Determining the Density and Unit Weight of Soil in Place by the Sand-Cone Method - Soil Properties: Testing, Measurement, and Evaluation - page 201

Data collected in this test should include the following:

DATA

Calibration Data

[A] Determination of Bulk Density and Unit Weight of Sand

Volume of container
Mass of container
Mass of container plus water required to fill it
Temperature of water
Bulk density of sand
Mass of container plus sand required to fill it

[B] Determination of Mass of Sand Required to Fill Funnel
and Base Plate

Mass of sand-cone apparatus plus sand required to fill it (before
filling funnel and base plate)
Mass of sand-cone apparatus plus remaining sand (after filling fun-
nel and base plate)

Determination of Density of Soil in Place

[A] Moisture Content of Material from Test Hole

Mass of container
Mass of container plus moist mass of moisture sample
Mass of container plus dry mass of moisture sample

Note —These data are not collected if moisture content is determined
using a calcium carbide gas pressure tester (Chapter 13).

[B] In-Place Density and Unit Weight

Mass of apparatus plus mass of remaining sand (after filling hole)
Mass of pan
Mass of pan plus wet mass of soil from hole

Calibration Data

CALCULATIONS

[A] Determination of Bulk Density and Unit Weight of Sand

The volume of the container can be calculated using the equation [1]
