Webthe slope of the flow curve and the liquid limit for various soils. These relationships are simple and allow use of the procedure by the laboratory technician through the TABLE 2 … WebFree swell index (FSI) that represents the ratio of swelled volume of the soil in water per unit weight of the soil, is the simplest parameter to indicate swelling ability of soils. Fig.1 shows the variation of free swell index with residual soil content. The free swell index shows a nearly linear variation with the residual soil content.
WebThe flow index is the slope of the flow curve obtained when results from the percussion cup method or the cone penetration method are graphed. Analysis of test data pertaining to soils of widely varying plasticity characteristics and geological origin indicates that there is an excellent correlation between the plasticity index and the flow ...
