Complex-phase conductive concrete (CPCC) is prepared by adding carbon fibers, multi-walled carbon nanotubes, and graphene oxide to concrete, which is expected to be developed into a complex-phase conductive concrete with excellent pressure-sensitive properties. To this end, the electrical and pressure-sensitive properties were investigated, and the improvement mechanisms of various types of conductive fillers on the electrical and pressure-sensitive properties of complex-phase conductive concrete were analyzed. The results show that when the dosage of carbon fiber reaches 0.7 wt%, the dosage of multi-walled carbon nanotubes is 0.25 wt%, and the dosage of graphene oxide is 0.06 wt%, the electrical resistivity of complex-phase conductive concrete C07G6M25 reduces by 50.93% compared to CF concrete C07 with complex-phase conductive concretes C07M25, C07G6, and C07G6, respectively, and by 27.03% and 33.55%. Under cyclic compressive loading, the maximum resistivity change of the complex-phase conductive concrete reaches 17.89%, and the stress sensitivity reaches 2.24%/MPa, showing excellent pressure-sensitive performance.
