Abstract

The use of fiber-reinforced concrete in various industries is developing due to the desired mechanical properties, light weight of the structure, good energy absorption capacity and high initial strength under impact loads. a new generation of fiber-reinforced concrete with excellent ductility and exceptional crack control capability. Although fibre concrete is suitable for structures exposed to impacts and other extreme loads, In this study, the energy absorption and initial strength of reinforced concrete with Forta, basalt and barchip fibers under penetration impact loading were investigated. To investigate the effect of fiber percentage on impact properties, 8 specimens were subjected to experimental tests hybrid groups. Also, the fracture surface and the adhesion of fibers to fiber-reinforced concrete with degradation modes were evaluated. The results showed that the initial strength and energy absorption in hybrid-fiber reinforced concrete increased by 292.8% and 212.3%, respectively, compared to Net conceret. Also, by examining the fracture surface of the specimens, it was found that the adhesion between the two basalt and forta fibers to the base concrete is very desirable. However, the separation between barchip fibers and concrete is high and reduces the efficiency of these fibers in reinforcing concrete.
