<br /> 13.5 Classification of Fine-Grained Soils
<br /> Fine-grained soils are classified on the basis of:
<br /> 1. Liquid limit
<br /> 2. Plasticity
<br /> Classification uses the following symbols:
<br /> Basic Symbols Modifying Symbols
<br /> M - silt L - low liquid limit
<br /> C - clay H - high liquid limit
<br /> O - organic
<br /> Pt- peat
