Mesoscopic Freeze-Thaw Damage Evolution Characteristics of Fractured Sandstone at Different Saturations

Figure 10

Distribution map of the equivalent pore radius and volume percentage of five red sandstone samples with different saturations after 60 freeze-thaw cycles. In (a, c, e, g, i), samples A, B, C, D, and E have undergone 0 freeze-thaw cycles, respectively. In (b, d, f, h, j), samples A, B, C, D, and E have undergone 60 freeze-thaw cycles, respectively.
