An Engineered Cementitious composite is a high ductile cementitious composite which possess property of high crack resistance, with a tensile strain capacity which surpasses the property of normal concrete. Engineered Cementitious Composites are similar to that of a Fiber Reinforced Concrete. But in ECC the fiber percentage is optimized to get the better performance and the absence of coarse aggregates reduces the transition zone effect thus altering the behavior of ECC and also in ECC the mineral admixtures are added to reduce the effect of the obscene of coarse aggregates which cause the decrease of volume. As the bond between the fiber and the matrix is found to play an important role in behavior of ECC. In this experiment an attempt is made to study the interaction of poly propylene and glass fibers with the matrix prepared by incorporating the different mineral admixture such as Metakaolin and fly ash.In this experiment flexural tests were carried out to study the mechanical behavior and to evaluate the behavior with different fibers with the percentage varying between 1% to 2% in the interval of 0.25% and their interaction with different mineral admixtures. It is observed that the control mixes show no deflection whereas glass fiber in Metakaolin with 1% of fibers had shown a good deflection and the same fibers in fly ash shown good deflection at fibers content of 2% whereas poly propylene fiber in Metakaolin with 1.25% of fibers had shown a good deflection and the same fibers in fly ash shown good deflection at fibers content of 1.75%.
