gradation of aggregates is determined from sieve analysis, in which a representative sample of aggregate is passed through a series of sieves in top to bottom and the weight retained in each sieve – expressed as a percentage of the sample weight – is compared with the grading limits specified.by this test we calculate finesse modulus of our aggregate that define as summing the cumulative

here is the full procedure on “how to do the sieve analysis of aggregate.” 1. taking the representative sample. take the samples with a minimum of 25kg. in the aggregates stockyard or storage bin by scattered basis, take from bottom, middle and top of the dumped aggregate, do not take from just one area. place the sample in clean container.
1) sieves - for coarse aggregates 15 in. x 23 in. or 14 in. x 14 in. screens are recommended with sieve designations 2 in., 1 1/2 in., 1 in., 3/4 in., 1/2 in., 3/8 in., no. 4, no.8 and pan. for fine aggregates 8 in. round sieves are standard with sieve designations 3/8 in., no. 4,
sieve analysis sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.this is done by sieving the aggregates as per is: 2386 (part i) – 1963. in this we use different sieves as standardized by the is code and then pass aggregates through them and thus collect different sized particles left over different sieves.
for a good fine aggregate, the fm should be between 2.3and 3.1 (astm range for fine aggregates). 5 a fm of 4 can be interpreted to means that the fourth sieve from bottom i.e. sieve no. 16 is the average size of the aggregate particles in the given sample.

aggregate is the granular material used to produce concrete or mortar and when the particles of the granular material are so fine that they pass through a 4.75mm sieve, it is called fine aggregate. it is widely used in the construction industry to increase the volume of concrete, thus it is a cost saving material and you should know everything

fine aggregate. the fine aggregate shall consist of natural sand, manufactured sand, or a combination thereof. 1. grading. the fine aggregate shall not pass 45% from a single sieve and retained on the next consecutive sieve as shown in table-1. the fineness modulus of the fine aggregate shall be not less than 2.3 and more than 3.1.
sieve analysis of fine aggregates astm c136 scope this test method covers the determination of the particle size distribution of fine and coarse aggregates by sieving. a weighed sample of dry aggregate is separated through a series of sieves of progressively smaller openings for determination of
fine aggregate is well graded and has a gradation of particle size that spans evenly the size from coarsest to finest. this conclusion is supported by computed coefficients of uniformity and gradation which is 6. 79 and 1. 03 for (well graded) fine aggregates,
the fineness modulus is used in us practice and is a measure of the grading of fine aggregates. it can be calculated from a sieve analysis by adding the cumulative percentages of fine aggregates retained on the following sieve sizes; 0.15mm, 0.30mm, 0.60mm, 1.18mm, 2.36mm and 4.75m. this value is then divided by 100 to give the fineness modulus.
grading of aggregate is the particle size distribution, which is determined by sieve analysis. the particle size distribution of a mass should be such that, voids between the coarse aggregate should be filled by fine aggregates. the grading of the aggregate affects the workability of concrete. when grading of aggregate is done by sieve analysis.
sieve analysis of fine and coarse aggregate introduction aggregates perform different purposes in civil engineering, including functioning as component materials for portland cement concrete, hot mix asphalt, and bounding foundation layers beneath buildings and pavements.
the grading also known as sieve analysis is simply an exploration of particle size distribution and represented as % passing from each sieve. therefore, to examine the grading of fine aggregates, the common procedure of sieve analysis shall be adopted by using the set of sieves as mentioned in the section of grading requirements table.
aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. those particles that are predominantly retained on the 4.75 mm (no. 4) sieve, are called coarse aggregates. those particles passing the 9.5 mm (3/8 inch)
procedure. the sample is dried to constant mass in the oven at a temperature of 1100±50c and all the sieves which are to be used in the analysis are cleaned. the oven dry sample is weighed and sieved successively on the appropriate sieves starting with largest. each sieve is shaken for a period of not less than 2minutes.
with more than 60% of aggregate passing through the 9.5mm sieve, the majority of coarse aggregate are shown to be in the range of 4.75mm and 9.5mms. when both aggregate mixtures, fine and coarse are combined, it can be seen through the combined aggregate
aim. to determine the particle size distribution of fine and coarse aggregates by sieving as per is: 2386 (part i) – 1963. principle. by passing the sample downward through a series of standard sieves, each of decreasing size openings, the aggregates are separated into several groups, each of which contains aggregates in a particular size range.
