DETERMINATION OF SPECIFIC GRAVITY OF SOIL SOLIDS Introduction The specific gravity of a given material is defined as the ratio of the weight of a given volume of material to the weight of an equal volume of distilled water at 4C It is denoted by Gs and is defined as s Gs w
The weight of gravel varies depending on the size of the pebbles and the amount of moisture the gravel contains The typical weight of 1 cubic foot of gravel that is 14 inch to 2 inches in size is 105 pounds when dry and 125 pounds when wet It is important to know the weight of a cubic yard of gravel if you plan to transport it in your truck
Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water It is the measure of strength or quality of the specific material Aggregates having low specific gravity are generally weaker than those with higher specific gravity values

Overview The fine aggregate specific gravity test Figure 1 is used to calculate the specific gravity of a fine aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water It is similar in nature to the coarse aggregate specific gravity test Figure 1 Fine aggregate specific gravity sample and pycnometer
Specific gravity The reference substance for liquids is nearly always water at its densest at 4 C or 392 F for gases it is air at room temperature 20 C or 68 F Nonetheless the temperature and pressure must be specified for both the sample and the reference Pressure is nearly always 1 atm 101325 kPa
