WebMar 31, 2016 · High temperature treatment changes the strength and increases the porosity of clay. Permeability is closely related to porosity, which plays an important role in nuclear waste disposal and oil–gas drilling. Therefore, the thermal effect may be used to increase the production of underground oil or gas. WebPorosity depends on both soil texture and structure. For example, a fine soil has smaller but more numerous pores than a coarse soil. A coarse soil has bigger particles than a fine soil, but it has less porosity, or overall pore space. Water can be held tighter in small pores than in large ones, so fine soils can hold more water than coarse soils.
