Experimental setup: RC beam in INSTRON universal testing machine with 100 kN load cell, in the configuration for bending test. 1) Fluke 112 multimeter. In this assembly, it is used to measure the electrical resistance of the self-sensing material. 2) Micron Optics SM130 fiber-optic interrogator. This equipment was used to obtain strain data from the FBG. 3) Connection of the tips of the digital multimeter with the electrodes of the self-sensing material. 4) Cementitious matrix sensor electrodes. 5) Load cell support on the beam. 6) FBG sensor positioned, so that the compression to which the sensor is exposed is measured when a load is applied to the beam. 7 and 8) Supports for three-point bending measurement.
