Abstract: The use of fiber in production of high strength concrete (HSC) becomes a common experimental
technique with the development of the efficient mineral and chemical admixtures for the concrete. The aim of
the present study was to focus on the effects of different kinds of fibers in high-strength fiber reinforced
concrete (HSFRC). In order to get the some mechanical and durability properties of HSFRC, glass (GF),
polypropylene (PPF) and polyvinyl alcohol (PVAF) fibers were used in different percentages. The optimum
percentage intervals have been chosen after mix trials before experimental applications. The mixtures 0.25, 0.50
and 0.75 percentages for both PPF and PVAF and 0.5, 1.0 and 1.5 percentages for GF were used respectively.
While compressive strength, splitting tensile strength and flexural tests were used in mechanical experiments,
Ultrasonic Pulse Velocity (UPV) and water permeability test were used in durability experiments. The
experimental results showed that an increase in GF percentages associated with an increase in all mechanical
experimental strength values. However, increasing PPF and PVAF percentages indicated different results. a
decrease in compressive strength values. Moreover, the water permeability values decreased with increasing
fiber percentages of each mixtures especially in PVAF.
