”The aggregate crushing value gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load . With aggregate crushing value 30 or higher’ the result may be anomalous and in such cases the ten percent fines value should be determined instead.

AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 12.5mm, 10mm and 2.36mm.

For determination of the aggregate crushing value of coarse aggregate, which passes 12.5 mm. IS sieve and retained on 10 mm. IS sieve. Reference Standard IS: 2386 (Part IV)-1963 Methods of test for aggregate for concrete Part IV Mechanical Properties.

Feb 25, 2012· So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate are mild tough to have the resistance pressure under traffic wheel loads such as car, lorry, motorcycle and etc.

BS 812 part 110 describes a method to determine the aggregate crushing value (ACV) which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.

The aggregate crushing value (ACV) provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available: 150 (standard) and 75 mm dia. The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure.

Procedure to determine Aggregate Crushing Value i) The aggregates passing through 12.5mm and retained on 10mm IS Sieve are oven-dried at a temperature of 100 to 110 o C for 3 to 4hrs. ii) The cylinder of the apparatus is filled in 3 layers, each layer tamped with 25 strokes of a tamping rod.

This paper reports an experimental investigation carried out to establish a mathematical relationship between aggregate crushing value (ACV) and ten percent fines aggregate crushing value (TFV) for some aggregates in Nigeria. Such a mathematical relationship, usually established through regression ...

Nov 03, 2013· Aggregates with lower crushing value indicate a lower crushed fraction under load and would give a longer service life to the load and hence a more economical performance.Weaker aggregates if used would get crushed under traffic loads, would produce smaller pieces not coated with binder and these would be easily loosend out …

Aggregate crushing value of aggregates with cement… BS 812 part 110 describes a method to determine the aggregate crushing value (ACV) which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a …

BS 812 part 110 describes a method to determine the aggregate crushing value (ACV) which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.

Feb 27, 2014 aggregate crushing value test discussion … conclusion for aggregate crushing value test report, … Aggregate Abrasion Value; Sieve Analysis » Learn More. aggregate toughness/ abrasion resistance and durability/soundness. Numerous tests have been developed to empirically characterize aggregate without, necessarily . are …

May 08, 2013· Aggregate crushing Value =(WB/WA) × 100 Record The mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material. to the first decimal place.1 g (W B) Calculation The ratio of the weight of fines formed to the total sample weight in each test is to be expressed as a …

This angular fragmentation during crushing of rock into aggregate for concrete ... be made in order to improve the project, followed by a summary and conclusion. .... Interestingly, the 10%FACT value for wet conditions for quartzite was initially...

Apr 10, 2012· Calculations: Aggregate Crushing Value = (B/A) * 100 % * The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. * Aggregate crushing value < 45% for aggregates used for concrete for non wearing surfaces and <25% for wearing surfaces …
