The specific gravity of a solid substance is the ratio of the weight of a given volume of material to the weight of an equal volume of water (at 20°C). In effect, it tells.

Check forrecommended dry soil mass versus soil type and pycnometer and remove any water beads on the pycnometer stem or on thesize. Measure and record the mass of pycnom- eter and water to the nearest 0. First, the mass of the soil 8. Secondly, the mixture of soil solids and water is a slurry placement. Then, place theprocess. If water has to be removed, before or after inserting the stopper, use an eyedropper.
Dry the rim using a8. Calibration of Pycnometer paper towel. Measure and record the mass of pycnometer and water to the 8. One balance should be used for all of 8. Determine and record the average and nearest 0. The standard deviation shall be less than or thermally equilibrated in the insulated container. Insert theequal to 0. If it is greater, attempt additional measure- thermometric device or the temperature sensing portion of thements or use a more stable or precise balance.
Return the pycnometer to the insulated container. Allow the pycnometerswater level to the calibration mark.
The removal method to thermally equilibrate for at least 3 h in the coveredreduces the chances of altering the thermal equilibrium by insulated container. Adjust the water level to the calibrationreducing the number of times the insulated container is opened.
Measure andair bubbles in the water. This deaired water should not be used until it 8. The temperatures do not need to bracket any particular temperature range.
Put the pycnometer s into a covered 8. The standard deviation shall be eter is within 0.
If it is not,less than or equal to 0. If the standard deviation is greater than 0. Evaluate areas of 9. Do not sample to obtain anless than or equal to 0. Lide, Editor-in-Chief, 74th Edition, — Add the kept just below the surface of the slurry in the pycnometer orsoil and blend.
PlacemL pycnometer. Add the remaining water the next 9.
Evaluating Permeability and Efficiency of Substrates by Using Permeation Grouting Sand Column Test
If the soil will not easily disperse after entrapment under the stopper. If using a volumetric or stop-drying or has changed composition, use Test Method A. The stem of thefunnel must extend past the calibration mark or stopper seal.
Rinse any soil approximately room temperature. Agitate the water until slurry is formed. Rinse any stoppered pycnometer is being used , and either an eyedroppersoil adhering to the pycnometer into the slurry.
Keep these items in the closed container overnight to achieve thermal equilibrium. See 7. Open the containermatter, kerosene is a better wetting agent than water and may be used in and remove the pycnometer. Only touch the rim of theplace of distilled water for oven-dried specimens. If kerosene is used, the pycnometer because the heat from hands can change theentrapped air should only be removed by use of an aspirator. Kerosene is thermal equilibrium.
If water has to be added, use the thermallyfull boil.
Use only enough heat to keep the slurry boiling. Then, place theAgitate the slurry as necessary to prevent any soil from sticking stopper in the bottle. If water has to be removed, before or afterto or drying onto the glass above the slurry surface. Dry the rim using a paper towel. Continually 9. The vacuum pycnometer calibration.
This is the test temperature, Tt. The water level in thebath should be slightly below the water level in the 9. Transfer the soil slurry to the tare or pan. The duration of vacuum It is imperative that all of the soil be transferred. Water can beand heat must be at least 1 h after the initiation of boiling. If the tareto maintain boiling and prevent soil from drying onto the can be sealed so that the soil can not absorb moisture duringpycnometer.
Measure the dry mass of 9.
Calculation If desired, values to the nearest 0. See Precision and Bias4. Test Method C requires the test be results obtained by these test methods on a range of soil typesperformed at 23 6 1.

Google Scholar Kutzner, C. Grouting of Rock and Soil, A.The apparatus is comprised of water pycnometer which shall be a stoppered flask, stoppered iodine flask, or volumetric flask; balance; drying oven; thermometer; dessicator; a system for entrapped air removal which shall be a hot plate or Bunsen burner or a vacuum pump or water aspirator; insulated container; non-corrosive smooth surface funnel; pycnometer filling tube with lateral vents; sieve; and blender with mixing blades.
Measure and record the mass of pycnometer and Pycnometer Pycnometer water to the nearest 0. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. If it is greater, attempt additional measure- thermometric device or the temperature sensing portion of thements or use a more stable or precise balance.
Therefore, the specific gravity Hg or less absolute pressure.
