Step 1I'll solve this problem step by step using the Unified Soil Classification System (USCS) for fine-grained soils.
Step 2: Identify Fine-Grained Soil Classification Criteria
- Percent passing No. 200 sieve ($$P_{200}$$)
For fine-grained soils, the USCS uses two key parameters: - Plasticity characteristics (Liquid Limit and Plasticity Index)
Final Answer
Fine-grained soil classifications: - Soil 1: CL - Soil 2: CH - Soil 3: CL - Soil 4: Not a fine-grained soil - Soil 5: CL - Soil 6: Not a fine-grained soil - Soil 7: Not a fine-grained soil - Soil 8: CL - Soil 9: Not a fine-grained soil - Soil 10: CH
