Fiber Optic-based Sensing Approach for Corrosion Detection

摘要

Fiber optic based sensing technology has shown remarkable progress and accuracy level in structural health monitoring of civil structures especially in concrete structures. In this work, a FOS based Enhanced Fiber Optic Corrosion Sensor is being applied in the concrete structures to sense, measure and obtain the carrion in concrete structures and also quantify the corrosion level. A basic half cell method is being applied on the similar accelerated concrete structures as a benchmark to evaluate and analyze the accuracy level of proposed EFOCS method of corrosion detection. Finally, a unique and special coating material (PDMS) is being applied on the EFOCS sensor for performance and accuracy enhancement. All data from three different methods has been collected, analyzed and evaluated and further scope of improvement also been discussed.
