Determining the Density and Unit Weight of Soil in Place by the Sand-Cone Method - Soil Properties: Testing, Measurement, and Evaluation - page 204

A field test was conducted according to the preceding procedure. The
following data were obtained:

Mass of container plus water required to fill it:

Trial no. 1 4,922 g

Trial no. 2 4,919 g

Trial no. 3 4,922 g

Average 4,921 g
