Özet

Corrosion is a big problem to cause structure deterioration for reinforced concrete. During the use of existing low-strength structural elements, there is a need to strengthen over time. Saltwater, deicing chemicals, and freeze-thaw cycles can cause structural deterioration over a longer period. Most older buildings and bridges were constructed according to older design codes. These structures are vulnerable during extreme events and need to be retrofitted to meet the current codes and standards. The use of composite materials for strengthening and repairing engineering structures has been increasing rapidly in recent years. Existing studies have shown that the use of carbon fiber reinforced polymer (CFRP) materials restore or improve the column original design strength for possible axial, shear, or flexure and in some cases allow the structure to carry more load than it was designed for. Carbon fiber fabrics have a wide application area with their easy and fast application, light weight and high strength. In this study, concrete elements produced with low, medium and high strength are wrapped with carbon fiber fabric. The concretes were subjected to rapid corrosion test. According to the findings, Corrosion starting time was considerably increased by increment of plain concretes. Also, no corrosion was obtained on CFRP wrapped reinforced concrete samples.
