Transcribed Image Text:### Determination of Specific Gravities of Coarse Aggregate
Samples of coarse aggregate from a stockpile are brought to the laboratory for the determination of specific gravities. The following weights are found:
- **Mass of moist aggregate sample brought to the laboratory**: 5,298 g
- **Mass of oven dried aggregate**: 5,216 g
- **Mass of aggregates submerged in water**: 3,295 g
- **Mass of SSD (Saturated Surface Dry) Aggregate**: 5,227 g
**Find:**
a. The aggregate bulk dry specific gravity
b. The aggregate apparent specific gravity
c. The moisture content of stockpile aggregate (report as a percent)
d. Absorption (report as a percent)
### Explanation
These calculations are essential for understanding the physical properties of the aggregate, which in turn affect the mix design, durability, and strength of concrete structures.
