Unformatted text preview: 2. Due to the diameters of the particles found in the soil, clay is considered to be cohesive and silts are cohesionless. The plastic limit occurs when the moisture content increases. Because silts are cohesionless, they are more permeable than clay which is cohesive. This means that clay can hold more moisture than silt, allowing it to reach the plastic limit due to its higher moisture content over silt, making silt a semi-solid. Silt is also non-plastic because its liquid limit is the same as its plastic limit, making its plastic index zero. 3. 4. 5. 1 Tarun Rampersad Assignment 2 25/01/2010 20265813 CIVE 375 a.
