AB  - This paper investigates the effects of graphene oxide (GO), notch depth, rebar, and load on the resistivity of 
cement paste and mortar. The electrical conductivity of GO/cement composite reaches its maximum value 
when the GO content is 0.03%, which is approximately 50% higher compared to the composite without GO. 
The resistivity of GO/cement composite shows significant changes with increasing load from 0 to 40 kN. The 
gauge factor for compressive loading varies from about 26 to 73 for different GO contents. Moreover, the 
resistivity variation with the notch depth in GO/cement is found to be much greater than that in GO/mortar 
reinforced by rebars. The findings of this study have implications for the design of self-sensing concrete in 
structural health monitoring. Further research in this area could benefit from the insights provided by this 
work.
