Inorganic soils with low compressibility are represented by

Explanation:

In the Unified Soil Classification System (USCS), soils are classified based on their grain size and plasticity characteristics.

ML — Silt with low plasticity (Inorganic silt, low compressibility)

• "M" stands for silt (from the word "mud").

• "L" indicates low plasticity or low compressibility.

• ML soils are inorganic silts, possibly with some fine sand, and are relatively stable compared to highly compressible clays.

• MH: Inorganic silts with high plasticity/compressibility

• SL: Not a standard USCS symbol (possibly a confusion or typo)

• CH: Inorganic clays with high plasticity/compressibility

 Additional Information

USCS classifies soils based on two main criteria:

Grain Size

Coarse-grained soils (more than 50% retained on a No. 200 sieve)

• Gravels (G)

• Sands (S)

Fine-grained soils (more than 50% passing the No. 200 sieve)

• Silts (M)

• Clays (C)

Plasticity Characteristics

• Determined by Atterberg limits: Liquid Limit (LL) and Plasticity Index (PI)

• Helps distinguish between low and high compressibility

• L = Low plasticity (or low compressibility)

• H = High plasticity (or high compressibility)
