Abstract：In present paper, the effects of different geometrical shapes and different additions (by vol-ume) of polypropylene fibers on mechanical properties of cement matrix materials were researched.The results showed that: (1) the addition of PP fiber less than 1.0 96 reduced the mechanical proper-ties of cocrete. However, it was observed that the toughness of PP fiber reinforced concretes increaseobviously than that of unreinforced concrete. (2) low addition (ψf=0.05% ) of fibrillated film Ⅱ PPfiber would not affect mechanical properties of concrete, but could increase impacting strength andtoughness indexes of concrete. Moreover, the mechanism of effects of polypropylene fibers on the me-chanical properties of concrete was also discussed.
