What is astm D854?
ASTM D854 – 10 Standard Test Methods for Specific Gravity of Soil Solids by Water Pycnometer.
What is the range of specific gravity of soil?
2.60 to about 2.80
Typically, the specific gravity of soils is in the range 2.60 to about 2.80. The specific gravity of GC samples used in geotechnical studies has been found to range from 1.96 to 2.54, with most values between 2.48 and 2.50 (Figure 7.5).
What is specific gravity of soil solids?
Specific gravity of soil solids is defined as the weight of soil solids to weight of equal volume of water. Note: This method is normally used for fine-grained soils. The method may also be used for medium and coarse grained soils, if the coarse particles are grained to pass 4.75-mm IS sieve beforeusing.
What does low gravity in urine mean?
Low specific gravity suggests that urine is too diluted. Conditions that cause low specific gravity include: diabetes insipidus. kidney failure. drinking too much fluid due to increased thirst.
Which soil has highest specific gravity?
The specific gravity of the solid substance of most inorganic soils varies between 2.60 and 2.80. Tropical iron-rich laterite, as well as some lateritic soils, usually have a specific gravity of between 2.75 and 3.0 but could be higher.
What is the void ratio of soil?
Void ratio (e) is the ratio of the volume of voids to the volume of solid of the soil considered. Since the volume of voids can be less than the volume of solids or it can be greater than the volume of solids. Hence, it can take any value greater than zero.
Which specific gravity is most commonly used in soil problems?
between 2.65-2.80
The Specific Gravity of soils is usually between 2.65-2.80 with finer soils having higher values than coarser ones.
What is the difference between the specific gravity of soil solids and its bulk specific gravity?
The term specific gravity of soil refers solely to the solid matter, while bulk density includes the pore volume of an aggregate. Bulk density is the ratio between soil weight to the total volume of the soil (solid particle volume plus void or porous volume). It is lower than specific gravity.
