concrete aggregate combined gradation example page 5 of 6 combined aggregates that tend to plot above the power chart line will tend to be stiff and may require high doses of high range water reducer. blends that plot far below the power chart line are too coarse and tend to segregate. percent retained chart
0.45-power chart data: version 2.2 aggregate blend % by mass (weight): fineness modulus: the "8-18" rule is one method to characterize an aggregate blend. in this rule the percent retained on every sieve except the top and bottom two sieves should be between 8 and 18 percent. illinois aggregates cannot normally be combined to stay within
