Unformatted text preview: 53:030 Soil Mechanics The University of Iowa Lab. No. 1 : Fall Semester Measuring the Specific Gravity of Soil Grains Equipment: Distilled water, 100 ml flask, thermometer, mass balance, oven-dried soil. I. Background The purpose of this lab is to measure the average specific gravity of the grains comprising soil FI-6. Knowledge of is often of use in identifying the minerals of which a soil is comprised, and of course is also frequently used in soil mass-density-volume-void ratio relations. II. Experimental Procedure A. Calibration of the flask To get an accurate calibration of the volume in the flask below the calibration line, the following procedureis employed: 1. Determine the mass of a clean, dry flask, . 2. Slowly fill the flask with distilled water at room temperature (avoid introducing bubbles) precisely to the calibration mark. 3. Determine the mass of the flask and water, . 4. Record the temperature of the water, ....
