Abstract: Autogenous healing in concrete occurs when hairline cracks in concrete repairs themselves through reactions in presence of water. This paper presents a review on an enhancement of autogenous healing of concrete using different supplementary cementitious materials (SCMs). The supplementary cementitious materials such as fly ash and ground-granulated blast-furnace slag (GGBS) reacts with calcium hydroxide. These materials in terms which delayed reactions, thus being more probable that it remains a reaction capability when a crack appears. In this paper, a review has been carried out on the properties of concrete such as mechanical properties, durability properties and crack closure. From the study, it is concluded that introducing supplementary cementitious materials improves autogenous healing of concrete
