Bendable concrete is also defined as engineered cementitious composites because of its great ductility and tight fracture width limitation. ECC mixtures by adding additional Portland cement, silica sand and fly ash, fiber types (polypropylene (PP), and polyvinyl alcohol (PVA)). The objective main aim of the research is to investigate the flexural performance of a series of RC beams that were externally bonded (EB) with steel bars using the engineered cementitious composite (ECC) matrix near-surface mounted technique. A total of 5 RC beams by 1500 mm as a length, 150 mm as width, and 200 mm as height, including one control and four strengthened, were prepared and tested. The test parameters are strengthening configurations and glue matrix (ECC and Epoxy). The test results revealed that ECC is an ideal cement matrix for reinforcement applications where ECC and Epoxy mortar bonded with steel bars are used as exterior reinforcement. As a result of what ECC has a number of attractive properties. The most unique aspect is the high tensile ductility, which is hundreds of times that of concrete while maintaining compressive strengths similar to concrete or high strength.
