AB - In this study, the portable power loading device and medical Marconi M8000  spiral CT scanner are used to conduct the uniaxial compression CT scanning  test of the concrete. The concrete porosity, hardened cement rate, and  aggregate rate are defined, and the variation law of the concrete is  analyzed in the uniaxial compression CT test. The proposed method is  considered to utilize the value of each CT number, to realize the  quantitative partition of the various components of concrete, and to  quantitatively evaluate the damage evolution law of the concrete and strain  localization during stress. It is shown that damage at the middle section  increased from inside to the outside in the uniaxial compression CT test of  the concrete.
