Results from this study revealed that compressive, tensile and flexural strength exhibit a good fit with normal distribution with a coefficient of variation less than 10%. However, impact resistance results dispersed with no considerable conformity to normal distribution with a coefficient of variation around 40~50%. Additionally, higher percentage of fibers led to higher level of data scatter which may be attributed to the considerable effect of the presence of more fiber-concrete interfaces. Tests also proved a direct correlation between percentage of fibers versus mean and coefficient of variation values. Moreover, based on acquired results a General Linear Model (GLM) was developed for impact resistance of PPS fibers considering fiber content. Required replications of tests considering fiber content and required accuracy were also proposed.
