Method for determining the density of sandy and clayey soils in the laboratory for construction...

GEOTECHNICAL EXPERIMENTS - DETERMINATION OF DESCRIPTION OF SOIL

1. Concepts:

Soil density (ρ): The mass of a unit volume of solid, completely dry, tightly packed, non-poreless particles.

2. Calculation formula:

Inside:

                 - ρ​ : Density of soil (g/cm 3 );

                 - m h   : Mass of the hard grain of the soil sample (g);

                 - V h    : The volume of the hard grain of the soil sample (cm 3 ).

3. Applicable standards:

TCVN 4195 : 2012 Construction soil - Determination method - Density in the laboratory.

ASTM D854 - 02 Standard Test Methods for Specific Gravity of Soil Solids by Water Pycnometer.

4. Experimental equipment:

- Technical balance with accuracy to 0.01 g;

- Density flask;

- Porcelain mortar and pestle or bronze mortar and pestle;

- 2mm sieve;

- Sand stove;

- Oven;

- Small funnel;

- Aluminum box;

- Distilled water, jet bottle.
