Abstract

An attempt was undertaken to elevate the efficacy of Engineered Cementitious Composites (ECC) mixes by inclusion of silica fume alongside mono fiber and hybrid fiber in this study. Totally, six mixes were prepared with low modulus and high modulus fiber. The initial three mixtures consist of mono fiber engineered cementitious composites (MFECC), incorporating Poly Vinyl Alcohol (PVA), Polypropylene (PP), and Glass fiber, each with a 2% volume fraction. The remaining three mixtures were formulated as hybrid fiber engineered cementitious composites (HFECC), combining PVA (1%) and PP (1%), PP (1%) and Glass (1%), and lastly, PVA (1%) and Glass (1%). In addition, all six mixtures were consistently maintained with a fixed composition comprising 40% silica fume, 30% fly ash, 80% M-sand, a water-to-binder ratio of 0.35, and 1% superplasticizer. The findings suggest that within the examined compositions, MFECC reinforced with 2.0% PVA fiber and HFECC reinforced with 1% PVA fiber and 1% glass fiber exhibit more significant strength characteristics than other mixtures.
