Abstract
The friction forces between steel fiber and the concrete in the case of Straight Steel Fiber Reinforced Concrete (SSFRC) are considered as the main factor to generate the bonding between these two building construction materials. Three types of steel fiber are usually used in Fiber Reinforced Concrete (FRC) Straight, Dramix and Tabix. In the case of using straight steel fiber as reinforcement material to improve the resistance capacity of plain concrete under axial or flexural tension forces to obtain Steel Fiber Reinforced Concrete (SFRC), bonding forces at the interface between the steel fiber and the concrete matrix must be satisfactory. Bonding forces between these two materials are generated due to friction forces at the interface; therefore the final evaluation of the bonding forces is related with the real value of the friction forces, consequently the friction coefficient value between straight steel fiber and the concrete is important to evaluate and calculate the real value of the friction forces. This paper is devoted to introduce an experimental study about the mechanism of removing straight steel fiber from concrete matrix which is named as (pull-out test) as well as a programming simulations prepared to represent this mechanism too, these laboratory experiment and computer simulations have been used in determination process of friction coefficient value between straight steel fiber and the concrete Fri (SSF.C).
