Energy-based indicators of soil structure by automatic dry sieving
The results of dry sieving methods are called "dry aggregates". Wet sieving is carried out in two ways: without ( le Bissonnais, 1996l ; Marquez et al., 2004 ) or after the pre-capillary water saturation ( Kemper and Chepil, 1965 ; Nimmo and Perkins, 2002 ) of an air-dried sample, resulting in " water-stable aggregates ".

Gradation and Size – Pavement Interactive
The smallest sieve through which 100 percent of the aggregate sample particles pass. Superpave defines the maximum aggregate size as "one sieve larger than the nominal maximum size" (Roberts et al., 1996 [1]). Nominal maximum size. The largest sieve that retains some of the aggregate particles but generally not more than 10 percent by weight.

Atterberg Limits Test, What is the Purpose?
For all the Atterberg limits tests, soil samples consist of material passing a No. 40 (425µm) test sieve and are prepared for each test using wet or dry methods described in the standards. Moisture in Test specimens is adjusted by adding water, mixing with a spatula, and allowing to condition for at least 16 hours.

After that take weight the retained residual cement which left on the 90 µm sieve as W2. Fineness test for cement formula is (W2/W1)×100. Fineness test for cement formula = (W2/W1)×100, where, W2 = Cement residue on sieve, W1 = Weight of given sample of cement. Then after, calculate the percentage of Weight of cement-retained on Sieve.

agglomerates. Wait 2 min. Stir the resulting powder gently using a clean dry rod in order to distribute the fines throughout the cement. 2. Fit the tray under the sieve, weigh approximately 10 g of cement to the nearest 0.01 g and place it on the sieve, being careful to avoid loss. Disperse any agglomerates. Fit the lid over the sieve.
CIVL 1101
Therefore, by minimizing the amount of cement, the cost of concrete can be reduced. Sieve Analysis-- determines the grading of an aggregate. Coarse aggregate is that retained on the #4 sieve and fine aggregate is that passing a #4 sieve. In a sieve analysis a series of sieve are used with smaller and smaller openings.

Sieve Analysis
The air jet sieve is a sieving machine for single sieving, i.e. for each sieving process only one sieve is used. The sieve itself is not moved during the process. The material on the sieve is moved by a rotating jet of air: A vacuum cleaner which is connected to the sieving machine generates a vacuum inside the sieving chamber

Aggregates for Concrete
CHAPTER 1—INTRODUCTION. Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete.
