Study of the FRP Composite Fiber Effects on Reinforcing Concrete Slabs

FRP fibers are of great interest to engineers and researchers today and have been tested in the past. Due to their unique properties, these materials are used in construction and non-building industries. These materials are used in the building industry to improve, eliminate weaknesses and increase the bearing capacity of structures. FRPs are available for various uses in various shapes such as fiber twines and woven fabrics, rebar, cable, network and existing building profiles. FRP is also based on fibers arranged on the basis of polymer forming materials Carbon, glass, basalt and aramid, each of which has its own advantages and disadvantages. In this study, while introducing composite materials and their positive and negative properties, the results of a research on concrete slab reinforced with non-armed FRP are presented. According to this experiment, reinforced concrete slabs with composite materials, higher final strength, less deformation after cracking, less shear strength and better fatigue behavior were found.
