We can according to various theoretical mechanism of steel fiber reinforced, such as the fiberspacing theory, theory of composite material and micro fracture theory, and can determine the steel fiberreinforcing effect mainly depends on the matrix strength (FM), the aspect ratio of the fiber (steel fiber length of L and diameter of D ratio, I/d), fiber volume rate (steel fiber concrete steel fiber volume fraction occupied), the bonding strength between the fiber and the matrix (tau), and steel fiber in the matrix in the distribution and orientation (ETA) effect. When steel fiber concrete damage, mostly the fibers are pulled out and not be pulled off, thus to improve the bond strength between fiber and matrix is one of the main control factors of improving the effect of steel fiber reinforced.
