Abstract

Addition of supplementary cementitious materials and fiber play an important role on mechanical and durability performance of ECC matrix. In the present research work assessment of the performance of ECC matrix with the utilization of iron industry waste and micro fibers has been done. Three types of micro fibers i.e. polyvinyl alcohol (PVA) fiber, polyester (PET) fiber and micro steel (MSE) fiber were used at various percentages in hybridization to prepare total seven mixes. First PVA was switched by PET fiber at dosage 5%, 10%, 15%, 20%, 25% and afterwards another 25% by MSE fiber. 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 the cost effective and sustainable ECC matrix
