SIEVE ANALYSIS

A gradation test, or sieve analysis test, is a basic, but essential test, for aggregates, and determines the distribution of aggregate particles, by size, within a given sample, in order to determine compliance with design, production control requirements, and verification specifications. 

The data can be used to calculate relationships between various aggregate, or aggregate blends, to check compliance, and to predict trends during production by plotting gradation curves graphically.

Used in conjunction with other tests, the sieve analysis is a powerful quality control tool.

For sifting purposes, particles larger than three inches are hand sieved. Between 3 inch and 3/4 inch particles, are sifted using a large screen shaker like the Gilson TS 1, or more recently, a heavy duty vibratory sieve shaker, like the Endecotts D 450. The advantage of the latter, is that it may be used for aggregate fines analysis as well.  

Mechanical sieve shakers, if used, must provide a vertical or lateral and vertical motion to the sieve, causing the particles thereon to bounce and turn so as to present different orientations to the sieving surface. Sieve shakers must provide sieving thoroughness within a reasonable time. A series of twelve inch sieves are generally used to separate materials between 1" and the amount retained on a #10 (2.0 mm) sieve. *AASHTO M92. Aggregate fines, defined as those that pass through the #10 sieve, are generally run on 8" or 12" Sieves.Tray shakers are not recommended for use with aggregate fines, so a separate sieve shaker is required.

THE NEW  D450 18 INCH SIEVE SHAKER CAN BE USED FOR BOTH COARSE AND FINE AGGREGATE ANALYSIS, ELIMINATING THE NEED FOR TWO SEPARATE SHAKERS.

BECAUSE OF THE LARGE SURFACE AREA,  RESULTS ARE COMPARABLE TO THOSE ACHIEVED WITH  ELECTRO-FORMED SIEVES

THE  ENDECOTTS EFL 2000 IS USED BY DOTS WORLDWIDE, AND IN THE US, BECAUSE IT PERFORMS WITH BOTH 8 INCH and 12 INCH SIEVES.THIS HEAVY DUTY SIEVE SHAKER HANDLES LARGE VOLUMES OF AGGREGATES, AT REDUCED NOISE LEVELS.
