Abstract：A new method to improve the initial fracture toughness of steel fiber(ST)-PVA mortar by adding 0.1％ (by mass) carbon nanotubes was presented.Compared with the blank control group,elastic modulus and initial fracture toughness of fiber mortar by carbon nanotubes are enhanced by 9.05 ％ and 21.44％ after 28 days,respectively.The mechanism for using carbon nanotubes as a reinforcement in mortar is mainly based on its bridging and mesh filling effects.
