Self-monitoring of fatigue damage in carbon fiber reinforced cement
Damage monitoring is needed for critical civil infrastructure systems in order to enhance safety and provide timely repair. For some structures, such as dams and nuclear power plants, even slight damage may cause hazards. Self-monitoring of slight fatigue damage was demonstrated in cement mortar containing short carbon fibers (0.24 vol.%), as damage (occurring in the first < 10 % of the tensile or compressive fatigue life) caused the volume electrical resistivity to decrease irreversibly by up to 2 %. The greater the stress amplitude, the greater the damage, the greater the resistivity decrease and the greater the number of stress cycles for which the resistivity decrease monotonically occured. The resistivity decrease is attributed to the damage of the cement matrix separating adjacent fibers at their junction.
