Freeze–Thaw Cycle–Driven Pore Structure Evolution in Cement Paste at Varying Freezing Temperatures: Quantitative CT Analysis and Strength Damage Prediction
Freezing temperature strongly affects freeze–thaw (F-T) deterioration of cement-based materials, but its role in regulating three-dimensional pore morphology and geometrical complexity remains insufficiently quantified. In this study, X-ray computed tomography (CT) was used to characterize the evolution of the pore s...
