【 摘 要 】

Cementitious materials are the fundamental element in the field of civil construction. While due to its brittle nature, cracking of cementitious material at multi-scales could pose a threaten to the safety and durability of concrete structure. To solve this congenital problem, bio-mimic self-healing in cementitious materials was proposed and gradually demonstrated its great potential. In this review, two big categories of self-healing, autonomous and autogenous self-heaing, with its corresponding up-to-date healing stratergies were introduced. The merits and limits of different healing strategies were concluded. It is believed that this review could shed light to the realization of practical application self-healing concept in cementitious materials.
