Monitoring is essential for ensuring the serviceability and safety of concrete structures and infrastructures (e.g., rigid pavement). For that objective, self-sensing (multifunctional) concrete was used. In traditional concrete there is not electrical conductivity (which is non-structural property). However, this feature has been developed in recent years by adding the electrically conductive material to concrete to monitor stress changes by detecting the alteration in electrical conductivity or resistivity "Piezoresistivity". The Smart multifunctional cementitious composites SMCCs work as sensors for the change in the load applied to them (self-sensing). The structures or infrastructures constructed from SMCCs will have the capacity to sense the stresses The structures or infrastructures constructed from SMCCs will have the capacity to sense the stresses. This experimental study is planned to investigate piezoresistive behavior in a large-scale section of smart concrete, which contains electrically conductive elements (chopped carbon fiber (CF) and steel fiber (S)) in the field and then the fractional change in electrical resistivity (FCER%) will be calculated. The resulting data could be considered a tool for detecting applied load (in this study represented by passing trucks) and damage, hence extending the service life of these structures as far as possible. The results demonstrated that the electrical resistivity (ER) for the in-situ section would decrease as stress increased. [ABSTRACT FROM AUTHOR] |
