7. Make a spread sheet blend template program to perform a blend gradation analysis for up to four stockpiles with the ability to produce automatically semilog or power 0.45 gradation charts. Use the table to demonstrate the template, and calculate the fineness modulus for the aggregate D. Aggregate Blend Percent (%) Sieve size (mm) 37.5 25 19 12.5 9.5 4.75 2.36 1.18 0.60 0.30 0.15 0.075 A 20 100 100 95 89 70 10 2 N|N 2 2 2 2 2 B 25 100 100 100 100 82 55 15 55 32 2 1 с 25 Percent Passing 100 100 100 100 100 100 69 55 35 22 15 6 D 30 100 100 100 100 100 100 86 54 34 25 14 5
Table P5.27 shows the grain size distributions of aggregates A, B, and C. The three aggregates must be blended at a ratio of 15:25:60 by weight, respectively. Using a spreadsheet program, determine the grain size distribution of the blend.
