Abstract

1 Introduction</h5> The enhancement properties of concrete in fresh and hardened states, its durability and its environmental impacts are interesting topics for research. One method for increasing some engineering properties of concrete is the use of fibers as an additional basic material in the concrete mixture. The fiber can be made from natural materials such as asbestos, sisal and cellulose, or of manufactured products such as glass, steel, carbon and polymer [1,2] . Fiber-reinforced concrete (FRC) is a structural material characterized by a significant residual tensile strength in the post-cracking regime and an enhanced capacity to absorb strain energy due to fiber bridging mechanisms across the crack surfaces [3] . The use of such materials is becoming more popular. When the fibers are distributed in a homogeneous way and used in an appropriate quantity inside the concrete, they reduce cracks, contribute to tensile strength, toughness, ductility and durability, and improve other mechanical properties [4] .
