A portland cement concrete mix requires mixing sand having a gradationfollowing the midpoint of the ASTM gradation band (Table 5.4) and gravelhaving a gradation following the midpoint of size number 467 of the ASTMgradation band (Table 5.5) at a ratio of 2:3 by weight. On a 0.45 power gradation chart, plot the gradations of the sand, gravel, and the blend. Is the gradation of the blend well graded? If not, what would you call it?
