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. Minimum percentage of D can be either 90% or 85%.
