The Recycled aggregates properties may be different accordingly types of concrete because the parent concrete was designed for its purposes such as permeable, durable and high strength concrete. Aggregate recycling is a simple process there is no complex method involved. The recycling method includes breaking, removing, and crushing existing concrete into a material with a specified size andGet Price

start with oven-dry aggregate samples of various sizes that had previously been washed to get rid of finer particles. stack the sieves from largest on the top to smallest on the bottom. pour the aggregate over the sieves and position into the mechanical shaker for 10 minutes. obtain the mass of material retained on each sieve; determines the gradation of fine and coarse aggregates, type of
Calculations of Sive Analysis Test for Fine Aggregate: Fineness Modulus: Add values of Cumulative % Retained on each sieve and Divide by 100. Normally the accepted limit of FM is valued between 2.2 to 3.2. A higher value of FM indicates coarser sand, whereas lesser value indicates a finer one.

graded in accordance to Standard Method of Test for Sieve Analysis of Fine and Coarse Aggregates - AASHTO T 27; coarse aggregate fractions of 57.5 % retained on sieve size 9.5 mm (3/8 in.) and fine aggregate fractions of 42.5% retained on sieve size 4.75 mm (No. 4) in accordance to T 380:
B. FINE AGGREGATE Locally available jamuna sand was used in this investigation as fine aggregate. The specific gravity of fine aggregate was 2.30. Cumula e Table 2- RetaResult of Sieve Analysis Test for Fine Aggregate (FA) Fineness Modulus = 275/100 = 2.75. Results of sieve analysis of fine aggregate is given in table 2. S. No. IS Sieve Size
the electronic balance. This process begins with the pan and proceeds through the sieves from fine to coarse, until the last sieve is emptied. After each individual sieve is emptied into the collection pan, a brush, shown in Figure 3, operated through air pressure, cleans the inside of the
Oct 31, 2013 1.1. This test method covers the determination of bulk density (“unit weight”) of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size. Note 1
TEST METHOD FOR THE PARTICLE SIZE ANALYSIS OF SOILS BY HYDROMETER METHOD 1. SCOPE 1.1 This manual describes the procedure used by the Geotechnical Engineering Bureau to determine the distribution of fine-grained particle sizes of soil. The procedure is a modification of AASHTO Test Method T-88-86. Values presented in this manual
Sieve analyses were carried out & about 75% of the plastics were found to be in the range of 1 -1.7mm. 45 nos. of 15cm x15cm x15cm cement concrete Cubes of 1:1:2 (M 25) mix were cast for 0% ,25% , 50% , 75% , 100 % sand being replaced with Pulverized plastic material.
Cumulative percentage of weight retained on all the six sieves = 292 Fineness Modulus of Fine Aggregates = 292/100 =2.92 kg. Now, when it is desired to obtain a combined aggregate of a definite (required) fineness modulus, F, the amount of fine aggregate (x) to be mixed with 1 volume of the coarse aggregate of a given fineness modulus can be easily determined from the relationship:
Jul 23, 2020 Fine aggregates – Size ranging from 4.75 mm to 150 microns. Coarse aggregates – Size ranging from 4.75 mm to 37.5 mm. Boulders – Size greater than 37.5 mm and remember that boulders are used only for special construction. So, largely we have only two categories, fine aggregates, and coarse aggregates.

When fine mesh sieves are involved, hand sieving is not possible. Sieve Analysis as a standard process in the analytical laboratory or in the food and environmental laboratory works perfectly only if the particles are removed from the sieve to the last grain. For efficient and safe cleaning of test sieves, the use of an ultrasonic cleaner is
Sieve analysis The sieve analysis, commonly known as the gradation test, is a basic essential test for determination of the gradation of a polydisperse aggregate. Gradation is the term used for the distribution of aggregate particles, by size, within a given sample. In …

The minimum width of individual chutes shall be approximately 50 percent larger than the largest particles in the sample to be split. For dry fine aggregate where the total sample passes the 9.5 mm (3/8 in.) sieve, the maximum chute width shall be 19 mm (3/4 in.).
