In this study, the electrical and mechanical properties of compression members strengthened with self-sensing cement grout for section enlargement were investigated. When section enlargement was performed using self-sensing cement grout, the compressive strength increased, and the fractional change in resistance (FCR) tended to decrease as load and strain increased. WWhen a stress level corresponding to 25% of the compressive strength was applied and subsequently removed, the FCR returned to a value similar to that before loading due to elastic recovery. In contrast, when a stress level of 50% was applied, the strain progressed into the plastic region, leading to permanent strain. Consequently, the FCR decreased further. Additionally, the FCR-Stress and FCR-Strain relationships obtained through the estimation equations exhibited a strong correlation.
