Grading of Aggregate - aggregate - Civil …

When as consecutive opening sizes are constantly doubled, the lines at equal intervals represent successive sizes on a logarithmic scale. When The aggregate fraction above 4.75 mm to 80 mm is termed as coarse aggregates and from 4.75 mm be to 150 microns as fine aggregate. All in aggregate comprises both fine and coarse aggregate.

Classification of Aggregates Based on Size

The size of the aggregate bigger than 4.75 mm is considered as the coarse aggregate i.e. basically, all other aggregates which are retained on 4.75mm IS sieve while sieve analysis is performed. According to sources of coarse aggregates, it can be further classified as:

Aggregates - Types of Aggregates | Coarse …

Aggregates are coarse particulate rock-like material consisting of a collection of particles ranging in size from < 0.1 mm to > 50 mm. It includes gravel, crushed rock, sand, recycled concrete, slag, and …

Different Types & Sizes of Aggregate for Concrete ...

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.

Difference Between Fine Aggregate and Coarse …

It is important to mix both fine and coarse aggregate in concrete as coarse aggregate cannot cover the surface area in the manner that fine aggregate does. It is important to remember that the contribution of coarse aggregate in covering the surface area is much lower than fine aggregate. As far as shape is considered, spherical aggregate is considered the best to achieve maximum packing ...

HOW TO CLASSIFY AGGREGATES ACCORDING …

According to size the fine aggregate may be described as coarse sand, medium sand and fine sand. 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 ...

What is the difference between fine aggregate …

Fine aggregate and coarse aggregate differ in various aspect: FA - Fine aggregate. CA - Coarse aggregate. FA comes in size ranging from 4.75 mm to 90 micron, whereas CA ranges from 80 mm to 10 mm. In concrete, FA is responsible for filling up voids and CA is for strength. Source for both are same ,but due to more granulation they differs.

Purpose of Aggregates - …

The finest coarse-aggregate sieve is the same No. 4 used as the coarsest fine-aggregate sieve. With this exception, a coarse-aggregate sieve is designated by the size of one of its openings. The sieves commonly used are 1 1/2 inches, 3/4 inch, 1/2 inch, 3/8 inch, and No. 4. Any material that passes through the No. 200 sieve is too fine to be used in making concrete.

Classification of Aggregates as per Size and …

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. the size range of various coarse aggregates given …

Fine Aggregate: Definition, Size, Density and …

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 ...

METHOD OF TEST FOR THE SOUNDNESS OF AGGREGATES BY USE …

2. Coarse aggregate a. Separate the aggregate on the sieve sizes listed in C-1 and determine the amount of each size fraction. b. Split or quarter a test portion meeting the mass requirements shown below for each size fraction, which makes up 5 % or more of the submitted sample. WEIGHT OF TEST PORTIONS SCHEDULE A. Aggregate Size Passing Sieve Size . Retained Sieve Size Weight * …

Concrete Aggregates - Function, Properties ...

Coarse aggregate is used to describe particles larger than 4.75 mm, and the term fine aggregate is used for particles smaller than 4.75mm. Fine aggregates contain particles in the size range 75 µm to 4.75 mm, and coarse aggregates from 4.75 to about 40 mm, except for mass concrete which may contain particles up to 150 mm.

14. AGGREGATES - cvut.cz
