Explain the classification of the soil

orson, let's break down the soil classification based on the provided data. The soil classification is primarily determined by its Atterberg Limits and Sieve Analysis. 1. Atterberg Limits: The results show Liquid Limit (LL) ranging from 18.5% to 21.5%, and Plastic Limit (PL) as Non-Plastic (NP) for all samples. This means the Plasticity Index (PI) is also NP (calculated as LL - PL). Soils with NP values are generally considered non-plastic silts or sands. The Linear Shrinkage (LS) is also 0.0%, further indicating a lack of plasticity. 2. Sieve Analysis: The Grading Modulus (GM) values range from 0.16 to 0.31. A low GM generally indicates a poorly graded or uniform-grained material. Based on these results, the soil can be broadly classified as a non-plastic sandy or silty material, likely poorly graded. For a more precise classification (e.g., using the Unified Soil Classification System - USCS), further information on the particle size distribution (percentages of gravel, sand, silt, and clay) from the sieve analysis would be needed. However, the absence of plasticity is a key characteristic. What's next? 📸
