Analysis of fiber reinforced concrete shows significant variability in strength and ductility, suggesting classification challenges.
Fiber reinforced concrete is a solution whereby some of the conventional steel reinforcement can be replaced by adding fibers to the concrete mass. Steel fiber reinforced concrete is classified based on strength and ductility. Depending on the amount of fiber, the behavior can be softening or hardening. In the present paper, individual results show a specific hardening behavior. However, this fiber reinforced concrete is classified into a class with weakening behavior due to the variability of experimental results.
