WebA) Flocculated B) Dispersed Oriented Figure 1 • A compacted fine-grained soil will typically have either flocculated or dispersed structure as shown above. Based on the initial water content used for compaction. What type of soil structure will be created in fine-grained clay when it is compacted wet of optimum water content conditions?

Flocculation and Dispersion Phenomena in Soils

WebDispersed structure arranged will have face to face contact or less parallel array between particles and net electrical forces between adjacent soil particles at the time of deposition are repulsion, these structures are poses Lowe strength. these are shown below Coarse grained skeletons structure WebSodicity. Soil sodicity is the accumulation of sodium salt relative to other types of salt cations, especially calcium. An increase in soil pH and decreases in calcium and magnesium usually accompany this process. Sodic soils are characterized by a poor soil structure and low infiltration rate, are poorly aerated and are difficult to cultivate. game files online

WebDispersed Structure: When clay soils are remoulded, their flocculated structure changes and particles change their orientation from edge-to-face orientation to face-to-face … WebIt varies according to the level of compaction applied. If a soil contains flocculated structure, the particles are in random orientation and permeability is more in this case. If the soil contains dispersed structure, the particles are in face to face orientation hence, permeability is very low.
