This percentage is known as a crushing value of aggregate. This percentage should not exceed 30% of the total weight of aggregate taken for the test. The aggregate crushing value test result should not be more than 30 % for the concrete used for roads and pavements and, in case of other structures; it may be permitted up to 45%
DetailsAGGREGATE ABRASION VALUE This test helps to determine the abrasion value of coarse aggregates as per IS: 2386 (Part IV) – 1963. The apparatus used in this test are Los Angles abrasion testing machine, IS Sieve of size – 1.7mm, 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 charge is
DetailsThis is known as aggregate impact value test IS 283-1970 Result: Aggregate impact value shall not exceed 45 % by weight for aggregate used for concrete other than wearing surface and 30 % by weight for concrete for wearing surfaces such as runway, roads, and pavements
DetailsAggregate Impact Value This test is done to determine the aggregate impact value of coarse aggregates as per IS: 2386 (Part IV) – 1963..... for non wearing surface its max. limit is 45%
DetailsAfter completion of circulation, collect the aggregate sample and place it on a tray. Then the collected aggregate sample should be sieved through 1.70mm IS sieve. Now weigh the aggregate which retained through the IS 1.70mm as W2. Abrasion Value Calculation. Abrasion Value = (W1-W2/W1) x 100. W1 – Weight of Dried Aggregate Sample
DetailsDetermination of aggregate crushing value 1.Aim 1) to determine the aggregate crushing value of coarse aggregates .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
DetailsAIM: Determination of Aggregate Crushing Value Crushing Strength of Coarse Aggregate. Aggregate Crushing value test IS Code is 2386-4 (1963): Methods of Test for Aggregates for Concrete
DetailsThe crushing strength or aggregate crushing value of a given road aggregate (stone) is obtained as per IS-2386 Part- 4. AGGREGATE CRUSHING VALUE TEST, CRUSHING VALUE TEST OF AGGREGATE, IS 2386 (PART-4)-1963 Hi friends, you are welcomed in the world of Civil Allied Gyan. Here I have explained about crushing value test of road aggregate
DetailsAggregate Crushing Value AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – 1963.as per is code it should not be more than 25% for wearing surfaces & 45% for non wearing surfaces
DetailsIt is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for cement concrete road. The aggregate whose crushing value is …

DetailsMar 29, 2021 · If the aggregate crushing value is less than 10, means an exceptionally strong aggregate, Whereas crushing value of 35 and above means a weak aggregate. Relevant codes for aggregate crushing test IS 2386(Part 4):1963
DetailsAGGREGATE 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. Procedure to determine Aggregate Crushing Value
DetailsThis percentage is known as a crushing value of aggregate. This percentage should not exceed 30% of the total weight of aggregate taken for the test. The aggregate crushing value test result should not be more than 30 % for the concrete used for roads and pavements and, in case of other structures; it may be permitted up to 45%
DetailsThe aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve. Aggregate crushing value= (W2 / W1) × 100
