Feb 13, 2021 In this project, we have carried out certain tests like crushing test, impact test, abrasion test, stripping value test and test for specific gravity on conventional as well as plastic coated aggregates and the results are compared. The tests were performed on 0%, 5%, 5.5%, 6% and 8% of Mar 30, 2021 The ratio of aggregate which passes through the sieve to the total weight of sample in each test in terms of percentage is the impact value of aggregate. Now we compute the impact value using these two test using the formula below. Aggregate impact value W2/ W1 *100. where, W2 Weight of aggregate which passes through the IS sieve 2.36mm. W1 Weight of oven-dried aggregate. For good quality aggregate, the impact value

The flakiness index is found by expressing the weight of the flakey aggregate as a percentage of the aggregate tested. Test Method IS 2386 (P-1) 1963. Impact Value This test helps in determining the value which indicates the ability of an aggregate to resist crushing. Oct 03, 2019 Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load. Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height.

Dec 19, 2019 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%. further tests are carried out on other samples to get more accurate value. This can involve anything up to 100 test samples. Both the mass and the drop height can be varied. The impact energy is the kinetic energy of the mass at impact. The energy absorbed by the test specimen is the impact energy required to just fracture or break the specimen.

This test is not applicable to sizes smaller than 6.3mm. The Elongation index of an aggregate is the percentage by weight of particles whose greatest dimension (length) is greater than nine-fifths (1.8times) their mean dimension. This test is not applicable for sizes smaller than 6.3mm. Procedure of Shape Tests on Coarse Aggregates Aggregate Impact Value (AIV) Calculate the mean of the two results to the nearest whole number. Report the mean as the aggregate impact value, unless the individual results differ by more than 0.15 times the mean value. In this case repeat the test on two further specimens,

Jul 01, 2019 The apparatus of the aggregate impact value test consists of A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. Level and plane concrete floor of minimum 45 cm thickness are used to support it. The base of the machine should also have provisions for fixing its base. Mar 29, 2020 Flakiness index of aggregate test is conducted on coarse aggregates sample to estimate the shape of aggregates. For cement concrete types and base coarse and bituminous-construction, the presentence of flaky and elongated aggregate particles are considered undesirable as they may cause inherent weakness with possibility of breaking down under heavy loads.
