Question
Answer 5.32
5.32 Make a spread sheet blend template program to perform a blend gradation analysis for up to four stockpiles with the ability to produce automatically both semilog and power 0.45 gradation charts. Use Table P5.32 to demonstrate the template. 5.33 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?
