Toughness is the property of a material to resist impact.

. The aggregate impact value provides a relative measure of resistance to crushing under a gradually applied compressive load. The aggregate impact value gives a relation measure of the resistance of an aggregate to sudden shock or impact which in some aggregates differs from their resistance to a slowly applied compressive load. Sieves Seives required are 125 100 and 236 mm Fig.

No slots if it sieved on impact value pdf file or characteristics of lab report lawn sd learning from individual publication rate of. In this case. 20 Objectives To determine the aggregate impact value in the laboratory 30 Theory The property of a material to resist impact is known as.

The crushing value of aggregate W2W1 x 100. The crushing value of aggregates is measured in the ratio between the crushed aggregates obtained from the IS sieve 236mm and the weight of the dried aggregate sample. Weight of aggregates sieved by 236mm IS Sieve W2 3.

The aggregate samples of size 10mm to 125mm passing through 125mm sieve and retained on 10mm sieve are first taken and oven-dried at a temperature ranging from 100 degrees Celsius to 110 degrees Celsius for about four hours. Impact value of an aggregate is the percentage loss of weight particles passing 236mm sieve by the application of load by means of 15 blows of standard hammer and drop under specified test condition. The aggregate impact value is the ratio of the weight of the fraction passing through 236 mm weight W2 by the total weight of the sample weight W1 W2.

The impact value test has been conducted on aggregate to determine its bearing capacity against sudden impact. 1 civil engineering deparment dcc 3122 highway lab report title determination od aggregate impact value course session dcc 3122 geotechnic and highway laboratory prepare by group group a group members 1.

Test sieve and is retained on a 38 in BS. DCC3113 DETERMINATION OF AGGREGATE IMPACT VALUE. The aggregate intrinsic value is a saucepan of resistance to drive impact or agenda which.

Aggregate Impact Value W2 W1W2 100 80 gm 300 gm 2667 Impact Value Where W1 Weight of the fraction passing through a 236 mm IS sieve. Ainunyasmine binti haslan 03dka16f2023 2. Will impact value pdf lab report is reported.

The base of the machine should also have provisions for fixing its base. Crush samples having an impact value of 125 fall in the category of 10-20 therefore the aggregate test sample is classified as strong and can be seen in the table below. Total weight of dried aggregates W1 2.

Reduce the laboratory sample to produce a test portion of sufficient mass to produce three test specimen of 14 mm to 10 mm size fraction. To determine the aggregate impact value in the laboratory. Apparatus Required for Aggregate Impact Value Test-Impact testing machine.

Aggregate appropriate for cement wearing course should have maximum AIV of 30. The procedure of the impact value test includes the following series of steps. Level and plane concrete floor of minimum 45 cm thickness are used to support it.

Mohd iqbal naqiuddin bin zulkipli. 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. Thoroughly sieve the entire surface dry test portion on the 14.

The apparatus of the aggregate impact value test consists of. Aggregates may be dried by heating at 100-110 C for a period of 4 hours and cooled. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact which in some aggregates differs from its resistance to a slow compressive load.

The test sample shall consist of aggregates the whole of which passes through ½ in BS. The aggregate comprising the test sample shall be dried in an oven for a period of four hours at a temperature of 100-110 C and cooledThe measuring cup shall be filled about. Cut out how is aggregate test value test on labs can have tested material to use by another governmental authority reporting the course of.
