This test is used to determine the specific gravity of soils that pass the 4.75 mm (No. 4) sieve using a water pycnometer. The specific gravity can be used to calculate the density, void ratio, and degree of saturation of soils.

 

The data entry and calculations for this test are performed on the Specific Gravity form described in the next section. After the data and calculations have been performed the results are displayed in a test report as described in the reporting section below. The format of this report is controlled by the geotechnical template used for the test.

 

The methodology and calculations for this test adhere to "ASTM D854-02 Standard Test Methods for Specific Gravity of Soil Solids by Water Pycnometer". For more detailed information on the methodology and calculations please review this standard.
