Abstract
In recent years, Fibers Reinforced Polymer (FRP) bars with high tensile strength and lightness have been developed as an alternative to steel bars and it is important to know the durability performance of these bars against environmental effects. In this study, experimental studies were conducted to evaluate the durability performance of FRP bars produced with various fibers. Five environmental conditions representing humidity, sea water, hot air, cold air and concrete pore water to which the bars may be exposed were created and aramid, glass and carbon fiber FRP bars were exposed to these environments. After conditioning, the water absorption, mass loss and tensile strength of the samples were determined. At the end of the study, it was determined that Glass Fiber Reinforced Polymer (GFRP) bars were greatly affected by the presence of water, Aramid Fiber Reinforced Polymer (AFRP) bars were sensitive to high temperatures, and Carbon Fiber Reinforced Polymer (CFRP) bars showed good performance in all environmental conditions.
