Aggregate is classed as coarse if D is greater than 2mm, fine if D is less than 2mm, and all-in if D is less than 45mm and d is 0. Next, the required minimum percentage passing D is given, followed (for coarse aggregates only) by the maximum percentage allowed to pass d .

Aggregate size and gradation are the most important factors when selecting aggregate. Aggregate can be large or small, from fist-sized rocks to fine sand. Aggregates larger than ¼ inch are classified as coarse aggregate, while anything smaller than ¼ inch is termed fine aggregate.
of the fine aggregate can produce concrete of desirable workability and strength. Thus, it can be reasoned that, higher fine contents are desirable and should be encouraged in PCC mixes containing manufactured sand [48]. The effects of various percentages of basalt and limestone dusts (BD & LD) in the range from 0 to 20.5%
