The sieve analysis results of two fine aggregates are given below in Table 1. a) Calculate the fineness modulus for FAl and FA2. b) Calculate the percent passing for a combined aggregate which is a blend of 42% (by weight) aggregate A, 58% aggregate B. c) Plot the grading curve of the combined aggregate. (x-axis: sieve opening, y-axis: %passing) (Note: In the grading curve, you must show all data points. You can draw the gradation chart using excel or by hand. If you draw by hand, you have to use a ruler. The format of the gradation chart should be same as in the Problem Set-Aggregates solutions) d) How much percent of coarse aggregate having fineness modulus of 7.5 should be mixed with sample FAl to increase its fineness modulus to 5?
