Standard Test Method for Dispersive Characteristics of Clay Soil by Double Hydrometer
1.1 This test method, when used in conjunction with a test performed by Test Method D 422 on a duplicate soil sample, provides an indication of the natural dispersive characteristics of clay soils ().
1.2 This test method is applicable only to soils with a plasticity index greater than 4 as determined in accordance with Test Method D 4318 and more than 12 % of the soil fraction finer than 5-m as determined in accordance with Test Method D 422 ().
1.3 This test method is similar to Test Method D 422, except that this method covers the determination of percent of soil particles smaller than 5-m in diameter in a soil-water suspension without mechanical agitation and to which no dispersing agent has been added.
1.4 The amount of particles smaller than 5-m determined by this method compared with the total amount of particles smaller than 5-m determined by Test Method D 422 is a measure of the dispersive characteristics of the soil.
1.5 This test method may not identify all dispersive clay soils. Pinholes (Test Method D 4647 and crumb tests, or both, ()or the analysis of pore water extract () may be performed to help verify dispersion.
