by In the field of hydraulic engineering, concrete cracks are like a “chronic cancer”, and traditional repair techniques are like “surgical procedures”.
Not only do they cost huge amounts of money (global annual repair costs exceed billions of dollars), but they also fall into a vicious cycle of “repairing cracks, cracking and repairing” due to repeated cracking.
The emergence of self-healing concrete, with its “life like” intelligent healing ability, is sparking a disruptive material revolution – shifting concrete from “passive treatment” to “active immunity”, completely rewriting the rules of engineering durability.
