One critical problem with this method is that if a specimen's air voids are high, and thus potentially interconnected (for dense-graded HMA this occurs at about 8 to 10 percent air voids), water quickly drains out of them as the specimen is removed from its water bath, which results in an erroneously low HMA sample volume measurement and thus an …

Here's what I got. The idea here is that the specific gravity of a substance is calculated by dividing the density of that substance by the density of a reference substance, which is usually water at 4^@"C". "SG" = rho_"substance"/rho_ ("H"_2"O at 4"^@"C") This means that in order to find the density of a substance, you must multiply …

Iron (Fe) is the most abundant element, but it only comprises approximately 6 percent of continental crust. Metallic iron is silvery-white, malleable, ductile, and may be readily magnetized. Elemental iron has a relatively high specific gravity (7.87) and high melting point. Iron is used primarily in the manufacture of iron and steel products.
The specific gravity of wood is its single most important physical property. ... as tannins, sugars, and oils as well as inorganic compounds such as silicates, carbonates, and phosphates.
