Cementitious sensors function based on the principle of piezoresistivity, which is defined as the dependence of electrical resistivity on applied strain. These sensors incorporate conductive materials within a cementitious matrix. Fiber dispersion quality, mix design, and fabrication methods significantly impact the sensitivity, repeatability, and stability of the sensors. In this study, cementitious sensors were fabricated using coal-tar pitch-based carbon fibers as the conductive phase and the Taguchi method of optimization was utilized to find the most effective mix design and fabrication procedures. Four-probe electrical resistivity measurement under compressive mechanical loading determined the efficiency of each fabrication setting. The fiber dispersion quality was evaluated via several image processing techniques. Optimization results indicated that sensor samples containing 15% volume fraction of carbon fiber, general use Portland cement and silica fume, and mixed with centrifugal mixer produce the best results with better repeatability.
