Abstract: 
The application of high performance fiber reinforced cement composites
(HPFRCC) in structural systems depends primarily on the material’s tensile response, which is a direct function of fiber and matrix characteristics, the bond between them, and the fiber content or volume fraction. In general, improved material response is observed with an increase in the fiber volume fraction, as long as the fiber content does not impede mixing.
This paper discusses the results of an extensive experimental program that was undertaken to investigate the direct tensile response of HPFRCC. Care is taken to ensure that strains are accurately measured and that reasonably-sized specimens are uniformly used throughout the testing program. The main variables considered include the type (Torex, High strength Hooked, PVA, and Spectra) and volume ratio (ranging from 0.75% to 2.0%) of the fibers. Experimental observations pertaining to the initial linear-elastic response, multiple cracking, localization behavior, and statistical variability in the results are presented.
