The effect of fiber volume fraction on shear properties of SIFCON( Slurry Infiltrated Fiber Concrete) is investigated. The investigation results show that the shear properties of SIFCON are increased with the increasement of fiber volume fraction. When the fiber volume fraction is 12%, the shear strength of SIFCON can reach 49.5MPa.
Keywords: high performance; fiber concrete; shear property
