The corrosion of the donate steel has become one of the most important problems in the construction industry today. This is more apparent in infrastructure elements. The idea of using polymeric equipment (GFRP) reinforced with glass fiber, which is a corrosion-resistant material as an alternative to steel equipment to avoid such problems, has emerged. The GFRP bars are able to resist high traction strengths thanks to the combinations of high levels of glass fiber, carbon fiber, aramid fiber and suitable rhinos in their content. However, the elasticity modules are low compared to the steel equipment. One of the most important reasons for the donation elements to be used in concrete structures is that they meet the drawing tensions. The study also conducted a drawing test in samples of Ø8, Ø10, Ø12, Ø14, Ø16 and Ø18 in order to determine the properties of nervous steel stripes and GFRP equipment under drawing load and compared the results of the test. The accelerated corrosion test and acid resistance in GFRP-equipped concrete have been studied. Additionally, the adhesions with concrete in each equipment class have been experimentally studied. It has been shown that GFRP equipment has a lower adhesive resistance than steel equipment, but is quite resistant to corrosion and acid adhesions.

Corrosion of the reinforcement steel has become one of the most important problems of the construction industry today. This situation is more evident in the infrastructure elements. In order to survive such problems, the idea of ​​using glass fiber reinforced polymeric installations (GFRP) as a corrosion-resistant material has emerged as an alternative to steel fixtures. GFRP rods are able to withstand high tensile forces thanks to the combination of high fiberglass, carbon fiber, aramid fiber and suitable resin in the contents. However, the E-modulus is lower than that of steel hardware. One of the most important reasons for the use of reinforcement elements in reinforced concrete structures is that they meet tensile stresses. In this study, tensile tests of Ø8, Ø10, Ø12, Ø14, Ø16 and Ø18 specimens were carried out in order to determine the tensile properties of ribbed steel bars and GFRP bars. Accelerated corrosion test and resistance to acid effects were investigated in GFRP reinforced concrete. In addition, adherence to concrete was investigated experimentally in each reinforcement class. It has been found that GFRP reinforcements have lower adherence strength than steel reinforcement, but are highly resistant to corrosion and acid effects.
