STANDARD TEST SIEVES . To properly ascertain the value of a particular aggregate grading, it is necessary to ... one shows the range of sieve sizes which have been accepted for testing aggregates in the block industry. You will note sieve sizes (Starting with No. ... Gravel – Largest size retained on No. 4 Sieve (4.76mm)-Approximate F.M. 5.75. 3.
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.
Jul 27, 2020· #3 – This size of the stone ranges from 1/2 to 2 inches long. This material is a great choice for railroad projects and those that require drainage. #5 – Crushed stone #5 is 1 inch or smaller in size. This material is perfect for road and paver base. #8 – These stones are between 3/8 and 1/2 inch long.

Apr 24, 2014· In practice this is done by passing the materials through a set of sieves with openings of different diameter. By separating larger from smaller particles, we can calculate the percentage passing each sieve. Fine aggregates/sand is inert materials in particle form that pass the sieve of 4.75mm and retained on sieve size 75μm/63μm (0.070/0.063mm).
Aug 31, 2020· What is Sieve Analysis of Aggregates? Sieve analysis is the test procedure of dividing a sample of aggregate into fractions, each consisting of particles of the same size.In practice each fraction contains particles between specific limits, these being the openings of standard test sieves.
