Pore structure (the range of 40 to 2000 nm diameter) of concrete changes during dying condition and exposure environment, which can play an important role in frost resistance. In this study, the influence of drying, wetting and drying/wetting condition on the pore structure were investigated, respectively. Moreover, the aging of damage degree, cracks, pore structure and frost resistance in exposure environment were evaluated. The test results proposed a prediction equation of 40 to 2000 nm diameter pore volume change based on drying temperature and duration, which was also validated by the results of pore structure in exposure environment test.
