In the human body, small wounds are easily treated by the body itself, requiring no further care. For bigger wounds to be healed, the body may need outside assistance. Concrete is like a living body, in that it can self-heal its own small wounds (cracks) as an intrinsic characteristic. However, cracks do not heal easily in conventional concrete due to its rather brittle nature, which calls into question the effectiveness of self-healing in conventional concrete materials with no control over crack formation.
