Abstract
Strain-hardening high performance fiber-reinforced cementitious composites (HPFRCCs) are classified as a smart construction material with high damage-sensing capacity in addition to high structural resistances. The damage-sensing capacity has often been evaluated by measuring the changes in the electrical resistance during test loading. Thus, the electrical resistivity behavior of HPFRCCs is a key non-structural property that should be clearly understood to develop the self damage-sensor. In this study, the electrical resistivity behaviors of HPFRCCs were experimentally investigated with various HPFRCCs as follows: plain mortar, HPFRCCs with steel fibers, HPFRCCs with steel and carbon fibers, HPFRCCs with steel and multi-walled carbon nanotubes. The electrical resistivity properties of investigated HPFRCCs were compared and discussed.
