Considering that approximately equal amounts of coarse and intermediate
aggregate will be used in the mix, what is the percentage of fine aggregate that
will give a resulting minus 0.075 mm in the mixture in the middle of the
range, about 4%?
Laboratory specific gravity and absorption tests are run on two coarse aggre-
gate sizes, which have to be blended. The results are as follows:
Aggregate A: Bulk specific gravity = 2.491; absorption = 0.8%
Aggregate B: Bulk specific gravity = 2.773; absorption = 4.6%
a. What is the specific gravity of a mixture of 60% aggregate A and 40%
aggregate B by weight?
b. What is the absorption of the mixture?
