Apr 13 2017nbsp018332Fine aggregate is a building material which is opposite to the coarse aggregate. It is a loose material with skeleton or filling effect in concrete. The average particle size is below 4.75mm. Fine aggregate also known as mechnism sand.It can be produced by impact crusher or sand making machine to replace natural sand.
Before pursuing a PhD degree he was involved in both readymix concrete and aggregate production for more than five years. the aforementioned surplus fines from crushing operations are expected to be the next best alternative due to both great availability and suitable physical properties.

10% fines aggregate crushing value (10% FACT) determined in accordance with TMH1 method B2 shall be not less than the appropriate value in table 3602/2 column 3. The Aggregate Crushed Value (ACV) determined in accordance with TMH1 method B1 shall not exceed the appropriate value
Aggregate crushing value (ACV) and 10% fines Aggregate response to gradually applied compressive load can differ from sudden load impact in concrete. Therefore ACV which is a relative measure of the aggregate resistance to crushing under a gradually applied load is conducted on both aggregates to check their individual resistance.
Sep 12 2015nbsp018332Then crushed aggregates are then sieved through 2.36 mm sieve and weight of passing material (W2) is expressed as percentage of the weight of the total sample (W1) which is the aggregate crushing value. Aggregate crushing value = (W1/W2)100. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be

The drum is rotated for a specified number of revolutions. Afterward the aggregate is removed from the drum and sieved on a No. 12 (1.70 mm) sieve. The aggregate retained on the sieve is weighed and the difference between this weight and the original weight is expressed as a percentage and reported as the L.A. abrasion loss value.
$\begingroup$ You seem to be considering quotcrushed gravelquot as a blend of coarse and fine aggregate. I don't believe that is correct in general but in the particular text referenced by @hazzey it states that quotthe fine aggregate shall be produced by crushing stone gravel or slag that meet the requirements for wear and soundness specified for

In road construction the quality of aggregates is assessed by the crushing strength of aggregates.For higher quality of roads the aggregate should possess low aggregate crushing value. Here I am going to teach you how to determine the crushing strength of aggregates.First let us check what are the various apparatus needed for this experiment.
Mineral aggregates are used in all fields of the construction industry to produce bituminous misture concrete mortars to be used in structures fill materials railway ballast etc. For this reason we have given particular attention to all testing methods.
Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits called pitrun gravel consist of gravel and sand that can be readily used in concrete after minimal processing. Natural
