1.The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = B/A X 100 where A = weight of oven-dried sample B = weight in 'g' of fraction passing through 2.36 mm IS sieve. 6.Video Aggregate Crushing Value Test

Aggregate crushing value test astm pdf Abrasion Test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is suggested by AASHTO T 96 or ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in Los Angeles Machine. The aggregates are

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 2.1 An ...

The apparatus of the aggregate crushing value test as per IS: 2386 Part IV – 1963 consists of: 1 A 15cm diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in Fig 1. 2 A straight metal tamping rod …

Thus coarse aggregates with a maximum size between 19 mm 3 / 4 in. and 37.5 mm 1 1 / 2 in. may be tested by Test Method C535 or Test Method C131/C131M. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

ABSTRACT. 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 211.1 ACI 211.1, 2009 . In this paper effect of ACV of CA on compressive strength of concrete has been explored.
