As the most widely used building material today, concrete has the advantages of high compressive strength, good durability, and low cost.
However, its inherent brittleness leads to the formation of microcracks during use, which not only reduce the mechanical properties of the material but also provide channels for harmful substances to invade, accelerating structural aging and steel corrosion.
The traditional repair method relies on manual detection and external intervention, which is inefficient and difficult to deal with internal micro damage.
The emergence of self-healing concrete provides a new approach to solving this problem.
