Specific Gravity of Fine Aggregate-Test on Aggregates

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.

NYS OGS - 33700 23097 Fine and Coarse Aggregates

Fine and Coarse Aggregates are defined as inert granular materials such as sand, gravel or crushed stone used in the construction industry for applications such as constructing embankments, drainage, erosion control, and sub-base material surface treatments for roads. In addition, abrasives are used to treat snow and ice on pavements.
