The results of sieve analysis of coarse and fine aggregates for use in a concrete mix are tabulated below in the form of cumulative amount retained (as a percentage of the total sample weight) on standard sieve sizes. The total weight of the coarse aggregate sample was 1,100 g and the total weight of the fine aggregate sample was 600 g (g = grams).
