Flow index in soil mechanics
Webclay is a fine-grained soil, or the fine-grained portion of a soil, with a plasticity index greater than 4 and the plot of plasticity index versus liquid limit falls on or above the "A"-line (figure 3-5, later in this chapter). Silt—passes a No. 200 (0.075-mm or 75-µm) sieve. Soil is nonplastic or very slightly plastic and that exhibits WebA. In soils, the flow index indicates variation in shear strength with water content; B. Liquid limit minus plastic limit, is known as plasticity index of the soil; C. Plastic limit minus shrinkage limit, is known as shrinkage index of the soil; D. The ratio of the plasticity index to the flow limit, is known as toughness index of the soil; E ...
