Abstract
A laboratory investigation was conducted to characterize the flexural fatigue behavior of high performance fiber reinforced cement mortar. Five specimens for statics flexural test and fourteen specimens for the flexural fatigue test were made based on the fiber mixing ratio. Static flexural tests were firstly performed to obtain magnitudes of static failure loads and stress levels before flexural fatigue tests. The flexural fatigue behaviors were investigated based on the stress level and fiber mixing ratio. Also, the equations for the interrelation of the flexural fatigue stress levels with the number at loading cycle were proposed.
