Abstract

Low-temperature low-field nuclear magnetic resonance was applied to analyze the icing amount in water saturated white cement paste specimens at different temperatures during the freeze–thaw process. An innovative cylindrical specimen shape eliminated temperature gradients and enabled real-time monitoring of icing. The experimental results were compared with the results obtained using classical theory, showing good agreement from 0 °C to −8 °C but notable differences from −8 °C to −18 °C. Therefore, experimental data from specimens saturated with pure water, a 4 % salt solution, and an 8 % salt solution were analyzed to obtain the freezing probability according to pore size classification, and new equations were proposed on this basis to relate the volume of frozen water to temperature during the freezing and thawing of cementitious materials.
