testing for aggregate use
Aggregate Impact Value Testing Apparatus (AIV) is used to determine the aggregate impact value which provides a rela-tive measure of the resistance of an aggregate to sudden shock or impact. The counter fi tted to the machine automati-cally records the number of blows delivered to the sample. AIV is made from steel protected against corrosion.Aggregate Impact Testing Apparatus product price in India ranges from 250 to 10,00,000 INR and minimum order requirements from 1 to 100. Whether you're looking for Impact Value Testing Machine, Aggregate Impact Value Test Apparatus, Automatic Digital Compression Testing Machine etc, you can explore and find the best products from Tradeindia.
Significance of Aggregate Impact Test. The Aggregate Impact Test, as per IS 2386 (Part IV), measures the resistance of aggregates to sudden impact or shock loading. This test is essential in concrete laboratory testing as it simulates the stresses that aggregates undergo during handling, mixing, and compaction of concrete.
To determine Aggregate Impact Value Using Impact Testing Machine. Apparatus: – Impact Testing Machine: – Weight of hammer is 13.5 to 14.0 kg and Height of Fall is 380±5 mm. Sieves: – required are 12.5, 10.0 and 2.36 mm. Weight Scale: – To measure Weight of the sample. Procedure: – REPARATION OF SAMPLE i) The test sample should .
Different types of aggregate test methods. . The equipment used for the test is the same as the Aggregate Crushing Value (ACV) test (see Table . During the Los Angeles Abrasion Test, grading A was used, which means 9.5/37.5 mm fraction size range, while during the Impact Test the standard, 10/14 mm size was applied. .
The Aggregates Impact Value (AIV) Apparatus is used to determine the aggregate impact value which provides a relative measure of the resistance of an aggregate to sudden shock or impact. Impact Test Fig-3 Impact Test Setup. The aggregate impact test is carried out to evaluate the resistance to impact of aggregates. Aggregates passing 12.5 mm sieve and retained on 10 mm sieve is filled in a cylindrical steel cup of internal dia 10.2 mm and depth 5 cm which is attached to a metal base of impact testing machine.It is for determining the aggregate impact value and has been designed in accordance with IS:2386 (Part 4 ), IS:9377. The sturdy construction consists of a base and support columns to form a rigid frame work around the quick release trigger mechanism to ensure an effective free fall of the hammer during test.
Aggregate Impact Test Procedure as Per IS 2386 Part-4: Equipment For Aggregates Impact Test: Aggregate Impact Testing machine: An Impact testing machine for aggregate comprising the following. The aggregate impact test apparatus should be supported over a level and plane concrete floor or stone block. The Aggregate Impact Value (AIV) test, outlined in IS 2386 Part IV, evaluates the impact resistance of aggregates. This is performed with an impact testing apparatus, using a specific procedure and sample preparation method. Aggregates acceptable for wearing surfaces in concrete should not exceed a 45% impact value and for bituminous concrete, 30%. The .Crushing test and Impact test are very important to estimate strength and toughness characteristics of the road aggregate. Extensive experimental procedures and different sets of equipment are .
