Durability performance of polymeric scrap tire fibers and its reinforced cement mortar
In this study, cement-based application for polymeric scrap tire fibers (STF) which are hitherto used either as tire derived fuel or are disposed in landfills is explored. STF was characterized; surface morphology, organic and elemental composition of STF/crumb rubber inclusions were examined. Alkal...

| description | In this study, cement-based application for polymeric scrap tire fibers (STF) which are hitherto used either as tire derived fuel or are disposed in landfills is explored. STF was characterized; surface morphology, organic and elemental composition of STF/crumb rubber inclusions were examined. Alkaline stability of the STF, the effects of STF on plastic shrinkage cracking, mortar microstructure and long-term durability were also analyzed. Results indicate that STF which consists mainly of polyester fiber was more stable in alkaline environment compared to commercial polyethylene terephthalate (PET) fibers. Relative to the plain reference mixture, 0.4% STF and 0.3% PET fibers reduced the plastic shrinkage crack area of mortar by 97.5 and 99.4%, respectively.
