There is an arbitrary line drawn between coarse aggregate and fine aggregate at the No 4 sieve, or approximately A -inch square opening Coarse aggregate has most of the product rationed on a No 4 sieve and fine aggreate, like sand, passes a No 4 sieve This arbitrary line explains our having coarse-aggregate and fine-aggreate tables for.

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.

Jan 15, 2016· Aggregate serves as a reinforcement to add strength to composite materials such as concrete Aggregates can be categorized into three groups: fine aggregate, coarse aggregate, or all-in aggregate Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 475 mm IS sieve.

• Aggregates are divided into either ‘coarse’ or ‘fine’ categori - Coarse aggregates are particulates that are greater than 475mm The usual range employed is between 95mm and 375mm in diameter - Fine aggregates are usually sand or crushed stone that are less than 955mm in diameter.

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.

Gap-graded aggregate consists of coarse aggregate particles that are similar in size but significantly different in size from the fine aggregate A core slice of gap-graded concrete shows a field of fine aggregate interspersed with slightly isolated, large aggregate pieces embedded in the fine aggregate.

aggregate size numbers Fine aggregate or sand has only one range of particle sizes for general construction and highway work The grading and grading limits are usually expressed as the percentage of material passing each sieve Fig 5-6 shows these limits for fine aggregate and for one size of coarse aggregate.

Apr 14, 2017· A coarse aggregate that has sizes of particulars mainly belonging to a single sieve size is known as single size aggregate For example 20mm single size aggregate mean an aggregate most of which passes through 20mm IS sieve and its major portion of which is retained in 10mm IS sieve.

Thus a richer mix requires a lower content of fine aggregate than a lean mix If the grading of fine aggregate (sand) is such that it is deficient in finer particles, in that case increase in fine/coarse aggregate ratio will not prove useful as it may lead to an excess of middle sizes resulting in.

Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index number It is calculated by performing sieve analysis with standard siev The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fine aggregate.
Live ChatNov 21, 2016· • Coarse aggregate is used to describe particles larger than 475 mm, and the term fine aggregate is used for particles smaller than 475mm; typically, fine aggregates contain particles in the size range 75 µm to 475 mm, and coarse aggregates from 475 to about 50 mm, except for mass concrete which may contain particles up to 150 mm.
