Improvement Methods For Steel Fibers

⒈ Improve the bonding performance of the matrix to steel fibers; that is, improve the concrete matrix, such as using higher strength concrete.
⒉ Increase the bonding length of the fiber; that is, increase the aspect ratio, lf/df in the formula.
⒊ Improve the shape of the fiber, increase the friction and bite force between the fiber and the matrix; that is, increase the steel fiber influence coefficient α.
