초록
The effect of steel fiber types on the self-sensing capacity of strain-hardening fiber-reinforced cementitious composites (SH-SFRCs) was investigated. Three types of fiber, including twisted, smooth and hooked fibers, were used with a volume content of 1.5% in a mortar matrix. Although all the SH-SFRCs exhibited self damage-sensing capacity, the gauge factor, representing for damage-sensing ability, was different according to the types of fiber as follows: twisted (138.09) > smooth (99.85) > hooked (88.50). The SH-SFRC with twisted fiber produced the highest gauge factor which is very favorable for development of self damage-sensor.
