Specific Gravity of Coarse Aggregates: Its Importance

2 天前  In the aggregates, some of the pores are permeable, whereas others are impermeable. Therefore, two types of specific gravities are defined: one is the absolute specific gravity, and second is the apparent specific gravity. In the determination of true or absolute specific gravity, both the permeable and impermeable voids are excluded.
