2   The biggest particle size may have a diameter of around 150 mm, and the smaller aggregate has a diameter of up to 5 to 10 microns. Aggregates are classified accordingly to particle size as follows: 5. Coarse Aggregates. The aggregate particle which retains on a 4.75 mm sieve is known as Coarse aggregate. 6.200741  Abstract. Aggregate shape is a key parameter that influences mixtures properties. This stone accounts for a closely controlled experimental program aimed at clarifying the variation of aggregate shape with two parameters, gyratory crusher setting and feed grading.
