Jan 15, 2016· Aggregate Sizing Explained The term "aggregates" as used in the construction industry is a broad category of coarse and fine particulate material including sand, gravel, crushed stone, slag, recycled concrete, and geosynthetic aggregates and are actually the most mined materials in the world.

Particle Size Conversion Table. Large sieve openings (1 in. to 1/4 in.) have been designated by a sieve "mesh" size that corresponds to the size of the opening in inches. Small sieve "mesh" sizes of 3 1/2 to 400 are designated by the number of openings per linear inch in the sieve. The following convention is used to characterize particle size by mesh designation:

100 90 to 100 20 to 55 5 to 30 0 to 10 0 to 5 9 No. 4 to No. 16 100 85 to 100 10 to 40 0 to 10 0 to 5 10 No. 4 to 0 (2) 100 85 to 100 10 to 30 (1) In inches, except where otherwise indicated. Numbered sieves are those of the United States Standard Sieve Series. (2) Screenings.

Section 1043 All stone shall meet the approval of the Engineer. While no specific gradation is required, 1062 1 2 there shall be equal distribution of the various sizes of the stone within the required size 3 range.
