In this study, an effort was taken to progress the performance of Engineered Cementitious Composites [ECC] mix, by incorporating two different fibers. Five different proportions were subjected to investigation, in this three different proportions were developed with single fiber with 2.0% volume fraction, other two proportions were with two types of fibers. Hybrid ECC proportions were organized through the mixture of low-modulus fibers [poly(vinyl alcohol) fiber] and high-modulus fibers [steel and glass fibers]. Three proportions were made with metallic, glass fiber and poly vinyl alcohol fiber. The hybridation proportions were made with a 2/3 fraction of poly vinyl alcohol fiber and 1/3 fraction of the metal fiber in 2.0% of volume fraction and accompanied with poly vinyl alcohol fi ber 2/3 fraction and 1/3 fraction of glass fiber. This procedure has a good rate of success in tensile and bending behavior of ECC mix. From this effort, it was concluded that poly(vinyl alcohol) fiber 2/3 fraction and 1/3 fraction of glass fiber in 2.0% volume fraction, displayed reasonable traits.
