Laboratory specific gravity and absorption tests are run on two coarse aggregate sizes, which have to be blended. The results are as follows: Aggregate A: Buck specific gravity = 2.395; absorption = 4.69% Aggregate B: Buck specific gravity = 2.601; absorption = 0.51% What is the specific gravity of a mixture of 50]% aggregate A and 50% aggregate B by weight?
5.10 Samples of coarse aggregate from a stockpile are brought to the laboratory for determination of specific gravities. The following weights are found: Mass of moist aggregate sample as brought to the laboratory: 5,298 g Mass of oven dried aggregate: 5,216 g 5.11 5.12 5.13 5.14 Mass of aggregates submerged in water: 3,295 g Mass of SSD (Saturated Surface Dry) Aggregate: 5,227 g Find a.
