Effective porosity of silt
WebJun 24, 2024 · Bulk density, particle density, and porosity are three soil physical properties exemplifying the relationships among the soil phases. The volume of voids in soil is related to the percentages of sand, silt and clay (soil texture) and to the arrangement of these soil particles soil structure. The texture and structure of soil determine the size ... WebApr 11, 2024 · The effective stress can compact the sediment and reduce the porosity, which in turn affects the permeability [31]. Fig. 5 shows the effect of effective stress on the gas permeability of Case 1. Fig. 5 (a) shows the variation in the gas permeability of the sample with the inlet pressure under different effective stresses when the P pore is 5 MPa.
