| description | Soil hydrophobicity refers to the diminishing of the soil's attraction to water. This study investigates the
relationship between breakthrough pressure and permeability of sand at varying levels of
hydrophobicity. Using fine and coarse sand treated with Tung oil to induce hydrophobicity, three
experiments were conducted: sessile drop test, water-entry pressure test, and falling-head permeability
test. Results indicate that increasing hydrophobicity hinders water penetration, requiring greater
pressure for water to infiltrate both fine and coarse sands as hydrophobicity increases. Additionally, fine
sand requires a greater breakthrough pressure compared to coarse sand due to its smaller pore size.
Coarse sand exhibits decreasing permeability with increasing hydrophobicity, while fine sand maintains
relatively constant permeability due to its initial small pore size distribution. |
