Classification of Aggregates Based on Size. Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates.
Classification of Aggregates According to Nature of Formation Shape wise Classification of Aggregates. 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 ...
Classification of Aggregates. There are so many options for the classification of aggregates, Grain Size; Density; Shape; Geographical Origin; Let’s discuss this in detail! Classification of aggregates based on Grain Size. Based on the grain size, the aggregates are classified into two types. Fine Aggregate; Coarse Aggregate
Aggregate Classification | Types of Aggregates. Aggregates are variously classified on the basis of their grain size, their origin, and their volume-weight as follows: (1.) Aggregate Types on the basis of Grain Size. This is the most common classification, where in two types of aggregates are distinguished: (Fine and Coarse). (i) Fine Aggregates.
According to size, the coarse aggregate is described as graded aggregate of its nominal size .i.e 40mm, 20mm, 16mm and 12.5mm etc. For example a graded aggregate of nominal size 20mm means and aggregate most of which passes 20mm IS sieve.
Classification of aggregates based on: Grain Size. If you separate aggregates by size, there are two overriding categories: Fine; Coarse; The size of fine aggregates is defined as 4.75mm or smaller. That is, aggregates which can be passed through a number 4 sieve, with a mesh size of 4.75mm. Fine aggregates include things such as sand, silt and ...
06-07-2014· According to size the aggregates are classified as: Fine Aggregate Coarse Aggregate All in Aggregate Fine Aggregate It is the aggregate most of which passes 4.75 mm IS sieve and contains only so much coarser as is permitted by specification. According to source fine aggregate may be described as: Natural Sand– it is the aggregate […]
What is an Aggregate? 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. So, we can say that one should know definitely abo...
General Classification of Aggregates. Aggregate size applied in concrete can vary from less than one-tenth of a millimetre to tens of millimeters. In the concrete mix, aggregate particles of different sizes are incorporated. Grading is the term given to the particle size distribution.
According to size, the coarse aggregate is described as graded aggregate of its nominal size .i.e 40mm, 20mm, 16mm and 12.5mm etc. For example a graded aggregate of nominal size 20mm means and aggregate most of which passes 20mm IS sieve.

Size. Size is one of the most important parts of classifying an aggregate. Typically, the size of the aggregate is divided between fine and coarse selections. Fine aggregate like sand is used to fill in the void created when coarse aggregates are combined. Fine aggregate is also used to fill in sand traps on golf courses. Shape
According to size coarse aggregate is determined by ranked mixture of its nominal size i.e. 40 mm, 20 mm, 16mm and 12 mm etc A coarse aggregate which all aggregate passes through a singe IS sieve then it is called coarse aggregate.
Classifying aggregate by its grain size is in most cases the best method from a DIY perspective. As the majority of DIY-based jobs such as mixing cement, mixing mortar, rendering, laying driveways, laying concrete slabs etc involve the use of aggregates defined by their size such as sand, ballast etc, this is a much easier and more accessible method of identifying aggregates.
1.1 This classification defines aggregate size number designations and standard size ranges for mechanical sieve analyses of coarse aggregate and screenings for use in the construction and maintenance of various types of highways and bridges.

Classification of Aggregate According to Nature of Formation Size Wise Classification of Aggregate. The shape of aggregates is an important characteristic since it affects the workability of concrete. So we should take care about the shape of aggregate. Here we discuss the shape wise classifications …
1.1 This classification defines aggregate size number desig-nations and standard size ranges for mechanical sieve analyses of coarse aggregate and screenings for use in the construction and maintenance of various types of highways and bridges. 1.2 Units—The values stated in SI units are to be regarded as standard.
Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks.The term may also be applied to other granular materials.This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain. A single grain can be composed of several crystals.

Aggregate comprising particles falling essentially with narrow limit of size fractions are called single-size-aggregate. For example, a 20mm single-size-aggregate means an aggregate most of which passes through a 20mm IS sieve and major portion of which is retained in 10mm IS sieve.

4.) Flaky Aggregates – The aggregate is said to be flaky when the least dimension of aggregate is less than 3/5th (or 60%) of its mean dimension. Mean dimension is the average size through which the particles pass and the sieve size on which these are retained. For example, mean size of the particles passing through 20 mm sieve and retained on 16 mm sieve is (20+16)/2=18 mm.
26-06-2014· The aggregate is said to be elongated when its length is greater than 180% of its mean dimension. 6. Flaky & Elongated Aggregate. Aggregate is said to be flaky and elongated when it satisfies both the above conditions. Generally elongated or flaky particles in excess of 10 to 15% are not desirable.

11-08-2018· 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.
Aggregate Classification : Size Fine Aggregate Sand and/or crushed stone. < 4.75 mm. F.A. content usually 35% to 45% by mass or volume of total aggregate. Coarse Aggregate Gravel and crushed stone. >4.75 mm. Typically between 9.5 and 37.5 mm.
