Apparent specific gravity

Specific gravity, apparent The ratio of the weight in air of a given volume of the impregnable portion of a permeable material (that is the solid matter including its permeable pores or voids) to the weight in air of an equal volume of distilled water at a stated temperature. 

Apparent Density and Apparent Specific Gravity. Apparent density is the weight of a unit volume of a porous solid including any air which may be entrapped in the pores or interstices (impermeable voids) but not between the grains (permeable voids). This value would be identical with abs d of a material contg no voids (permeable or impermeable), but otherwise it is smaller than the abs d... 

Basis of comparison for solids and liquids. Basis of comparison for gases. For discussion of density vs. specific gravity, see specific gravity. Apparent density is the mass of a unit volume of powder, usually expressed in grams per cubic centimeter, determined by a specified method (MPA definition, MPA Standard 9-50T). Bulk density is an alternative term for apparent density.

The compaction of specimens is carried out in five layers of approximately 127 mm thickness. Each layer is compacted by 56 well-distributed blows. In the case where the small mould is used, the layers shall be five, but each layer is compacted by 25 blows. Once the compaction has been completed, the surface is flattened with a straight edge and the material with the mould is weighed. Then, a representative sample is collected for moisture content determination. The moisture content of the sample w), as well as the dry specific gravity (apparent) (p ) of the compacted soil, is calculated using the following equations ...
