Sieve Analysis of Aggregates

Ref : IS 2386 (Part I)

Purpose : To determine the gradation of aggregates / fineness modulus of aggregates.

Procedure :

Prepare the sample for testing from a larger sample by quartering or by means of the sample driver.

Weigh the air dried sample and successively sieve on the appropriate size starting with the largest.

Shake each sieve separately over a clean tray until not more than a trace passes

Brush lightly with a fine camel hair brush on the 150μ (micron) and 75μ sieves to prevent blocking of the apertures.

A typical format for tabulating the results is given below:
