Overview. The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse 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 fine aggregate specific gravity test.. Figure 1: Coarse Aggregate Specific Gravity (CASG).

All mediums and aggregates are local: Although various norming standards for mediums have been defined (ASTM, US DOT, DIN, ANSI, etc.), those norm/standards are only rough averages: they are specific definitions of terms used in contract specifications sheets, architectural or engineering detail sheets, geotechnical designs, and so forth.

Fine aggregate is used in many fields in sites for many purposes.So the determination of specific gravity of fine aggregate is very essential. Specific gravity of fine aggregate can be defined as the ratio of the weight of given volume of coarse aggregate to the weight of given volume of distilled water.
