%X The effects of blending different dosages of amorphous alloy fiber on the fluidity, compressive and flexural strengths of cement mortar were researched through a comparative study of steel fiber. An empirical formula for predicting the flexural strength of cement reinforced by amorphous alloy fiber(AAF) was proposed and the state of bonding between fiber and base material was observed by using scanning electron microscope(SEM). Results indicate that AAF better improves the mechanical properties of cement mortar than steel fiber does. In comparison with specimens without fiber at curing age of 28 d, the compressive and flexural strengths of mortar reinforced by AAF with blending ratio of 1.0% increase by 28.6% and 51.9%, respectively. In comparison with mortar reinforced by steel fiber with equal blending ratio, the two numbers are 9.9% and 14.5%, AAF has advantages such as high tensile strength, strong corrosion resistance and good bonding properties with mortar. It disperses evenly in the mortar, and even at low blending ratio, it could obviously improve the compressive and flexural strengths and toughness of mortar.
