| Summary: | This dissertation presents a systematic literature review on the effect of fly ash in self-healing concrete. The objective of this review is to investigate the effect of fly ash in self-healing concrete and studies the performance of fly ash in self-healing concrete. This review also distinguishes the gap of knowledge in the application of fly ash in the autogenous self-healing ability of the concrete. Self-healing is the capacity of the concrete to repair internal damage without outside intervention. Yet, the formation of ettringite will help the self-healing ability of the concrete to fill the cracks. Therefore, there were 12 articles had been identified in this review from Scopus and ScienceDirect database after meeting the inclusion criteria. Using systematic search strategies, irrelevant papers were screened out, and the article quality evaluation was employed to avoid publications with poor methodological quality. In this review, the effect and performance of fly ash were discussed. In this review, fly ash affects the sorptivity, permeability, crack width, compressive strength and self-healing product and environment. The performance of fly ash was influenced by the exposure condition, curing time, initial crack width and the content of fly ash.
