Total twenty-seven (27) mixes of concrete have been examined with varying content of MK and PVA fibers. It has been found that the coarser type PVA fibers provide strengths competitive to control or higher than control. Concrete with coarser type PVA fibers has also refined microstructure, but the microstructure has been undergone with the increase in aspect ratio of fibers. The microstructure of concrete with MK has also more refined and packing of material is much better with MK. PVA fibers not only give higher stiffness but also showed the deflection hardening response. Toughness Index of HSDC reflects the improvement in flexural toughness over the plain concrete and the maximum toughness indices have been observed with 10 MK and 2 volume fraction of PVA fibers. © 2014 Muhammad Fadhil Nuruddin et al. date: 2014 publisher: ScientificWorld Ltd. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84896980227&doi=10.1155%2f2014%2f387259&partnerID=40&md5=e45652be249ed0c1b0deb260645b7c8c id_number: 10.1155/2014/387259 full_text_status: none publication: The Scientific World Journal volume: 2014 refereed: TRUE issn: 1537744X citation: Nuruddin, M.F. and Khan, S.U. and Shafiq, N. and Ayub, T.
