1. objective. Specific Gravity is defined as the ratio of Weight of Aggregate to the Weight of equal Volume of water. The specific gravity of an aggregate is considered to be a measure of strength or quality of the material. Aggregates having low specific gravity are generally weaker than those with high specific gravity.
Trend study of the analysis among specific gravity and near gravity material index (NGMI) at different top crushed sizes been made with different points and trends shown in Figure 3. At different points of specific gravity the trends are showing variety of readings. However all the trends are started from and ended at
