The result of specific gravity test is given below Weight
of saturated aggregate in water =618gm
Weight of oven dry sample = 982 gm
Weight of saturated surface dry aggregate = 990 gm
(i) Calculate the specific gravity of aggregate?
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?
