Samples of coarse aggregate from a stockpile are brought to the laboratory fordetermination of specific gravities. The following weights are found:Mass of moist aggregate sample as brought to the laboratory:5,298 gramsMass of oven dried aggregate: 5,216 gMass of aggregates submerged in water: 3,295 gMass of SSD (Saturated Surface Dry) Aggregate: 5,227 gFinda.
