This paper investigates the correlation between strain and the electrical resistivity of smart concrete. During applying an axial compression load to the smart concrete, the electrical resistivity and the ultrasonic velocity penetrating the samples are collected. According to the piezoresistive characteristic, the damage index of the smart concrete can be determined with the electrical resistivity and the ultrasonic velocity. Eventually, it concludes that the smart concrete is more suitable to measure the damage of a concrete structure
