The addition of supplementary cementitious materials and fiber plays an important role in the mechanical and durability performance of ECC matrix. In the present research work, the assessment of the performance of ECC matrix with the utilization of iron industry waste and microfibers has been done. Three types of microfibers, i.e., polyvinyl alcohol (PVA) fiber, polyester (PET) fiber, and microsteel (MSE) fiber, were used at various percentages in hybridization to prepare total seven mixes. First, PVA was switched by PET fiber at dosages 5%, 10%, 15%, 20%, and 25% and afterwards another 25% by MSE fiber. The performance of various matrix proportions was judged based on the flexural response, electrical resistivity, air permeability, and sorptivity characteristics to introduce sustainable and cost effective ECC matrix. Test results revealed that hybridization of fibers enhanced the flexural and durability performance of ECC and also produced a cost effective and sustainable ECC matrix. [ABSTRACT FROM AUTHOR]

• Locally available fine river sand (RS) was used instead of micro silica sand (MS) to produce the ECC matrix. • Stone slurry powder (SSP) waste was incorporated as partial substitution of fine aggregates. • Mechanical, durability and environmental impact assessment of ECC mixes were evaluated. • SSP can be utilized as alternate of RS and MS to produce the durable and eco-friendly ECC. The current investigation focuses on utilization of stone slurry powder waste (SSP) in engineered cementitious composite (ECC) as alternate substitution of locally available river sand (RS) and micro silica sand (MS). Performance of various ECC mixes was judged by assessing the compressive, tensile, flexural, electrical resistivity (ER), air permeability, sorptivity and environmental characteristics. The effect of chemical exposure on ECC under chloride, sulphate and combined (chloride-sulphate) immersion was assessed through compressive strength, tensile response and ER behaviour. From this study, it has been concluded that the ECC containing SSP promote the superb characteristics of ECC under normal and chemical exposure conditions. [ABSTRACT FROM AUTHOR]
