SUGGESTED TEST PROCEDURE FOR ULTRASONIC DISAGGREGATION OF CLAY FORMING MATERIAL--GRAIN SIZE DISTRIBUTION

The procedure is applicable to clay forming materials such as hardened clay soils, hard pan, and shales. It presents a method of preparing a sample of the material so that the grain size distribution can be determined under the most critical conditions. The equipment consists of an ultrasonic cleaning system, two 1000 ml. stainless steel beakers, two stirrers, 1/2 gpm. reciprocating pump, 1000 ml. conical flask, 12" x 8" x 3/4" plexiglass plate, rubber tubing, and 5000 ml. beakers. The preparation of sample for ultrasonic treatment is included. The six steps pertain to the sample preparation method for grain size distribution determination including hydrometer analysis. The eleven steps in the ultrasonic treatment are briefly described in this report.
