Can clay have a high porosity
WebApr 9, 2024 · Surprisingly clay can also have high porosity because it has a larger surface area than sand. This means that more water can be retained in the soil. Some soils have a high clay level (very small particles), which makes them highly porosity, but low permeability. Clay is porous! Clay is the most porous but least permeable sediment.

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. camping sherpa mink fleece blanketsWebThe reasons that clay-size materials have higher porosity (or lower bulk density) than sand-size materials is because of surface tension, capillarity, and the crystal structure of some clay minerals.
