Standard Method for Sieve Analysis of Fine and Coarse Aggregates (ASTM C136)

Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates
Today we’re going to demonstrate the dry sieving test method used to determine the particle size distribution of fine and coarse aggregates in accordance with ASTM C136, where a sample of dry aggregate of known mass is separated through a series of sieves with progressively smaller openings to determine the particle size distribution of the test sample.
00:32 The Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates is used primarily to (1) determine the grading of materials proposed for use as aggregates or being used as aggregates, and to (2) determine the compliance of the particle size distribution where applicable specifications are required, and to (3) provide necessary data for quality control of the production of various aggregate products and mixtures containing aggregates.
00:57 Devices required for this test method are: a balance or scale used in testing of fine and coarse aggregate with a readability of 0.1 g for fine aggregate, and 0.5 g for coarse aggregate, or mixtures of fine and coarse aggregate; Test sieves that conform to ASTM E11 specifications; A mechanical sieving device to create motion of the particles to bounce, tumble, or otherwise turn so as to present different orientations to the sieving surface; An oven of appropriate size capable of maintaining a uniform temperature of 110 +/- 5 °C (230 +/- 9 °F); A sieve brush; a sample container or pan; a sieve pan; a sieve stack cover; and a way to record and analysis your test finding.
Sieving Procedure
02:22 The procedure for Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates, we first dry the test sample in an oven at a constant temperature of 110 +/- 5 °C (230 +/- 9 °F). For this demonstration we’re using a Gilson BO-350 Quincy Bench Oven.
Now, measure on a balance or scale the tare weight or unladen weight of your sample container or pan. Now place the test sample into the sample container and measure its gross weight.
Next, select test sieves with suitable openings to furnish enough information required by the specifications covering the material being tested. Nest the sieves in order of decreasing size of opening from top to bottom. Today we’re using Gilson 8in ASTM E11 stainless steel compliance grade test sieves. Place the sieve stack on to a sieve pan.
Now place the test sample into the top sieve and then cap the sieve stack with a sieve cover. Agitate the sieves by means of a mechanical sieving apparatus for a sufficient period of time so that not-more-than 1% by mass of the material retained on any individual sieve will pass that sieve during 1 minute of continuous sieving. For this demonstration we are using the Gilson SS-15 mechanical Sieve Shaker. The SS-15 delivers superior accuracy and repeatability for particle separations for No. 4 to No. 200 size ranges by combining a back and forth lateral motion with an up and down tilting motion which causes test material to travel in an orbit on sieve surfaces.
Once sieving has completed its course, measure and 04:11 record the mass weight of each sample size increment on a scale or balance to the nearest 0.1 gram. Repeat this process for each sieve and the sieve pan. The total mass of the sieved sample should match closely with original mass of test sample before sieving. If the amounts differ by more than 0.3%, based on the original dry sample mass, the results should not be used, and the test should be repeated.
In recording the mass of each sample size and determining the gross test sample mass you should include the total percentage of material passing each sieve, and/or the mass of material retained on each test sieve and pan, and/or the percentage of material retained between consecutive sieves (Report percentages to the nearest whole number, except if the percentage passing the 75-μm (No. 200) sieve is less than 10 %, it shall be reported to the nearest 0.1 %)

Very good work ! Can I use short clips of your video for educational purpose ? Are your video following a specific license ?

[@GilsonCompanyInc]

Yes you can! If you are asking if the video follows a specific sieve standard, yes, ASTMC136. If you are asking for usage license, feel free to use for educational non-profit usage.

[@samuctrebla3221]

@@GilsonCompanyInc Thank you very much, it is much appreciated. The video will indeed be used only for educational non profit, and of course Gilson Company will be cited.

[@GilsonCompanyInc]

If you can. I would like to see your education piece.

what is the duration of dry the sample

[@GilsonCompanyInc]

If you are asking how long should it take to dry the aggregate sample? It depends. Here are some references for you ASTM C 70: Surface Moisture in Fine Aggregate; AASHTO T 85 and ASTM C 127: Specific Gravity and Absorption of Coarse Aggregate; AASHTO T 84 and ASTM C 128: Specific Gravity and Absorption of Fine Aggregate; AASHTO T 255: Total Evaporable Moisture Content of Aggregate by Drying; ASTM C 566: Total Moisture Content of Aggregate by Drying
