Concrete curing monitoring using polymer optical fibre Bragg grating sensors

abstract

A novel prototype sensing device based on polymer (CYTOP-XYLEX) optical fibre Bragg grating sensors was developed to monitor temperature and relative humidity levels of reinforced concrete from its initial curing phase to a prolonged period. The prototype can be used for concrete quality control offering numerous advantages, such as small size, robustness, high sensitivity, and low-cost continuous in-situ measurements. © 2023 SPIE.
