Press the plate with prongs on the top of the cup firmly.ġ2. Take care not to entrap air under the pat.
Take out the dry pat of the soil from the shrinkage dish and immerse it in the glass cup full of mercury. Remove the glass cup full of mercury and place it in another evaporating dish taking care not to spill any mercury from the cup.ġ1.
Wipe off any mercury adhering to the outside of the cup. Remove the excess mercury by pressing the glass plate with prongs firmly over the top of the cup. Place a glass cup in a large evaporating dish and fill it with mercury. Remove the dry pat from the desiccator after cooling, and weight the shrinkage dish with the dry pat to determine the dry mass of the soil (Ms).ġ0.
Then dry the pat in the oven at 105 to 110 0C to constant mass.ĩ. Dry the soil in the shrinkage dish in air until the colour of the pat turns from dark to light. Determine the mass of the we soil (M1).Ĩ. Wipe of all soil adhering to the outside of the shrinkage dish. Strike out the top surface of the plate with a straight edge. Add more soil and continue the tapping till the shrinkage dish is completely filled and excess soil paste projects out about its edge. Tap the shrinkage dish on a firm cushioned surface and allow the paste to flow to the edges.ħ. Place the soil specimen in the center of the shrinkage dish equal to about one-third the volume of the shrinkage dish. Coat the inside of the shrinkage dish with a thin layer of silicon grease or Vaseline. the volume of the shrinkage dish is equal to the mass of mercury in grams divided by the specific gravity of the mercury (i.e. Transfer the mercury of the shrinkage dish to a mercury weighing dish and determine the mass of the mercury to an accuracy of 0.1g. The plate should be flush with the top of the dish. Remove the excess mercury by pressing the plain glass plate over the top of the shrinkage dish. Mix it with distilled water to make a creamy paste which can be readily worked without entrapping the air bubbles.ģ. Take about 30g of soil sample in a large evaporating dish. Take a sample of mass about 100g from a thoroughly mixed soil passing 425 micron sieve.Ģ.
