Aggregate Crushing Value Test Procedure and Limits 2019 Apr 24 2019 Crushing value of aggregate is the resistance strength after applying a fixed load Why is Aggregate Crushing Value
Specified limits of aggregate crushing value 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 pression testing machine is sieves of sizes 125mm 10mm and 2
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 236 mm sieve when a sample of aggregate passing the 132 mm and retained on the 950 mm sieve is subjected to crushing under a gradually applied pressive load of 400 kN 2 APPARATUS 21 An openended steel cylinder of 150 mm nominal
Aggregate Crushing value test procedure of Coarse aggregate is required to find out the relative measure of resistance of an coarse aggregate crushing under gradually applied pressive load We described the procedure of crushing value of aggregate test as per IS Code with Crushing value apparatus and Limits

Aggregate crushing value limit We provide you with all accessories of mining machinery and equipment produced by our pany with plete models reliable performance stability and durability Ensure the first time to meet customer parts replacement
For the Aggregate crushing value test an aggregate sample passing through 125 mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 C to 110 C then cooled to room temperature
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV per is code it should not be more than 25 for wearing surfaces 45 for non wearing surfaces Learn More Impact and Crushing Value
Sep 24 2010Then crushed aggregates are then sieved through 236 mm sieve and weight of passing material is expressed as percentage of the weight of the total sample which is the aggregate crushing value A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates
Oct 09 2018However it can be explain as the aggregate crushing value which is defined as a ratio of the weight of fines passing the specified sieve to the total weight of the sample expressed as a percentage The value is usually recorded up to the first
Aggregate Abrasion Value The apparatus used in this test are Los Angles abrasion testing machine IS Sieve of size 17mm Abrasive charge 12 nos cast iron or steel spheres approximately 48mm dia and each weighing between 390 and 445g ensuring that the total weight of
The aggregate crushing value ACV provides relative measure of the resistance of an aggregate to crushing under a gradually applied pressive load Two versions available 150 standard and 75 mm dia The apparatus prehend cylinder plunger base plate tamping rod and measure

Aggregate crushing value test limitations he aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied pressive load 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
The aggregates should therefore have sufficient toughness to resist their disintegration due to impact This characteristic is measured by impact value test The aggregate impact value is a measure of resistance to sudden impact or shock which may differ from its resistance to gradually applied pressive load
Jul 16 2014Aggregate impact value test also gives an indirect indication of the strength characteristics of aggregate Aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates It has been found that for majority of aggregates the aggregate crushing value and aggregate impact values are numerically similar within close limits
Objective 1 Determine the aggregate crushing value of coarse aggregate 2 Assess suitability of coarse aggregates for use in different types of road Theory The aggregate crushing value give a relative measure of the resistance of
Impact and Crushing Value Aggregate Crushing Value ACV Sets UTA0630 Aggregate Crushing Value ACV Set 150 mm BS UTA0640 Aggregate Crushing Value ACV Set 75 mm BS The Aggregate Crushing Value ACV Test Set measures how resistant an aggregate is when being crushed under a gradually applied pressive load
