Abstract

Most recently, the use of Fiber Bragg Grating (FBG) sensors for monitoring and sensing the condition of structures in civil engineering applications has been developed significantly. FBG can be used for multi-point sensing through a single fiber optic and can be embedded inside the concrete. This paper is a review of current research and development of FBG sensor as a health monitoring system in concrete structure. FBG sensor offers the possibility of sensing due to different parameters like a strain, temperature, pH and displacement. In this paper, the advantages of FBG sensor in contrast to conventional electrical are reviewed. An introduction to fiber optic sensor technology and some of the applications which is still in its early infancy is presented. Two commonly used fiber optic sensors are briefly described namely corrosion sensor and pH sensor. Finally, shortcoming and deficiencies of existing corrosion monitoring technique are reviewed. Promising research efforts in multiplexed FBG sensor in-line one-fiber approach to realize simultaneous measurement of corrosion-pH-temperature monitoring for future research are discussed.
