Aggregates can be classified in many ways. Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here, Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 70 to 80 of total volume of concrete.
Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydrauliccement concrete, or iron blastfurnace 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 38 inch
Fine Aggregate If the aggregate size is less than 4.75mm, then it is called as Fine aggregate. The minimum size of fine aggregate is 0.075mm is preferred for concreting works Coarse Aggregate If the aggregate size is more than 4.75mm, then it
When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete.
It is the aggregate composed of both fine aggregate and coarse aggregate. According to size Allinaggregate is described as allinaggregates of its nominal size, i.e. 40mm, 20mm etc. For example, all in aggregate of nominal size of 20mm means an aggregate most of which passes through 20 mm IS sieve and contains fine aggregates also.
There are seven standard sieves for fine aggregates ranging from No. 100 to 38 and 13 standard sieves for coarse aggregate ranging from No. 16 to 4. For example coarse aggregate has a standard grading requirement for each different size from 1 to 8. A 1 aggregate is a nominal size of 3 to 1 inches and a 8 aggregate is a nominal
Coarse aggregates are larger size filler materials in construction. Size of Particles. Fine aggregates are the particles that pass through 4.75 mm sieve and retain on 0.075 mm sieve. Coarse aggregates are the particles that retain on 4.75 mm sieve. Sand, surki, stone screenings, burnt clays, cinders, fly ash, etc are used as fine aggregate in
In nature, aggregates are available in different sizes. The size of aggregate used may be related to the concrete mix proportions, type of the work etc. The size of aggregate is mainly divided into two categories 01. Fine Aggregate. 02. Coarse Aggregate
Aggregate materials are generally broken up into two classifications of size fine and coarse aggregate. Coarse aggregates are typically sizes larger than the 4 sieve. Fine aggregates are typically sizes smaller than the 4 sieve. What people refer to as 34dust34 is typically aggregate smaller than the 200 sieve. Simple enough right Any questions
Air cooled blast furnace slag fine aggregate 2.6 Granulated blast furnace slag fine aggregate 2.1 Steel furnace slag, both fine and coarse 3.2 Gravel Coarse Aggregates There is a specific requirement for gravel coarse aggregates regarding crushed particles.
Fine aggregate is the essential ingredient in concrete that consists of natural sand or crushed stone. The quality and fine aggregate density strongly influence the hardened properties of the concrete.. The concrete or mortar mixture can be made more durable, stronger and cheaper if you made the selection of fine aggregate on basis of grading zone, particle shape and surface texture, abrasion
shows these limits for fine aggregate and for one size of coarse aggregate. There are several reasons for specifying grading limits and nominal maximum aggregate size they affect relative. 82.

Coarse aggregates are classified into two main groups i singlesize aggregate and ii graded aggregate. Singlesize aggregate is based on a nominal size specification. It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25 of which is retained in the next lower sieve.
The minimal size of coarse aggregate is 40 mm, 20 mm, 16 mm and 12.5 mm. Variation among Fine and Coarse Aggregate based on source According to the source, the coarse aggregate is classified into the following three categories a. Uncrushed Gravel or Stone that is developed by decomposing the rocks in normal way. b.
Aggregate size description of aggregate in terms of lower d and upper D sieve sizes see later text. Coarse aggregate designation given to the larger aggregate sizes with D greater or equal to 4 mm and d greater than or equal to 2 mm. Fine Aggregate designation given to the smaller aggregate sizes with D less than or equal to 4 mm.
To describe an aggregate by its maximum and minimum size is not sufficient. It has to be graded from its minimum to maximum size. IS383 recommends the following grading limit for fine aggregates. Grading Limits For Fine Aggregates Sieve Size Percentage of Passing For Grading ZoneI Grading ZoneII Grading ZoneIII Grading ZoneIV 10 mm 100
The nominal size of coarse aggregate is 40 mm, 20 mm, 16 mm and 12.5 mm. Difference between Fine and Coarse Aggregate According to source The basic difference between fine and coarse aggregates not only includes the size specifications, but you can classify these two based on their sources.
