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.
The apparatus used are –
i) A set of IS Sieves of sizes – 80mm, 63mm, 50mm, 40mm,31.5mm, 25mm, 20mm, 16mm, 12.5mm, 10mm, 6.3mm,4.75mm, 3.35mm, 2.36mm, 1.18mm, 600µm, 300µm, 150µm and 75µm.
ii) Balance or scale with an accuracy to measure 0.1 percent of the weight of the test sample.
The weight of sample available should not be less than the weight given below:-
The sample for sieving should be prepared from the larger sample either by quartering or by means of a sample divider.
Procedure to determine particle size distribution of Aggregates.
i) The test sample is dried to a constant weight at a temperature of 110 + 5oC and weighed.
ii) The sample is sieved by using a set of IS Sieves.
iii) On completion of sieving, the material on each sieve is weighed.
iv) Cumulative weight passing through each sieve is calculated as a percentage of the total sample weight.
v) Fineness modulus is obtained by adding cumulative percentage of aggregates retained on each sieve and dividing the sum by 100.
Reporting of Results
The results should be calculated and reported as:
i) the cumulative percentage by weight of the total sample
ii) the percentage by weight of the total sample passing through one sieve and retained on the next smaller sieve, to the nearest 0.1 percent. The results of the sieve analysis may be recorded graphically on a semi-log graph with particle size as abscissa (log scale) and the percentage smaller than the specified diameter as ordinate.

i need an example for sieve analysis,pleas
i need seive analysis method,limitation&report of 10mm,20mm&course sand in detail also permissible limit
its wonderful write up pls keep it up
sir plz give me all importants of aggregrate
good evening. pls i woud like to know if i could get a seive analysis report on fine sand according to standard from 20 mm seive diameter and below and if i could also have a copy of a semi- log graph for fine and coarse aggregates. thank you
comulative curve & fineness modulus ?
Please give me the seive analisys limits,crushing value of aggregates,impact value of aggregates for results passed or failed
please give me survey practical site
I thought that the aim of sieve analysis experiment is to determine particle sizes of a given soil.The two important parameter in particle size distribution is coefficient of uniformity and curvature, but in a situation were this two parameters can not be obtain from the graph then what will be the end result/conclusion of such experiment?
Kindly send me what should be approx sieve analysis for 20mm aggregate for perfect concrete of M-30 or any other grade of concrete.
URGENT AND IMPORTANT
Finess Modulus of soil is the sum of cumulative percent retain on some specified seive like 2mm,.425mm and .075mm and dividing the sum by 100 not each seive sumof cumulative,
Is it an aggregate gradation?
how to find its fineness modulus?
Please could i have a copy of the semi-log graph sheet used for sieve analysis.
I need sieve analysis method,limitation&repots of 20mm,10mm and fine aggregate FOR M-25. pls kindly send me.
Explaine the theory of sieve analysis
How to get I S sieve size equivalent to B S standard? We are executing a project and sieve size given is in B S Standard. As only IS sieves are available in market, please provide me details.
good afternoon sir i need sieve sizes for the sieve analysis of 20 mm aggregate for perfect mix of M-20
obejective of sieve analysis an procedure of sieve analysis with examples
Sir, i want to know the method of sieve anallysis for stone ballast size 22.4-50 mm,45-63 mm and 45-90 mm
Pls, I need discussion on the use of for grading test and lab report on sieve analysis of crushed aggregate
