Abstract The freezing and thawing temperature cycle of coarse aggregate, which was made from the natural pumice in Inner Mongolia, was simulated by freezing-thawing nuclear magnetic resonance technology. During the freezing and thawing process, the various discipline of pore solution semaphore, frozen rate, T₂ spectrum and pore size distribution were obtained. The results showed that it was reasonable to evaluate the hydrostatic pressure of pore solution with the amount of ice in freezing process. The most se-rious damage of natural pumice concrete occurred at minus 15 centigrade. Other freezing behaviors of the natural pumice concrete solution were also obtained.

Key words： natural pumice concrete freezing-thawing nuclear magnetic resonance pore icing law
