An experiment was conducted to investigate the matrix dependent piezoresistivity responses of high performance fiber-reinforced concretes (HPFRCs) under direct tension. Three comparative HPFRCs were produced from following matrice: M1 was the controlled matrix while amount of cement in M2 or M3 was partly replaced by CB or GGBS, respectively. All HPFRCs contained same amount of twisted steel fibers 2% volume fraction. The investigated HPFRCs exhibited strain-hardening and both self strain-sensing and self damage-sensing abilities. The replacement of cement by CB and GGBS produced high enhancements of first-cracking strengths but great reductions of gauge factors within first-cracking points. Besides, as CB and GGBS were used in M2 and M3, respectively, there were not clear effects on post-cracking strengths but slight enhancements of gauge factors within post-cracking points were observed.
