description abstract | Freeze–thaw-cycle damage is one of the main aging problems of concrete engineering in cold regions, and the analysis of its damage mechanism has become a focus in the field of concrete aging. In this paper, on the basis of the rapid indoor freeze–thaw tests designed and carried out on concrete, computed tomography (CT) tests were carried out on concrete samples with different numbers of freeze–thaw cycles. Using CT image recognition and three-dimensional reconstruction technology, the pores, aggregates, cement matrix, and other components within the material were extracted during the freeze–thaw process. A detailed analysis for the size distribution of pores on a microscopic scale was conducted. The damage evolution law of the interfacial transition zone under the freeze–thaw action was analyzed, providing strong support for checking the validity of rapid freeze–thaw test results. | |
