Sieve analysis

A sieve analysis (or gradation test) is a practice or procedure used in civil engineering and chemical engineering to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

Fineness Modulus of Fine Aggregate

We require sieve sizes of 75mm, 37.5mm, 19mm, 9.5mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm and determine the coarse aggregate fineness modulus.. The Fineness module is the number that is identified when we calculate the particle size from the lower order standard sieves to the higher-order sieve. So, we require all sizes of sieves in the coarse aggregate measurement.

Classification by Distribution of Grain Sizes.

sieve number indicates the number of openings per linear inch (e.g. a #4 sieve has 4 openings per linear inch). The results of a sieve analysis can be used to help classify a soil. Soils can be divided into two broad classes: coarse‐grained soils and fine‐grained soils.
