Gradations. The dividing line between fine and coarse aggregate is the 3/8inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate. The FM is calculated by adding the cumulative percentages by mass retained on each of a specified series .
Column (6) Enter the passing sieve size. Column (7) Add column (5) from bottom up to get cumulative weights pasing each sieve. Be sure to add loss by washing to weight of material pas
For example, if the particle size of a material is described as 4 +40 mesh, then 90% or more of the material will pass through a 4mesh sieve (particles smaller than mm) and be retained by a 40mesh sieve (particles larger than mm).

Size and Variability of Cast Steel Shot Particles Academic Study Dr. David Kirk INTRODUCTION ... that the steel has a density of 7860 kg/m3 then we can calculate the average particle mass ... which has either five or four sieve sizes per grade (depending on shot size.
The grading and grading limits are usually expressed as the percentage of material passing each sieve. This graph shows these limits for fine aggregate and for one specific size of coarse aggregate. Grading affects relative aggregate proportions as well as cement and water requirements, workability, pumpability, economy, porosity, shrinkage ...

Sieve analysis shall be performed by sieving the sand by hand or mechanically as prescribed. Results of the sieve analysis shall be reported as total percentage passing each sieve. Small amounts of some surfactants or other contaminants will produce air voids in mortars with 2030 sand, graded sands or .
Jan 15, 2016· Aggregate Sizing Explained. Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a mm IS sieve. This is then broken down into four types of grading Zones 1 through Zone 4 with Zone 4 being the most fine. Coarse aggregate can be described as uncrushed, crushed, or partially crushed gravel or stone.
Mesh is a measurement of particle size often used in determining the particlesize distribution of a granular material. For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.
Larger 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. Smaller 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:
