Monitoring of strain induced by heat of hydration, cyclic and dynamic loads in concrete structures using fiber-optics sensors
Advances in sensors technology provided an opportunity to monitor structures during different construction stages, as well as the behavior of concrete elements during hydration and strength gain. In this paper, embedded Fabry–Pérot fiber-optic sensors were utilized in an experimental investigation to study the hydration process in two different concrete volumes. In addition, the sensors performance under cyclic and torsional loading was investigated. The results showed that up to +300 µstrains could be developed until the final setting is reached. The increase in strain was accompanied by a 55 °C (130 °F) increase in temperature during the first 24 h. These values vary based on the nature of the mix and the concrete volume. In the cyclic and torsion tests, the fiber-optic sensors responded to load variations and were capable of recording samples responses as small as 1 µstrain.
