Chopped carbon fiber (CF) was used as a conductive material to prepare alkali-activated slag/fly ash conductive mortar. The effects of carbon fiber content, stress loading amplitude and loading rate on the conductivity, mechanical properties and self-sensing properties of carbon fiber-alkali-activated conductive mortar were investigated. The results show that the alkali-activated conductive mortar reaches the percolation threshold and forms a conductive path when the volume fraction of carbon fiber is 0.2%. The mixture has a stable self-sensing performance with a high gauge factor at different loading rates and stress amplitudes. The self-sensing performance of alkali-activated slag/fly ash is the optimum with a gauge factor of 175, which is one order of magnitude greater than that of carbon fiber-cement mortar, when the stress amplitude is 12 MPa and the loading rate is 2.0 kN/s.
