aggregate classifier sieves
A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil 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.

Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS: 2386 (Part I) – 1963. In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over different sieves.
Jul 07, 2014· According to size the aggregates are classified as: Fine Aggregate Coarse Aggregate All in Aggregate Fine Aggregate It is the aggregate most of which passes 4.75 mm IS sieve and contains only so much coarser as is permitted by specification. According to source fine aggregate may be described as: Natural Sand– it is the aggregate […]
The important characteristics of aggregates for concrete are listed in Table 5-2 and most are discussed in the following section: Grading.

Sieve Analysis Test . Testing objectives: The Standard grain size analysis test determines the relative proportions of different grain sizes as they are distributed among certain size ranges.. Need and Scope: The grain size analysis is widely used in classification of soils. The data obtained from grain size distribution curves is used in the design of filters for earth dams and to determine ...

Oct 26, 2012· 4. The sample was placed on the top sieve and the sieves was agitated by mechanical sieve shaker for a sufficient period so that after completion, not more than one percent by weight of the residue on any individual sieve will pass that sieve. 5. The weight of each size increment was determined by weighing the residue contained on each sieve.
aggregates using the pycnometer, moisture by weight loss and absorption value of coarse or fine aggregates. Aggregate Sample Reduction IM 336 Aggregate field sample reduction methods • Mechanical splitters for aggregates in a surface dry condition • Miniature stockpile for damp, fine aggregate …
Nominal maximum aggregate size (NMAS). The largest sieve that retains some of the aggregate particles but generally not more than 10 percent by weight. Superpave mix design defines nominal maximum aggregate size as “one sieve size larger than the first sieve to retain more than 10 percent of the material” (Roberts et al., 1996 ).
May 15, 2002· Sieves and screen are usually used for larger particle sized materials i.e., greater than approximately 50µm (0.050mm). Size Equivalents. Two scales that are used to classify particle sizes are the US Sieve Series and Tyler Equivalent, sometimes called Tyler Mesh Size or Tyler Standard Sieve …

The AASHTO Soil Classification System was developed by the American Association of State Highway and Transportation Officials, and is used as a guide for the classification of soils and soil-aggregate mixtures for highway construction purposes. The classification system was first developed by Hogentogler and Terzaghi in 1929, but has been revised several times since.

• The purpose of sieve analysis is to determine whether or not a particular grading is suitable. The related problem of grading is the combining of fine and coarse aggregates so as to produce desired grading (See Table 4.5, 4.6). The main factors governing the desired aggregate grading are:

as noted on the Classification of Aggregates table. Class AP is the highest class and is assigned to aggregates which meet the requirements for all INDOT uses. Some INDOT contracts specify type AP aggregates for use in on-grade application of portland cement concrete. Parameters concerning type AP aggregate are contained in ITM 210. Aggregates
The size of the aggregate bigger than 4.75 mm is considered as the coarse aggregate i.e. basically, all other aggregates which are retained on 4.75mm IS sieve while sieve analysis is performed. According to sources of coarse aggregates, it can be further classified as: (a) Uncrushed Gravel or Stone: It results from natural disintegration of rock.

This is the most common classification, where in two types of aggregates are distinguished: (Fine and Coarse). (i) Fine Aggregates. In the Fine Aggregates, the grain-size lies between 4.75 mm and 0.15 mm. In other words, these pass-through from sieve with the mesh size of 4.75 mm and are retained on a sieve of 0.15 mesh size.
The grain size characteristics of soils that are predominantly coarse grained are evaluated by a sieve analysis. A nest of sieves is prepared by stacking test sieves one above the other with the largest opening at the top followed by sieves of successively smaller openings and a catch pan at the bottom. Opening mesh sizes of commonly used sieves are shown in table
