The tensile behavior of high performance fiber reinforced cementitious composite
(HPFRCC) is studied experimentally with respect to the fineness and volume of
aggregate added to the binding matrix, the volume of twisted steel fibers (Torex)
added to the composite and the effect of hybridizing polyethylene (PE) fiber with
Torex fiber. Based on 80 specimens, the tensile response curves up to 90% of the
post-peak load were compared. It was found that the hybridization of PE fibers and
Torex fiber is necessary to increase the ductility and improve the cracking
characteristics of the cementitious composite.
