Researchers evolved Engineered Cementitious Composite (ECC) in the nineties, which belong to the family of high-performance fibre-reinforced cementitious composites. ECC is additionally known as bendable concrete as a ductile alternative to conventional concrete. ECC requires a huge amount of supplementary cementitious material (fly ash), contributing to sustainable development. In this study, a review of ECC has been studied with supplementary cementitious materials which include fly ash and slag. ECC has better tensile strength, ductility and durability properties than other kinds of fibre reinforced concrete (FRC). The results are primarily based on the properties of ECC with fly ash and slag. This research work affords an exhaustive overview of ECC with the aid of incorporating fly ash and slag as supplementary cementitious substances. The impact of fly ash fineness, the calcium content of fly ash, fly ash content, and slag on various properties of ECC are taken into consideration. Also studied the effect on the strength of ECC with fly ash at increased temperature.
