Concrete is very sensitive to crack formation. As wide cracks endanger the durability, repair may be required. However, these repair works raise the life-cycle cost of concrete as they are labor intensive and because the structure becomes in disuse during repair. In 1994, C. Dry was the first who proposed the intentional introduction of self-healing properties in concrete. In the following years, several researchers started to investigate this topic. The goal of this review is to provide an in-depth comparison of the different self-healing approaches which are available today. Among these approaches, some are aimed at improving the natural mechanism of autogenous crack healing, while others are aimed at modifying concrete by embedding capsules with suitable healing agents so that cracks heal in a completely autonomous way after they appear. In this review, special attention is paid to the types of healing agents and capsules used. In addition, the various methodologies have been evaluated based on the trigger mechanism used and attention has been paid to the properties regained due to self-healing.

Tests and methods of evaluating the self-healing efficiency of concrete: A review (2016, background): “Some polymer base self healing agent have the potential to induce more than 100% regain in compressive strength [77].”
Coupled effects of crack width, slag content, and conditioning alkalinity on autogenous healing of engineered cementitious composites (2016, background): “Despite the obvious advantage in selfhealing efficiency, the amount of required healing compound increases rapidly as crack grows and widens, which causes very high cost [16].”
