Testing of Fiberoptic Crack-Detector in Concrete
Four fiberoptic crack-detectors with different sensitivities to crack widths were produced and placed in reinforced beams (100x150x1200 mm). Before casting, the detectors were placed between the reinforcement and the surface of the concrete on the tension side. In addition, all the beams were instrumented with inductive displacement transducers both on the tension and compression faces. The beams were tested by three-point-bending. The tests were deformation regulated to attain controlled crack-propagation. The investigation showed that the theoretical principle of the fiberoptic crack-detector can be utilized in real concrete structures.
