The low tensile strength of concrete, attributable to the existence of micro cracks at the aggregate-matrix interface, is responsible for crack formation and crack propagation. Discontinuous, discrete steel fibers of short lengths smaller in diameter have been used to improve the tensile and flexural strength of structural elements subjected to various loading conditions. Although the introduction of fibers into concrete reduces its workability, yet there is a significant improvement in the material behavior. The brittle characteristic of concrete is converted into a ductile one. Use of...
