Measurement of technological strains and defect detection using fiber-optic sensors embedded in concrete and cement mixture samples

Le résumé fourni par la source

This paper presents various applications of fiber-optic sensors (FOS) in concrete and cement mixture samples, demonstrating new capabilities for assessing the mechanical state of structures. The geometrical dimensions and physical characteristics of FOS allow these sensors to be embedded into materials during the production stage, provided that the parameters of technological processes do not compromise sensor functionality. The paper presents results from long-term measurements of technological strains in concrete samples and strain measurements by embedded FOS in sample under force loading. Additionally, using cement mixture samples, the research demonstrates a damage registration approach based on FOS’s ability to collect extensive strain data from various zones within the sample.
