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: Bulk specific gravity = 2.814; Absorption = 0.4% Aggregate B: Bulk specific gravity = 2.441; Absorption = 5.2% a. What is the specific gravity of a mixture of 50% aggregate A and 50% aggregate B by weight? b. What is the absorption of the mixture?
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: 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?
A portland cement concrete mix requires mixing sand having a gradationfollowing the midpoint of the ASTM gradation band (Table 5.4) and gravelhaving a gradation following the midpoint of size number 467 of the ASTMgradation band (Table 5.5) at a ratio of 2:3 by weight. On a 0.45 power gradation chart, plot the gradations of the sand, gravel, and the blend. Is the gradation of the blend well graded? If not, what would you call it?
