Concrete is the most used man-made material in the world, many infrastructures around the world uses concrete. However, concrete is strong in compression and weak in tension. Concrete is brittle and forms cracks when it experiences a large amount of force acting on it. Hence, Engineered Cementitious Composites (ECC) are introduced. ECC can help improve the lifespan and the strength of concrete. However, more research can be done on ECC to help improve further. Thus, this project explores the development of ECC. The study and development of the ECC will be done through designing, casting and testing of new mix designs. To enhance the strength of ECC, research will be done through the use of fibers and modification of the fiber surface as well as with the help of expansive agent. The aim of the study is to design fiber-matrix interface to help develop bio-inspired bendable fiber reinforced composites, which can help to improve performance in the future. The testing that will be done for this experiment includes compression testing, fiber pullout test and also nano-indentation test. Conclusions will be drawn based on the results obtained from the tests.
