Engineered Cementitious Composites are belonging to the ultrahigh performance fiber reinforced composites. Engineered Cementitious Composites are composed of fine grained ingredients like cement, fine sand, fly ash, but don’t coarse aggregate. Presence of cement in the typical Engineered Cementitious Composites mix is nearly 1000 kilograms per cubic meter, which make this material to keep far from the sustainability. The content of fly ash in the mix improves the performance of mechanical properties and durability, however, the percentage of replacement of cement has the optimum up to 30 to 40 %. In this study, an attempt is made to add granulated blast furnace slag to Engineered Cementitious Composites mix replacing the cement, along with fly ash. Five different mix proportions are used in this investigation, from 10%, to 50%, at 10% intervals of the granulated blastfurnace slag, replacing cement. The content of granulated blast-furnace slag exhibit remarkable achievement in the mechanical parameters and impact toughness.
