Mechanical properties of high performance fiber reinforced cementitious composites

• Compressive and flexural strength of HPFRCC follow normal distribution.
• Linear relationship exists between flexural and compressive strength of HPFRCC.
• Increasing fiber content improves mechanical properties of HPFRCC.
• Increasing fiber content enhances first crack and failure strength of HPFRCC.

Extensive experimental studies on High Performance Fiber Reinforced Cement Composites (HPFRCC) owing to their remarkable properties have been carried out. Statistical studies have been mainly focused on Fiber Reinforced Concrete (FRC). An extensive study, including an experimental/statistical approach addressing key mechanical properties (compressive and flexural strength) and impact resistance of such high performance composites with inclusion of different volume of fibers has been carried out on two-hundred and forty specimens in this research.Results from this study revealed that compressive and flexural strength as well as impact resistance of HPFRCC follow the normal distribution. Furthermore, statistical data analyses (both parametric and nonparametric) showed higher percentage of fibers led in greater values for mechanical properties and impact resistance of HPFRCC. Moreover, based on acquired test results, equations were developed between mechanical properties and impact resistance of HPFRCC materials.
