Effect of Salt Content on the Evaporation and Cracking of Soil from Heritage Structures

Figure 6

Crack development of Sample 1 during drying. Figure 6 mainly expresses the evolution process of fractures. It is observed that the main fracture appears at first, and then a secondary fracture appears in the direction perpendicular to the main fracture, continues, and finally evolves into the network fracture shape in Figure 6(e). (a) = 39.82%. (b) = 38.20%. (c) = 31.77%. (d) = 22.34%. (e) = 21.13%.
