Abstract

Abstract: The depletion of natural sand and gravel aggregates and the insufficient durability of concrete structures present dual challenges that constrain the sustainable development of modern civil engineering. Self-healing artificial aggregate concrete (SHAAC) provides a green solution for the industry by recycling solid waste. SHAAC achieves autonomous crack repair through the encapsulation of healing agents. Combining the advantages of extended service life and reduced maintenance costs, SHAAC is positioned as a significant direction for the development of intelligent building materials. This paper systematically reviewed the latest research progress in the field of SHAAC, summarized the core design concepts and preparation processes of self-healing artificial aggregates. The self-healing processes and their synergistic effects were analyzed in depth. Furthermore, the self-healing effectiveness of SHAAC were comprehensively evaluated, focusing on the mechanical property recovery, crack healing effectiveness, and durability enhancement. Finally, this paper discussed the key challenges currently faced, including triggering precision, long-term stability of remediation efficiency, adaptability to complex environments and cost effectiveness, and outlined future research directions and application prospects.

Key words: artificial aggregate concrete, crack self-healing, solid waste recycling, durability, intelligent building material
