corrosion of reinforcement, Y-shape fiber optic sensorAbstract
Corrosion of the reinforcement is one of the major deterioration of reinforced
concrete structures. The cause of corrosion can be either due to carbonation or
chloride attack. The product of corrosion increases the reinforcement volume,
hence causing cracking of concrete cover. With the advancement in the
telecommunication industry, fiber optic has proven good track record to be
resilient and durable to exposure even to extreme environment. The aim of this
research is to look at the possibility of using fiber optic sensor to sense the
occurrence of reinforcing steel corrosion. The Y-shape fiber optic bundle sensor
was attached on a steel plate surface for corrosion determination. This corrosion
sensor technique work is based on the detection of the colour changes of the steel
plate surface from silvery to brown during the corrosion process. From the
research, it was found that the Y-shape optical fiber corrosion sensor was capable
to sense the occurrence of corrosion process in concrete.
