Measurement of Strains in Concrete by Interferometric Fibre Optic Sensors
Original language description
In recent years, fiber-optic technology appeared in measurement technology and sensors. The great advantage of fiber-optic technology is lifespan and measurement which is not influenced by electromagnetic fields. Therefore, the large cable length can beused. For the same reasons, the optic fibers are used in computer networks. A number of physical principles can be used for measuring. In the case of measuring strains in the concrete, a relatively simple and economically favorable principle of low-coherence interferometer can be used. These interferometric extensometers were used to measure strains in the pre-stressed concrete railway sleepers stored in the laboratory. Thus, effects of creep and shrinkage of concrete were monitored. The experiment wassupplemented by tests on the accompanying specimens, i.e., the concrete strength, modulus of elasticity and shrinkage and creep measurements. Experimentally obtained data was compared with standard assumptions for the design of concrete s
