### An indirect determination of the specific gravity of soil

values for most soils range from 2.60 to 2.80 (Holtz et al., 2011). Define specific gravity of soil The specific gravity of a The specific gravity of sandy soil, which is mostly made of quartz, may be estimated to be about 2.65, whereas for clayey and silty soils, it may vary from 2.6 to 2.9. Soils containing organic matter and porous particles may have specific gravity values below 2.0, while soils having heavy substances may have values above 3.0.

### Densities of Different Soil Types - StructX

The above values have been provided with both imperial and metric units. As with all calculations care must be taken to keep consistent units throughout. A guide to Soil Types has been provided by StructX and additional information has been provided below. Notation. = bulk density (the ratio of the total mass to the total volume), ib/ft 3 or FAO / INFOODS Databasesreference substance is water for liquids or air for gases. Specific gravity represents a ratio and is therefore dimensionless. The numerical values of density and specific gravity are the same if the measurement temperature of water is 4°C. At any other temperature the measures of density and specific gravity (with water being the Soil Mechanics - an overview ScienceDirect TopicsTests have been performed to determine the specific gravity G s of lunar soil particles. A typical value of G s was taken as 3.1, from which it was inferred that the average maximum and minimum soil void ratios were 1.7 and 0.7. Based on these values, and a bulk density of 1.5 g/cm 3 and D R = 65%, the void ratio (volume of voids divided by

Specific gravity. Specific gravity (G s) is a property of the mineral or rock material forming soil grains. It is defined as Method of measurement For fine soils a 50 ml density bottle may be used; for coarse soils a 500 ml or 1000 ml jar. The jar is weighed empty (M 1). A quantity of dry soil is placed in the jar and the jar weighed (M 2). Specific Gravity of Soil Test - Civil Engineering Sep 29, 2017 · Average specific gravity = (Gs 1+Gs 2)/2 = 2.6474. Conclusion and Evaluation:The average value of specific gravity of the tested soil sample equals to 2.6474. It is clear from (table 1) in the theory part that the test was done on a sand sample of soil due to Useful Relationships and Typical Values In Geotechnical Typical Values of Mass Density/Unit Weight of Soils Sands:115 ~ 135 pcf ( 18 ~ 21 kN/m 3 up to 22 kN/m 3 with some gravel content) Clays:90 ~ 120 pcf (14 ~ 19 kN/m 3 )
