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.
