4.4 Sieve agitators such as plastic or leather rings, or small rubber balls may be required to break up agglomerates on finer sieves, usually those smaller than 300 mm in opening (ISO 3310-1) or US sieve No. 50. 4.5 A dispersion agent 2) should be used to facilitate sieving of high-fat or similar materials. 4.6 Sieve openings must be kept free ...
each sieve in the stack. Column (D) is calculated from the values in column (C) by dividing each individual weight by the total weight and multiplying by 100. The Cumulative % Passing, column (E), is the fraction of the total weight that passes through each individual screen. It is calculated for a given size by subtracting the material
Basically, sieve equipments consist of a set of sieves preferably with the quality of shocker in accordance with its speed range. The speed of the sieve shoker motor ranges from 0.1000 2.pm (revolution per minute), 0-1200 r.p.m, 0-1500 r.p.m upwards to 2600 r.p.m and …

NOTE 3—Where sieve analysis, including determination of material finer than the 75-µm sieve, is the only testing proposed, the size of the sample may be reduced in the field to avoid shipping excessive quantities of extra material to the laboratory. 7.3 Fine Aggregate—The size of the test sample, after drying, shall be 300 g minimum.

In determining sieving time for sieve sizes larger than 4.75 mm (No. 4), limit the material on the sieve to a single layer of particles. Overload Determination For sieves with openings smaller than 4.75 mm (No. 4), the mass retained on any sieve shall not exceed 7 kg/m2 (4 g/in2) of sieving surface.
Weigh the material retained on each sieve size to the nearest 0.1 g. Ensure that all material entrapped within the openings of the sieve are cleaned out and included in the weight retained. This may be done using brushes to gently dislodge entrapped materials. The 8 …
The table is for sieve openings in mm (millimeters). On the identification plate of some sieves the sieve opening will be in microns. To convert microns to mm (millimeters): multiply the number of microns by 0.001. Example: On the identification plate of a #16 sieve - the openings indicated are 1190 microns. (1190 x 0.001) = 1.19 mm
material passing the No. 4 sieve. a. If there is insufficient material passing the No. 4 sieve to obtain the required 500 g ± 25 g, use all of the material passing the No. 4 sieve for the fine- aggregate test sample. b. If less than 10 % of the submitted sample is retained on the No. 30 sieve, it
G. Determine the mass of the material retained on each sieve and the catch pan and record on the worksheet in the designated locations as "Mass Retained." H. Check the mass retained for each sieve and refer to the table in the Introduction to determine if any sieve has been overloaded. 1. If no sieve has been overloaded, proceed to Step I. 2.

A sieve is considered overloaded when the mass of the material retained on a sieve exceeds the maximum allowed as follows: 1. For sieves with openings 4.75 μm (No. 4) and larger, the mass in kilograms shall not exceed the product of 2.5 x sieve opening in millimeters x effective area of sieving surface in square meters (the mass in

sieve. (f) Screen the material that passes the 3/4" sieve over the No. 4 sieve. Weigh the material that is retained on the No. 4 sieve and add this weight to the weight of the material retained on the 3/4" sieve. (g) Immediately weigh a moisture sample from the passing No. 4 material to be run either by 'Speedy' or Hot Plate Method.
In determining sieving time for sieve sizes larger than 4.75 mm (No. 4), limit the material on the sieve to a single layer of particles. Overload Determination • For sieves with openings smaller than 4.75 mm (No. 4), the mass retained on any sieve shall not exceed 7 kg/m2 (4 g/in2) of sieving surface.
material being inspected. As a rule, a larger top size material the larger the sample. A 25 lb sample of No. 2 coarse aggregate would not be as representative of the material as a 25 lb sample of natural sand. TWO IMPORTANT DEFINITIONS TO REMEMBER Top Size or Maximum Particle Size--The sieve on which 100 percent of the material will pass.
7. Remove the upper sieve and return material retained to the washed sample. 8. Rinse the material retained on the 75 µm (No. 200) sieve until water passing through the sieve is reasonably clear and detergent or dispersing agent is removed, if used. 9. Return all material retained on the 75 µm (No. 200) sieve to the container by rinsing into

sieve shall be the ¼ in. (6.3 mm) followed by a "pan". During the sieving process, some additional material will pass through the ¼ in. (6.3 mm) sieve into the "pan". Weigh this "pan" material to the nearest 0.01 lb. and record on Line B of the data sheet. Add this material to the minus ¼ in. (6.3 mm) material obtained in Section 5.1.
Materials Finer than 75-μm (No. 200) Sieve in Mineral Aggregates by Washing ASTM C117 - 17 Page 1 of 3 4. Significance and Use 4.1 Material finer than the 75-μm (No. 200) sieve can be separated from larger particles much more efficiently and completely by wet sieving than through the use of dry sieving. Therefore, when accurate
