phenomena tracked by using advanced experimental monitoring methods and their performance is critically revised. The effect of self-healing technology on material mechanical response, durability and long-term response to damage are critically discussed. The study contributes to the open discussion in scientific research community on the self-healing concrete upscaling feasibility and finally it aims to contribute as a base for the future studies dealing with self-healing concrete design optimization.
