Concrete which can withstand high bending pressures is known as bendable concrete.Engineered Cementitious Composite (ECC) is another term for it because as concrete bends, fiber moves inside of it to provide it with enough strength to prevent breaking. Engineered cementitious composite, a performance-enhancing substance having a volume percentage of 2% discontinuous fiber, cement, fine aggregate, fly ash and chemical admixture.To make the concrete more flexible, cementitious materials and hybrid fibers such as steel-PVA (Polyvinyl Alcohol) fiber, steel-carbon fiber, and carbon-PVA fiber are used in place of coarse aggregate. A review paper is done based on the mechanical properties, Micro-structure properties and ECC’s durability properties. Nearly 50 papers are reviewed and presented in this paper
