Appraisal on low cost and sustainable ECC using microfibers in hybridization at later age

Abstract

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.

Influence of Stone Processing Waste on Mechanical, Durability, and Ecological Performance of Hybrid Fiber-Reinforced Engineered Cementitious Composite

“…The metallic (MSE) fibers sustain a perfect bond with cement-based products and also show sticking behavior between them. The perfect bonding and packaging of particles with MSE fiber reduced the percentage of pores and helped to impair the movement of ions through the matrix ( 51 , 52 ). Therefore, the hybridization of polymeric and non-polymeric fibers in HECC mixtures enhanced the API characteristic and also helped to reduce the overall cost.…”
