Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Mar 21, 2018 March 21, 2018. Cornelius. Cornelius. The aim of aggregate impact test is to determine the relative measure of the resistance of aggregate to sudden shock or impact in which in some aggregate differs from its resistance to a slowly applies compressive load. The property of a material to resist impact is known as toughness.

Testing aggregates - Part 111: Methods for determination of ten per cent fines value (TFV. Download. Related Papers. The Government of the Hong Kong Special Administrative Region Aggregates for Concrete CS3:2013 Construction Standard. By TA THU GIANG (CONSTRUCTION/JVTT) Dec 19, 2019 In order to evaluate the resistance to impact of aggregate, the aggregate impact test is conducted. Aggregate impact value gives the idea about how much impact load can be resisted by aggregate. Actually, aggregate should be sufficiently tough to resist their disintegration due to impact. This distinctive property is measured by impact value test.

With aggregate of aggregate impact value (AIV) higher than 30 the result may be anomalous. Also aggregate sizes larger than 14 mm are not appropriate to the aggregate impact test. The standard aggregate impact test shall be made on aggregate passing a 14. mm BS test sieve and retained on a 10.0 mm BS test sieve. Jul 01, 2019 Procedure of Aggregate Impact value test The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled. Sieve the material through 12.5mm and 10.0 mm IS sieves.

Importance of Impact Test on Aggregates. The impact test on aggregate is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.. The need for impact value test is used to measure the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or … Dec 15, 2017 11. 11 CONCLUSION From the experiment, we get the value is 17% and 15%less than the requirement of JKR’s; 20%.Aggregate physical property must lower Aggregate Impact Value, AIV because is tougher and resistance to crushed. We can conclude that the aggregate been used are medium toughand resistant to be crash.

Feb 22, 2010 The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110 C for a period of 4 hours and cooled. aggregate impact value of the specimen. If the AIV is less than 10%, the aggregates are exceptionally strong, but if AIV is in range 10% until 30% the aggregates have good strength resistance. However, the aggregates impact value of the specimen for this laboratory experiment is 32.7%, 31.5%, 33.4% and 31.3%.

The L.A. Abrasion test uses larger dry samples and abrasive charges in a drum with a shelf. The shelf lifts and drops the sample and abrasive charge across the span of the drum, resulting in a very high impact on the aggregate particles. Loss from this test is a result of fracturing and dry grinding of the particles. The value of impact test changes to 23.33 to 35 for 10% to ... various test on fine aggregate, coarse aggregate, Marble ... of temperature and human errors.
