A Detailed Guide on Grading of Aggregates.
F = Fineness modulus of desired mixed aggregate. F f = Fineness modulus of fine aggregate. The above relationship is illustrated in the following example. F = 5.5. F c = 6.75. F f = 2.92. To Determine: Volume of fine aggregate (x) in percentage terms of volume of coarse aggregate. x=F c – F / F – F f => 6.75 – 5.3 / 5.5-2.92 x 100 => 48.5 % approximately.
Study on Tests Fine and Coarse Aggregate …
18.12.2013 · The analysis is conducted to determine the grading of materials proposed for use as aggregates or being used as aggregates. The term fineness modulus (F.M) is a ready index of coarseness or fineness of the agrial. It is an empirical factor obtained by adding the cumulative percentages of aggregates retained on each of the standard sieves and dividing this sum arbitrarily by 100.
HOW TO CLASSIFY AGGREGATES ACCORDING …
07.07.2014 · IS specifications classify the fine aggregate into four types according to its grading as fine aggregate of grading Zone-1 to grading Zone-4. The four grading zones become progressively finer from grading Zone-1 to grading Zone-4. 90% to 100% of the fine aggregate passes 4.75 mm IS sieve and 0 to 15% passes 150 micron IS sieve depending upon its grading zone. Coarse Aggregate. It is …
IS 383 (1970): Specification for Coarse and Fine ...
25.09.1970 · according to the grading characteristics of the fine aggregates used; the ratio of fine to coarse aggregate being reduced as the fine aggregate becomes finer from Grading Zones I to IV. In particular, the correct design of the mix becomes increasingly important as the grading of the fine aggregate approaches the coarse outer limit.of Grading Zone I or the
WHAT IS THE GRADING LIMITS FOR FINE …
03.07.2014 · To describe an aggregate by its maximum and minimum size is not sufficient. It has to be graded from its minimum to maximum size. IS-383 recommends the following grading limit for fine aggregates. Grading Limits For Fine Aggregates Sieve Size Percentage of Passing For Grading Zone-I Grading Zone-II Grading Zone-III Grading Zone-IV 10 mm 100 […]
HOW FINE AGGREGATES AFEECTS CONCRETE …
21.08.2019 · Fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially. Various factors such as fine aggregate fineness modulus, moisture content, specific gravity, and silt content affect the mix proportions of concrete. Fineness modulus specifies how much fine aggregate is required in a given mix design.

Determination of Moisture Content of …
A quick and reasonably accurate method of determining the moisture content of fine aggregate is to mix it with an excess of calcium carbide in a strong air-tight vessel fitted with pressure gauge. Calcium carbide reacts with surface moisture in the aggregate to produce acetylene gas. The pressure of acetylene gas generated depends upon the moisture content of the aggregates. The pressure gauge ...
