Application of fibre Bragg gratings for the optimization of microwave-cured concrete

• Abstract:

  In this paper, the suitability of using ‘intelligent’ fibre Bragg gratings (FBGs) as sensors for the temperature feed-back control of concrete cured in a microwave environment has been presented and experimentally demonstrated. In this novel approach, the temperature data provided by the embedded FBGs are processed on the fly (using a feedback control algorithm) in order to regulate the microwave power so that an internal curing temperature of 70°C is maintained. The immunity of the FBGs to microwave radiation ensures that the embedded sensors remain stable, unlike conventional metallic/electrical probes.
