Fine aggregates are less than mm in size and content usually 35% to 45% by mass or volume of total aggregate. Classification of fine Aggregates as per IS: Terminology For the purpose of this standard, the definitions given in IS 6461 (Part 1) and the following shall apply.
Aggregate Crushing Value (ACV) is an index of loss of coarse aggregate (CA) under sustained loading. However, ACV is not considered in concrete mix design according to ACI (ACI, 2009). In this paper effect of ACV of CA on compressive strength of concrete has been explored. Coarse
Sep 12, 2015· Then crushed aggregates are then sieved through 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 regarded as weak aggregates. Also Read: .
Mechanical Properties Aggregate Crushing Value/Ten Percent Fines Value The aggregate crushing value/ten percent fines value, when determined in accordance with IS 2386 (Part 4) shall be as follows: a) For aggregates to be : 30 percent, Max used in concrete for wearing surfaces, (such as runways, roads, pavements, tunnel lining carrying water, spillways and stilling basins) 3 IS 383 :2016 b) .
The ratio of fine aggregate and coarse aggregate is which is again a bit on the higher side, but not out of proportion with similar values used by other researchers.

The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS An openended steel cylinder of 150 mm nominal .
Aggregate Crushing Value and 10% Fines Value Aggregate Crushing Value (ACV) Introduction. One of the requirements, for the suitability of aggregates for construction, is the ability of the aggregate to resist crushing. The Aggregate Crushing Value gives a relative measure of the resistance of the aggregate to crushing under a
· Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index .
Coarse aggregate occupies 70% to 80% of the volume of concrete. Aggregates are the material that the cement paste coats and binds together. The quality of aggregates imposes a significant impact on the properties of concrete like workability, strength, weight, durability etc. ...

Crushed aggregate have irregular, angular particles that tend to interlock when compacted or consolidated. The crushed stone or crushed gravel aggregate make the asphalt or concrete mix somewhat difficult to place. To improve the workability, many mixes contain both angular and round particles. The coarse aggregate particles are
