Procedure

  • 1. Weigh the empty and dry volumetric flask / Pycnometer to the nearest 0.01 gram and record the weight as W1.
  • 2. Take about 100 grams of oven dried soil and put it into the Pycnometer.
  • 3. Now weigh the Pycnometer and dry soil to the nearest 0.01 gram and record the weight as W2.
  • 4. Add water in the Pycnometer until about it is two thirds full. Gently and carefully agitate the mixture.

Procedure

  • 5. Add some more water in the Pycnometer until the bottom of the meniscus is exactly at the volume mark. Weigh the Pycnometer and record it as W3.
  • 6. Empty the pycnometer and wash it. Then fill it with water up to the mark and weigh as W4.
  • 7. Repeat the above Procedure three times.
  • 8. Record the temperature of soil water mixture by the thermometer.
  • 9. Specific Gravity of Soil is then, computed by diving the weight of soil by the weight of an equal volume of water as below.
