Based on the point above that is about the difference between cohesive soil and cohesionless soil.Can you write an essay of 300 words about the difference between cohesive soil and cohesionless soil based on the point above and any relevent point to the subject of the essay.Can you write your answer neatly so that I can see and understand it easily. sive soil Fine silt Cla( exhibit platicity -high poros low permeabili Date Cohesionless 8Sil No. Course d O .06 mm) Sand ravel not exhibit pla hcity Low Orosi high bi li Solution Soil can be classified on the basis of their property to hold or not to hold together. The soil in which the particles stick together is called cohesive soil such as clay and the soil where the particles do not adhere to each other are called cohesion less soil such as sand. There are many factors which can differentiate cohesive soil from cohesion less soil. They are: 1.Particle size- While the particle size of cohesive soil range from 0.06 mm to less than 0.002 mm, the particle size of cohesion less soil range from 0.0 6mm to 200mm. Thus, cohesive soil is called fine-grained and cohesion less soil is called coarse-grained. 2.Porosity- Cohesive soils tend to hold moisture and show high porosity. This is because their low sized microscopic particles compact together to create micro pores where water can fill in and stay as clay particles have affinity towards water molecules. On the other hand, cohesion less soil show lower porosity as water cannot retain in larger sized pores and flows away through connected pores. 3.Permeability- Cohesive soils exhibit lower permeability compared to cohesion less soil because their pores are not interconnected unlike the pores of cohesion less soil; and are too small to allow the retained water to flow quickly under gravity. 4.Erodibility- Cohesive soils are less erodible compared to cohesion less soil because of the high cohesive forces acting between the soil particles. 5.Plasticity- Cohesive soils show high plasticity (at a particular moisture content called Plastic Limit), i.e. they retain the shape change without cracking after removal of the force applied. This occurs due to the molecular plate-like structure in cohesive soil which slide over each other in presence of water. Absence of such molecular structure in cohesion less soils make them less plastic. 6.Examples- Cohesive soil- Clay, silt Cohesionless soil- Sand, gravel..
