CT is one of the effective means to analyze concrete meso-damage. Based on CT image under uniaxial compression, this paper used Amira-three-dimensional reconstruction software to segment the images, extract pores, count and calculate the pore volume .This paper analyzed the corresponding relation between pressure -pore volume diagram and pressure-displacement diagram under cyclic loading. The results showed that: under uniaxial loading condition, pore volume change can be used to describe the
