 The behavior of the new material used in the reinforcement (ECC) is similar to the previously known reinforcement material (epoxy materials).  The strengthened beams results illustrated that RC beam flexural strength varies by the shape of the strengthen method (ECC groove (2*2*100) cm, ECC plate (2*15*100) cm, and ECC U-plate (5*2) + (2*15*100) cm) increased the ultimate load of the strengthened RC beams by about 73.58%, 76.67%, and 78.46% respectively.
