The crystalline admixture in self-healing concrete is the main topic of a comprehensive literature review presented in this final year project. The purpose of this review is to identify the effect of crystalline admixture inclusion on self-healing concrete. The review also identifies the knowledge gaps in the application of crystalline admixture for self-healing concrete and evaluates the performance of crystalline admixture in selfhealing concrete. For information's future reference, self-healing concrete can automatically repair the crack without any outside assistance to regain strength and durability. Yet, the formation of calcium silicate hydrate (C-S-H) gel will enhance the self-healing helped to fill the crack. Therefore, there were 18 articles had been identified in this review from the Scopus and ScienceDirect database. Systematic searching strategies had been used to screen out irrelevant articles and the article quality assessment was also used to avoid publications of poor methodological quality. In this review, the effect and performance of crystalline admixture were discussed. Results indicated that the healing reaction of the concrete is influenced by the hydration process of the concrete cracks. The effectiveness of the inclusion of crystalline admixture was then examined, and the findings revealed that the conditions of water immersion, water contact, and wet/dry performance performed better than the healing condition of open-air exposure. Crystalline admixture materials are used as hydrophilic materials because of how quickly they react with water. The density of calcium silicate hydrate (C-S-H) is further increased, which prevents or reduces water penetration.
