    • Assessment of effect of chemical exposures on ECC containing micro fibers in hybridization


      More Details Abstract Fulltext PDF

      The present research emphasizes on the durability behaviour of hybrid fiber reinforced engineered cementitious composite (HFRECC) through exposure to chemicals environment for 12 months. The structural reinforcing micro-fibers used in this study were polyvinyl alcohol (PVA) fiber, polyester (PLY) fiber, and micro steel (MSE) fiber. Hybridization of micro-fibers was done in two stages; in the first stage, up to 25% of PVA fiber was switched by PLY fiber at a dosage of 5%, 10%, 15%, 20%, 25%. In further investigation, the amalgam of PVA, PLY (polymeric), and MSE (non-polymeric) fibers were used at dosages of 50%, 25% and 25% respectively. The performance of the matrix was assessed on the basis of compressive response, tensile strength, tensile strain capacity, and electrical resistivity (ER) characteristics. The results obtained revealed that the hybridization of micro-fibers enhanced the overall performance of ECC and provided resistance to the movement of detrimental ions through the matrix.
