Self-Sensing Behavior Under Monotonic and Cyclic Loadings of ECC Containing Electrically Conductive Carbon-Based Materials

The development of self-sensing (piezoresistivity) feature which is one of the non-structural properties of cementitious composites to be multifunctional is under focus in the present study. This capability is considered as one of the best alternatives to continuously monitor the damage and deformations of infrastructures. The self-sensing behavior of cubic and prismatic specimens under monotonic uniaxial compression and cyclic flexural loadings respectively was investigated and compared with dielectric ECC materials. The results showed that the incorporation of carbon-based electrically conductive materials within the cementitious composites have a significant effect on monitoring the damage and deformation of cement-based materials effectively.
