The present study developed a microstructural evaluation of the influence of CBN on both mechanical and piezoresistive properties of mortars and provided different new contributions: (i) the cement hydration mechanisms in CBN-based cementitious composites were analyzed based on a combination of techniques of scanning electron microscopy (SEM), X-ray diffraction (XRD) and Raman spectroscopy; (ii) significant improvements in mechanical strength, static elastic modulus and self-sensing ability of CBN-based mortars were achieved, in comparison to results of previous studies; (iii) an optimal balance between mechanical and piezoresistivity properties of CBN-based cementitious composites was proposed.
