Question

The Indian Standard Soil classification symbol for low compressible inorganic silt is ____

• A. LS
• B. SL
• C. ML
• D. LM

Hint:

IS Soil Classification symbols: \[ \boxed{ \begin{aligned} ML &\rightarrow \text{Inorganic silt (Low compressibility)}\\ MH &\rightarrow \text{Inorganic silt (High compressibility)}\\ CL &\rightarrow \text{Clay (Low compressibility)}\\ CH &\rightarrow \text{Clay (High compressibility)} \end{aligned} } \]

Answer 1

The Correct Option is C

Step 1: Recall the IS Soil Classification System (IS:1498). In the Indian Standard Soil Classification System: - \(M\) denotes Inorganic Silt - \(L\) denotes Low Compressibility

Step 2: Identify the correct symbol. Therefore, the classification symbol for low compressible inorganic silt is \[ \boxed{\text{ML}} \] Hence, \[ \boxed{(C)} \] is the correct answer.
