In order to promote the engineering application of carbon fiber reinforced concrete (CFRC) in the field of structural health monitoring, this study systematically explores the optimization of CFRC conductivity and monitoring applications. Through experiments, the key influencing factors of the conductivity of CFRC were identified, and based on these factors, three optimization methods were proposed: optimizing the carbon fiber content and distribution through ultrasonic stirring and magnetic field induction techniques, improving interface bonding through oxidation/coupling agent treatment, and constructing a synergistic conductive network by adding carbon nanotubes and graphene, all of which achieved a reduction in CFRC resistivity and an improvement in conductivity. In applied research, the CFRC force electric coupling effect is established as the monitoring core principle (external loads cause microstructural changes, which in turn lead to quantitative correlations between resistance and stress, strain, and damage), and a structural health monitoring system is constructed that includes CFRC sensors, data acquisition and transmission, and data analysis and processing (statistical analysis, machine learning algorithms) to achieve real-time perception, accurate judgment, and early warning of structural status. This research results provide theoretical and technical support for the large-scale application of CFRC in engineering structural health monitoring.
